Desired Skills (Good if you have): Cloud Platforms (AWS), System Design, Application Security
What is the role all about?
We're hiring full-stack engineers who build with AI, not the traditional way. You should be fluent in modern web engineering, primarily Node.js, and just as fluent in using LLMs and AI tools (Cursor, Claude Code, and similar) to ship fast. Work that once took a month should take a week; what took a week should take a day.
The role spans a range, from architecting backends for non-trivial products like assistants and agents, to rapidly turning a requirement into a clean, customer-facing app or MVP. Be strong in at least one area, be comfortable across the system as a whole, and tell us where you're strongest so we can place you accordingly.
What will you do?
- Plan, build, and ship product features end-to-end, with AI embedded where it has the most impact.
- Integrate LLMs and AI APIs into production-grade applications.
- Use AI tools to prototype, build, and deliver at high speed without sacrificing quality.
- Design scalable APIs and data models with Node.js, Express.js, and MongoDB.
- Build responsive, performant, customer-facing interfaces with React/Next.js.
- Contribute to design discussions, code reviews, and architectural decisions.
What are we looking for?
AI leverage:
- You've shipped real things using LLMs or AI APIs and instinctively reach for AI to move faster.
- Comfortable with prompt engineering and judging AI output for production-readiness.
Engineering depth and delivery:
- Solid fundamentals: problem-solving, data structures, and how systems fit together.
- At least 2+ years across frontend (React/Next.js), APIs (Node.js/Express.js), and databases (MongoDB).
- You write clean, production-grade code and you ship.
- Knowledge of application security or ethical hacking is an advantage.
Culture
- Work with performance-oriented teams driven by ownership and passion.
- Learn to design systems for high accuracy, efficiency, and scalability.
- No strict deadlines, focus on delivering quality work.
- Meritocracy-driven, candid culture. No politics.
- Very high visibility regarding which startups and markets are exciting globally.
