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)
