Job description

We're seeking a Lead Full Stack JavaScript Engineer to deliver production-ready features across the entire stack — spanning database, API, and UI layers — and to integrate AI-assisted development as a core part of daily work rather than a peripheral skill. You'll take ownership of feature development on our technology stack (Node.js, React, PostgreSQL/Redis, AWS or other cloud), leveraging tools such as GitHub Copilot, Cursor, or Claude Code as everyday production tools.

• Design, build, and ship full stack features across the JavaScript/TypeScript stack — frontend (React, Next.js), backend (Node.js), and the database layer
• Take full ownership of tasks from implementation through testing, code review, and documentation
• Leverage AI coding assistants (GitHub Copilot, Cursor, Claude Code, or similar) on a daily basis to implement tasks, generate tests, debug, and explore the codebase
• Utilize prompt engineering and context management techniques to achieve reliable, targeted output from AI tools
• Critically evaluate AI-generated code prior to merging — confirm correctness, identify hallucinated logic, and fully understand every shipped change
• Connect with cloud infrastructure (AWS/Azure/GCP) and third-party services as required
• Engage in code reviews, architecture discussions, and sprint planning sessions
