[Hiring] Senior Fullstack Engineer @Monks

Role Description

Build across the stack and ship features that hold up. As a Senior Fullstack Engineer, you work across React / Next.js and Node / TypeScript to design, build, and ship features that stay reliable in production.

• Design, build, and maintain features across the frontend (React / Next.js) and backend (Node / TypeScript).
• Build and consume APIs, and model the data behind them.
• Review code, including AI-generated code, for quality and consistency.
• Collaborate with product, design, and other engineers to ship end to end.
• Troubleshoot and resolve production issues.
• Contribute to the team's standards, tooling, and practices.

Qualifications

• 5+ years building and shipping full-stack web applications.
• Strong TypeScript: React and Next.js on the front end, Node on the back end.
• Solid API design and data modeling.
• Experience building on AWS.
• Good testing habits and an eye for maintainable code.
• Strong English communication skills.
• Comfortable in a fast-paced, agile consulting environment.

Requirements

• Comfortable across the whole stack: you move between frontend and backend without friction.
• Ownership-minded: you take a feature from idea to shipped, and you sweat the details.
• A pragmatic problem-solver: you pick the simplest thing that works and holds up.
• A clear communicator: you keep clients and teammates in the loop without noise.

Extra Credit

• You've worked on AI-heavy products or integrated LLMs.
• Deep PostgreSQL experience.
• You've built or maintained a design system.
• Familiarity with CI/CD and DevOps practices.
• Open-source work you're proud to link.
