Role Overview:
We're looking for a Senior Full-Stack Developer who doesn’t just write code—but builds systems, owns features end-to-end, and leverages AI tools to move fast and build smart. This isn’t a ticket-taking role. This is for builders who can architect, develop, and ship independently, with a bias toward action and clarity.
If you live inside your terminal, talk to Co-pilots like your pair programmer, and obsess over clean APIs and smooth user flows—let’s talk.
What you’ll do
- Take full ownership of features from problem → design → code → deploy → iterate
- Build modular, scalable APIs and frontend components using the MERN stack
- Use AI tools to write, debug, optimize code, and unblock yourself fast
- Integrate 3rd-party APIs, services, and AI capabilities where relevant
- Collaborate async with product, design, and other engineers
- Optimize performance, scalability, and dev workflows
- Own dev hygiene—documentation, tests, Git practices, CI/CD pipelines
Must-Haves:
- Bachelor’s degree in Computer Science, Engineering, or a related technical field
- 4–5 years of full-stack experience in production-grade MERN apps
- You’ve shipped products end-to-end, not just maintained features
- Strong in JavaScript/TypeScript, both on frontend and backend
- Solid foundation in system design, API design, and debugging
- Comfortable using AI-native tools to code faster and better
- GitHub is your second home. You write clean commits and structured PRs
- Cloud/infra experience (Vercel, AWS, Docker/Kubernetes)

About Us
Bimaplan is an affordable insurance platform for the next billion Indians. Our vision is to provide financial security to 150 million underserved Indian households through affordable life and health insurance. Increasing mobile penetration and evolution of digital infrastructure in India has now made it possible to reach this vulnerable population. We work with insurers to co- create affordable insurance plans and distribute through a vernacular app and a flexible referral network.
Bimaplan is founded by Vikul Goyal, and backed by Y Combinator. Vikul has extensive experience as a start-up founder and early stage investor in India. His previous start-up, Carcrew, was recently acquired by TVS. Vikul has an MBA from Harvard Business School, and a B.Tech. in Mechanical Engineering from IIT Guwahati. Our CTO, Chandan Mittal, is a Computer Science graduate from IIIT, and comes with five years of experience building scalable products at Amazon, Sharechat, and Udaan.
We are backed by some of the best global early-stage technology investors, prolific fintech founders, and experienced insurance industry veterans.

- have good communication skills. We don't need the best. As long as you can recite 'ba-ba black sheep' without a pause or two, it should do!
