Job Description:

We are looking for a Senior Full Stack Engineer to join our PostgreSQL Developer Experience team. This team’s mission is bold and clear: Make building modern apps effortless, backed by the world’s most resilient Postgres database. As a full-stack engineering expert, you’ll transform complex PostgreSQL features into elegant, intuitive interfaces for developers. You’ll move with urgency and a bias for action, while exercising sound judgment to balance innovation, risk, and opportunity against release schedules and ambitious project scope. Our back-end systems are mostly implemented in Python, with bits of Go and C, while the front end is based on React and Typescript. In this role, you’re not just executing — you’re shaping the PostgreSQL experience for developers, making it delightful, discoverable, and effortless to adopt.

Job Responsibility:

Deliver E2E Developer Experience: Take ownership of the technical implementation across the full user journey — from onboarding and data migration to sustained usage, developer satisfaction, and growth opportunities
Build Intuitive Interfaces: Design and implement front-end applications, dashboards, and developer-facing tools that make PostgreSQL effortless to adopt and use
Obsess Over Usage Data: Instrument and monitor product usage to understand developer behavior, identify friction points, and drive data-informed improvements
Experiment & Iterate Quickly: Work in short cycles, shipping prototypes and features rapidly to test adoption and improve the experience
Work Across a Modern Codebase: Collaborate on a stack where back-end systems are primarily Python, with components in Go and C, while the front end is built on React and TypeScript, enabling you to contribute to a rich, full stack developer experience
Champion Quality at Speed: Deliver high-quality, maintainable code while embracing agility and rapid iteration, and actively participate in technical planning to guide architectural decisions and trade-offs
Collaborate Cross-functionally: Partner with back-end engineers, product managers, designers, and product advocates to ensure seamless, end-to-end developer workflows

Requirements:

Excellent development skills in Python, TypeScript, and React
Excellent understanding of SQL and databases, preferably PostgreSQL
Passion for developer experience and eagerness to make complex systems simple and enjoyable
Proactive, self-starter mentality and a can-do attitude
A track record of delivering developer-facing products or tools is a big plus

Nice to have:
