Zoca | AI Engineer | Full-time | Bangalore (In-office)
I'm Shambhav, CTO & co-founder at Zoca. I'm building a team to push the boundaries of what's possible with AI.
So far, we've built a platform from Bangalore that has outperformed every competitor in our space — small businesses happily pay us 10x our competitors' price because our agents actually work. These agents work like real business partners, generate leads, do followups, book appointments, manage reviews and more. We're already powering growth for over a thousand businesses.
In the next 12 months, we're going to scale this to tens of thousands, while making the agents smarter, more reliable, and capable of things people think aren't possible today. We'll be working on technical challenges like multi-channel conversations, browser automation at scale, retrieval pipelines, and real-time monitoring/eval loops.
I need AI Engineers who want to build like founders — not paper over things in a research repo, but ship production systems that touch real users. Strong TS/Python skills, a builder's mindset, and a track record of actually building (agents, GSoC projects, or similar) is what I'm looking for.
If this excites you, send me an email at shambhav@zoca.com with your working demos or GitHub profile. Show me what you've hacked on.

Our company has been remote-first since we began in 2011. You’ll join a team with plenty of experience putting into practice what works well remotely, and avoiding what doesn’t.

Our focus is on building the best software to enable research that changes the world.
We’re looking for a developer interested in full-stack work, since we have a variety of upcoming initiatives, some being mostly front-end, some being mostly back-end, and some a balance of the two.
The front-end of our stack primarily consists of JavaScript, using EmberJS for two major projects, and React for two others. Our backend is written in NodeJS, and features data storage using PostgreSQL, Elasticsearch, and CouchDB, and hosting primarily on AWS and HEroku.

What Stripe did for payments, Pylon is doing for the mortgage industry: We're taking a sleepy industry with backward technology and re-building the stack from the ground up. We're first-principles thinkers, and our team is small, talented and ambitious.
I'm hiring generalists who love coding and want to build something beautiful in an industry where technology written in the 90s is the norm. We're Series A, well funded, and we have traction with customers. Come to Menlo Park and help us turn the $13 trillion US mortgage industry into a set of APIs.
Devyce (YC S22) | UK (remote/onsite/hybrid) | Senior Frontend/Fullstack/Backend Developers | Full Time
We're redesigning the business phone network from the ground up. Starting with mobile apps and a softphone, we're losing the jargon (who cares what an IVR is?) and building features customers actually want. We're getting big enough to start splitting into more focused teams and there's a few different areas that we need; our infra needs a lot of work, we have big dreams for some cool AI agent/pipeline work and there's still a lot of more fundamental phone system specific problems we need to solve.
We try to be flexible around work and don't believe in regular 60-hour weeks. One key aim of our product is to help employees maintain a healthy work/life balance (who wants to be disturbed by business calls on the weekends?) in an age of remote and hybrid work. The founders lead by example, with all of us having worked 4-4.5 day weeks at times in order to spend time with our children.
We're looking for full stack software engineers - doesn't matter if you're much stronger in either the front or back end, but you do need to be able to build all the parts of a feature - there's no "front end team" once the backend is done. There is naturally work that's much more one sided, so you won't be stuck for months on the front end if you prefer the backend, but we're still a small startup so we expect you to get stuck in and help out where you can!
You'll need to visit our London office roughly once a month.

Actively AI| Multiple Roles | In office in NYC | Salary + Equity
What Cursor has done to revolutionize coding, we are looking to do for revenue. Every large company spends 40-50 cents of every dollar they earn on sales & marketing, and it’s very inefficient because data lives in so many different systems, sales reps are stretched thin doing manual work, and products are rapidly evolving.
It’s why we are building the agent and intelligence framework for enterprise scale GTM that guides every sales motion across the funnel — from SDR outreach to AE deal strategy to cross-sell and expansion. It’s an intelligence layer that sits on top of every sales tool and with external browsing that is then customized to your specific products & GTM motions.
It’s a massive technical challenge:
- Intelligence at scale: modeling millions of accounts, real-time signals, and contextual history into per-account reasoning agents.
- AI Agents & Chat: designing systems across “push” (recommendations) and “pull” (interactive assistants), with extensible skills customers can train themselves.
- Data & Infrastructure: creating a new framework for real-time, per-customer agents that simplifies pipelines, scales efficiently, and cuts costs (we’ve already cut cost per account by 50% through smarter eval-driven approaches).
- Wall-to-wall product: from self-serve UI to Slack integrations, from predictive models to generative copilots — we’re building an AI operating layer for GTM.
Why Join Engineering at Actively:
- Customer-driven impact: engineers directly go onsite and spend time with customers, deploying agents that reshape workflows at companies like Samsara and Justworks.
- Category creation: there’s a huge opportunity to build the pre-dominant AI company for GTM with a massive TAM
- Cutting-edge AI: opportunity to push the frontier of reasoning agents, eval-driven development, and scalable intelligence.
- High-caliber peers: we’re ex-Instacart, Scale AI, Stanford AI researchers, and operators who’ve built at scale before.

