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)
