ascertain - Senior/Staff Full-Stack Engineer — Brazil (Remote)
Requirements
• 7= years strong full-stack experience with Python (FastAPI or similar) and TypeScript with React. • Comfort designing schemas and writing non-trivial SQL against relational databases (we use PostgreSQL). • Working knowledge of containerization (Docker) and CI/CD pipelines. • Ability to communicate clearly in English, written and verbal — most async work happens in writing, and you'll regularly join meetings with U.S.-based teammates. • Meaningful overlap with U.S. Eastern business hours during the workday. • Experience in regulated environments (healthcare, fintech, etc.) and a security-minded approach to design. • Infrastructure-as-code experience (Terraform). • Familiarity with Redis, queueing systems, or other parts of a modern production stack. • Background in ambiguous, early-stage environments where you've had to take ownership without much scaffolding. • You're excited — not just willing — to learn new things, push past your comfort zone, and ship in a fast-moving environment. You communicate clearly, take ownership without being asked, and care about the people on the other end of your code.
Responsibilities
• Own product features end-to-end, from design through production. • Build user-facing experiences in React and TypeScript. • Design and ship backend services with Python and FastAPI. • Partner with product, design, and engineering peers to turn fuzzy problems into shipped software. • Raise the bar in code review and help shape our engineering practices. • Improve our development processes as we grow — testing, CI/CD, observability — the things that compound over time.
Benefits
• Meaningful equity and competitive cash compensation. • Fully remote within Brazil, with a flexible schedule. We trust people to manage their time and work like adults. • A small, mission-driven team with backgrounds across healthcare operations, product, and engineering. • Why Ascertain?