Our product is built around a power object model which combines document editors with and proprietary programming languages for financial modeling, computable contracts, etc, in order to build one of the more unique RLHF feedback loops that we've seen to date.
A primary technical bet is that if we can productize version control properly, we can capture annotated "diffs" of user information with user-validated annotations. By doing so, we create path-dependence, which enables us to specify system-level goals for agents to solve for.
Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.
We're venture-backed by one of the best deeptech funds in the market and are hiring for roles spanning product engineers, CRDT wizards, and compiler/calculation engine leads.

So reach out if you think you're a good fit.

You'd be working directly with me, solo founder, our senior engineers, and marketing and support colleagues, and hopefully take on a growing role over time to treat the business like your own. It's a very low key work environment, but independent and plenty of responsibility and ownership for the right person.

Testimonial from a team member: “Long story, but I worked there for maybe 6ish months part time a while back. They offered me full time, but I ended up going to a startup because I wanted to learn some specific technologies + up my skills in Data Science. That job was definitely good for some people, but it wasn’t as remote as they advertised it (had me fly in a lot), and the team was somewhat difficult to work with ;) I ended up starting my own consulting and at the same time CourtDrive reached back out to me (perfect timing). Point I was trying to make was that I went back to work with them because they were so nice to work with. Not super demanding and very open to listening to ideas/suggestions - just a pleasant environment.”

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re hiring on the backend to help solve one of the hardest problems in data engineering: building a production knowledge graph from millions of fragmented, inconsistent Chinese corporate records where traditional approaches break down. Our PySpark/EMR/Airflow pipeline is just the foundation. The real challenges are in entity resolution across transliterated names and obfuscated ownership structures, bipartite matching algorithms and inferring relationships. We build our product on top of that with a Django/FastAPI/React stack to help our users access that knowledge graph to analyze and investigate any risks they should be aware of.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
Happy to answer any questions - you can reach out to me here or at leo.green@wirescreen.ai - I'm a recruiter with WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.

We've been improving our hiring process over time, and we know some good candidates may have fallen through the cracks. Some people who tried in the past have had success going through it again, and we still pay for hiring projects.

Zoca | AI Engineer | Full-time | Bangalore (In-office)
I'm Shambhav, CTO & co-founder at Zoca. I'm building a team to push the boundaries of what's possible with AI.
So far, we've built a platform from Bangalore that has outperformed every competitor in our space — small businesses happily pay us 10x our competitors' price because our agents actually work. These agents work like real business partners, generate leads, do followups, book appointments, manage reviews and more. We're already powering growth for over a thousand businesses.
In the next 12 months, we're going to scale this to tens of thousands, while making the agents smarter, more reliable, and capable of things people think aren't possible today. We'll be working on technical challenges like multi-channel conversations, browser automation at scale, retrieval pipelines, and real-time monitoring/eval loops.
I need AI Engineers who want to build like founders — not paper over things in a research repo, but ship production systems that touch real users. Strong TS/Python skills, a builder's mindset, and a track record of actually building (agents, GSoC projects, or similar) is what I'm looking for.
If this excites you, send me an email at shambhav@zoca.com with your working demos or GitHub profile. Show me what you've hacked on.

Do you want to develop software that helps scientists, doctors, and historians discover breakthroughs? Join our small, fully-distributed software development team to help connect scholars of all disciplines with peer-reviewed journal articles.
Our company has been remote-first since we began in 2011. You’ll join a team with plenty of experience putting into practice what works well remotely, and avoiding what doesn’t. Third Iron has never taken VC money, and we’ve never had layoffs. Our approach to hiring and selling our products helps us feel confident that this pattern will continue far into the future.
Third Iron software is used by researchers at over 1,500 libraries, including universities, hospitals, corporations, and government agencies located in over 35 countries.
In a refreshing change from advertising-dependent tech companies and those who sell user data, we instead have a business-to-business model.

Our focus is on building the best software to enable research that changes the world.
We’re looking for a developer interested in full-stack work, since we have a variety of upcoming initiatives, some being mostly front-end, some being mostly back-end, and some a balance of the two.
The front-end of our stack primarily consists of JavaScript, using EmberJS for two major projects, and React for two others. Our backend is written in NodeJS, and features data storage using PostgreSQL, Elasticsearch, and CouchDB, and hosting primarily on AWS and HEroku.

