As a Senior Python Engineer, you’ll be a foundational member of a small, elite engineering team (<10) shipping daily.
You will help drive the architectural maturity of our platform as we scale, ensuring our systems remain as elegant and durable as they are fast.
You’ll design and build scalable backend services using Python 3.12+, FastAPI, and gRPC on GCP.
You’ll develop complex payment flows via Stripe and handle sensitive PII with a HIPAA-aware posture.
You’ll provide high-leverage code reviews and help establish the standards that allow us to scale efficiently as our load increases.
You’ll use AI tools (Claude, Copilot) intelligently to accelerate development.

7+ years building backend systems in production with deep Python expertise.
Prior startup experience required — you know how to build in fast-moving environments and recognize when to favor "speed to market" vs. "architectural perfection."
Proven architectural judgment — you’ve handled APIs, distributed transactional systems, and cloud-native infrastructure (GCP preferred).
Security-minded — you have experience handling sensitive data (PII, payments, or healthcare-adjacent).
A builder's mindset — you write code that others can read six months later and you aren't afraid to refactor legacy paths into durable services.
High ownership, Team mentality — you understand what you ship, you value "strong opinions, loosely held," and you thrive in a collaborative team environment.

5X growth trajectory — your impact on our core systems will be visible and immediate.
Direct access to leadership — work in a flat organization where your technical insights drive product decisions.
Daily shipping velocity — a "test-heavy" culture and robust CI/CD (GitHub Actions/Cloud Deploy) means you see your work in production every day.
Mission that matters — more pets getting the preventive care they need because of the durable infrastructure you build.
Teammates who show up — kind, motivated, and genuinely collaborative
