The financial industry is growing at a record pace, but our data providers are still stuck in the past — with cumbersome onboarding processes, complicated APIs, slow infrastructure, and expensive licensing costs. Databento is the market data platform for modern finance. The company provides real-time and historical data across futures, options, and equities through a unified API. By owning the entire market data stack end-to-end, Databento is the first platform of its kind to combine the performance and reliability demanded by the world's leading trading firms with a dramatically simpler developer experience. Our team includes alumni of Two Sigma, Citadel Securities, Flow Traders, Tower Research, PDT Partners, SIG, and other top quantitative firms. We're looking for a midlevel or senior IC to join our Platform/API engineering team. You'll be responsible for building, maintaining, and promoting our JavaScript client library, working closely with our design team to bring production-ready interfaces to life. This role is primarily focused on TypeScript/JavaScript, with some full-stack/Python work as well. Responsibilities - Own, build, and maintain our JavaScript client library, ensuring it is robust, well-tested, and easy for external users to integrate with. - Integrate native libraries into JavaScript/TypeScript code using tools like N-API, node-addon-api, or Wasm. - Build responsive, performant front-end applications using React, Redux, Vite, Web Workers, and WebSockets. - Contribute to full-stack projects, including backend work in Python (or Rust), REST API design, and database/migration work. - Work between design and engineering teams to translate designs (e.g. Figma handoffs) into production-ready components and design systems. - Set up and maintain CI/CD pipelines, including publishing to npm. - Document components using Storybook or similar tooling. - Collaborate cross-functionally to ensure smooth feature rollouts and updates. Preferred background - Experience working between high-performing design and engineering teams, including production-ready design systems and tools (e.g. Figma handoffs). - Proficiency with React, Redux, Vite, Web Workers, and WebSockets. - Background in trading, market data, or quantitative finance. - Hands-on backend experience building APIs, working with databases, and migrations. - Full-stack experience with backends in Python or Rust, including REST API design. - Familiarity with Storybook or similar component documentation tooling. - Good communication skills and work ethic for a remote workplace.
