About the Role As a frontend-focused Senior Software Engineer you will own the design and delivery of the user-facing experiences at the heart of our AI products. You will build polished, performant, production-grade interfaces in React and TypeScript. You will also work in Go on backend services and APIs as needed. This is a high-autonomy, high-leadership role where you will develop new features at scale, set the standard for frontend, mentor engineers, and use AI-assisted tooling to ship faster than a traditional team.
Requirements 7+ years of proven experience as a software engineer with deep frontend specialization in React and TypeScript. Expert-level React and TypeScript, with a strong eye for UX, performance, and accessibility. Demonstrated fluency with AI and agentic coding tools (e.g., Claude), and a track record of using them to ship efficiently. Leadership experience: setting technical standards, mentoring engineers, and driving key technical decisions. A track record of shipping high-quality, production-grade frontend at scale. Working proficiency in Go (or the ability to become productive in it quickly) for backend services — secondary to frontend work.
Responsibilities Design, build, and own user-facing features in React and TypeScript — polished, accessible, performant, and production-ready. Set the technical direction and quality bar for the frontend and mentor engineers through code reviews. Use AI and agentic development tools such as Claude to move quickly and establish best practices. Dip into Go to build and extend the backend services and APIs behind your features. Collaborate with business stakeholders to architect and implement new experiences from inception to delivery. Contribute to product and technical roadmaps and to the broader direction of the engineering team. Craft and maintain user-facing technical documentation that drives understanding and adoption.