Devyce (YC S22) | UK (remote/onsite/hybrid) | Senior Frontend/Fullstack/Backend Developers | Full Time We're redesigning the business phone network from the ground up. Starting with mobile apps and a softphone, we're losing the jargon (who cares what an IVR is?) and building features customers actually want. We're getting big enough to start splitting into more focused teams and there's a few different areas that we need; our infra needs a lot of work, we have big dreams for some cool AI agent/pipeline work and there's still a lot of more fundamental phone system specific problems we need to solve.
We try to be flexible around work and don't believe in regular 60-hour weeks. One key aim of our product is to help employees maintain a healthy work/life balance (who wants to be disturbed by business calls on the weekends?) in an age of remote and hybrid work. The founders lead by example, with all of us having worked 4-4.5 day weeks at times in order to spend time with our children.
We're looking for full stack software engineers - doesn't matter if you're much stronger in either the front or back end, but you do need to be able to build all the parts of a feature - there's no "front end team" once the backend is done. There is naturally work that's much more one sided, so you won't be stuck for months on the front end if you prefer the backend, but we're still a small startup so we expect you to get stuck in and help out where you can!
You'll need to visit our London office roughly once a month.

Actively AI| Multiple Roles | In office in NYC | Salary + Equity
What Cursor has done to revolutionize coding, we are looking to do for revenue. Every large company spends 40-50 cents of every dollar they earn on sales & marketing, and it’s very inefficient because data lives in so many different systems, sales reps are stretched thin doing manual work, and products are rapidly evolving.
It’s why we are building the agent and intelligence framework for enterprise scale GTM that guides every sales motion across the funnel — from SDR outreach to AE deal strategy to cross-sell and expansion. It’s an intelligence layer that sits on top of every sales tool and with external browsing that is then customized to your specific products & GTM motions.
It’s a massive technical challenge: - Intelligence at scale: modeling millions of accounts, real-time signals, and contextual history into per-account reasoning agents. - AI Agents & Chat: designing systems across “push” (recommendations) and “pull” (interactive assistants), with extensible skills customers can train themselves. - Data & Infrastructure: creating a new framework for real-time, per-customer agents that simplifies pipelines, scales efficiently, and cuts costs (we’ve already cut cost per account by 50% through smarter eval-driven approaches). - Wall-to-wall product: from self-serve UI to Slack integrations, from predictive models to generative copilots — we’re building an AI operating layer for GTM.
Why Join Engineering at Actively: - Customer-driven impact: engineers directly go onsite and spend time with customers, deploying agents that reshape workflows at companies like Samsara and Justworks. - Category creation: there’s a huge opportunity to build the pre-dominant AI company for GTM with a massive TAM - Cutting-edge AI: opportunity to push the frontier of reasoning agents, eval-driven development, and scalable intelligence. - High-caliber peers: we’re ex-Instacart, Scale AI, Stanford AI researchers, and operators who’ve built at scale before.

Testimonial from a team member: “Long story, but I worked there for maybe 6ish months part time a while back. They offered me full time, but I ended up going to a startup because I wanted to learn some specific technologies + up my skills in Data Science. That job was definitely good for some people, but it wasn’t as remote as they advertised it (had me fly in a lot), and the team was somewhat difficult to work with ;) I ended up starting my own consulting and at the same time CourtDrive reached back out to me (perfect timing). Point I was trying to make was that I went back to work with them because they were so nice to work with. Not super demanding and very open to listening to ideas/suggestions - just a pleasant environment.”

WireScreen (Series A) | Senior Software Engineer | NYC - hybrid | Full-time | $165k-$200k base + equity | https://jobs.ashbyhq.com/wirescreen/158fd72f-fc2f-47a3-bdb5-...
WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.
We’re hiring on the backend to help solve one of the hardest problems in data engineering: building a production knowledge graph from millions of fragmented, inconsistent Chinese corporate records where traditional approaches break down. Our PySpark/EMR/Airflow pipeline is just the foundation. The real challenges are in entity resolution across transliterated names and obfuscated ownership structures, bipartite matching algorithms and inferring relationships. We build our product on top of that with a Django/FastAPI/React stack to help our users access that knowledge graph to analyze and investigate any risks they should be aware of.
If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.
Apply here: https://jobs.ashbyhq.com/wirescreen/158fd72f-fc2f-47a3-bdb5-...
Happy to answer any questions - you can reach out to me here or at leo.green@wirescreen.ai - I'm a recruiter with WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.
