Senior FastAPI Engineer
Compensation: 100k to 110k* + Stock‑Options/BSPCE (Local currency)
Location: Remote with monthly Paris office visits (fully reimbursed). We can hire people already based in selected countries only: France, Germany, Ireland, Italy, Portugal, Spain, UK, Poland.
About the role
- You'll collaborate with the AI Tools squad to implement and improve AI features in the Photoroom app (Logo maker, AI Images, AI Videos, and other features available on the homepage of the app).
- You'll design and architect new features, chaining a mix of internal and external services to generate breathtaking images and videos for our users.
- You'll monitor and scale the growing load on the FastAPI service, leveraging Datadog to find optimisations and bottlenecks or implementing smart caching of pipeline steps.
About you
- You have experience designing and updating internal REST APIs operating at scale, collaborating with other teams to gather their requirements and monitoring and improving the performance of existing services, ideally with Datadog.
- You have a strong practical understanding of FastAPI or a similar async Python (has to be async).
- You know how to keep async actually async. You can identify blocking calls in async handlers, know when to offload CPU‑bound work to a thread, and treat protecting the event loop as table stakes.
- You have experience with integration testing in a large Python project and wiring multiple external services or APIs together reliably.
- You have worked in a fast‑paced startup in the past and thrive in high‑autonomy environments where you set your own direction and own outcomes end‑to‑end.
- Bonus: experience working with AI APIs in production.
