Senior Full Stack Engineer

At TRACT, we are building a more sustainable and resilient food and agriculture industry. Our mission? To remove the burden of data management and resolve the debate on methodology so companies can drive impact. With our SaaS platform, we empower organizations to focus their resources on making a real impact while driving positive change in the industry. About the Team We are a diverse and passionate team of about 40, committed to creating a sustainable impact and technological innovation. We believe in the power of collaboration and leverage our collective expertise to tackle complex challenges and drive meaningful change. Our cultural heartbeat & business decisions are shaped by our core values: ‘Accept the challenge,’ ‘Commit to learn,’ ‘Authentic & accountable,’ ‘Make momentum,’ & ‘Simplify & ship.’ These ensure that every team member can thrive and make a difference. About the Job As a Senior Full Stack Engineer at TRACT, you'll build our insights platform using spec-driven development. In practice that means the specification comes before the code: you write it, the team reviews it, and an agent implements against it. Your name is on both the spec and the commit. This changes where your time goes. Less of it on typing implementation, more on requirements, system design, acceptance criteria, and review. We don't ship code we don't understand. You'll work across the stack (Python, FastAPI, PostgreSQL, BigQuery, React with TypeScript) on trunk-based development behind feature flags. On significant initiatives you may step into the Lead Engineer role — shepherding an RFC or tech spec, aligning the team, acting as the point of contact for Product and Design.
