Responsibilities
• Strengthen the frontend foundations every Mercury engineer builds on. Evolve our React, TypeScript, and Vite infrastructure to support teams in shipping ambitious product work with speed and confidence. • Help engineers move efficiently with automation. Use static analysis, local tools, and LLM coding tools to help engineers quickly resolve the schlep so they can focus on what matters. • Optimize our testing platform for fast feedback loops and high confidence. From unit tests to visual snapshots, you’ll provide the QA tools product teams need to move both quickly and safely. • Make our CI/CD pipelines stable, ergonomic, and fast. Mercury ships fast— dozens of deploys to prod per day, and hundreds more commits on PR branches. You’ll keep the pipeline humming so Mercury’s engineers stay in flow and customers see fixes faster. • Make our systems and organization observable. Drive decisions by unifying technical metrics from our tools with sentiment metrics from developer surveys. When that data doesn’t exist yet, you’ll build the observability that lets the team move with confidence. • Foster enthusiasm about frontend work at Mercury by making the good path the easy path, and by representing our work in larger venues.
