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 Email is hidden with your working demos or GitHub profile. Show me what you've hacked on.

Railway | Infra eng - Storage, Infra (Platform) eng, Product Eng (full stack)| REMOTE (Worldwide) | https://jobs.ashbyhq.com/railway?utm_source=daymzwzj0p

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?

We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen

Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Three open roles (apply below!):

Third Iron | Senior Full-Stack Software Developer | REMOTE (US)

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. We sell our subscription-based services to libraries, and anyone affiliated with one of these libraries can use our software. We do not sell user data. 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.

If you’re interested in this fully remote position, we're interested to chat with you! Please email Email is hidden or apply at https://thirdiron.applytojob.com/apply/mck2vdxtux/senior-ful...
