Job description: ## **About the Role** We’re hiring a Full Stack Engineer to build and scale end-to-end web applications across our platform. This role sits at the intersection of product, infrastructure, and applied AI, working closely with a small, fast-moving team to ship features that directly impact customers. You’ll own development across the stack: from frontend interfaces to backend APIs, data models, and external integrations. The environment is highly iterative, with a strong bias toward shipping, learning, and refining quickly. If you enjoy operating with autonomy, working on ambiguous problems, and building systems from first principles, this role is a strong fit. --- ## **What You’ll Do** * Build and maintain full-stack features across frontend (React) and backend (TypeScript APIs) * Design and implement scalable data models using NoSQL databases * Integrate third-party services (e.g., APIs, auth, payments, document systems) * Work with AI coding tools and agent-driven workflows to accelerate development * Own features end-to-end, from initial concept through deployment and iteration * Collaborate closely with product and design to translate requirements into shipped functionality * Improve system performance, reliability, and developer experience over time * Contribute to architectural decisions as the platform evolves --- ## **Qualifications** * 2–5 years of experience building production-grade web applications (excluding internships) * Strong proficiency in TypeScript and modern React frameworks * Experience designing and working with APIs and distributed systems * Familiarity with NoSQL databases and flexible data modeling patterns * Comfort using AI-assisted development tools (e.g., code generation, copilots, agents) * Experience in a startup or high-velocity environment preferred * Ability to operate independently and take ownership of ambiguous problems * Strong product intuition and focus on delivering user value
