Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Python Engineer (Public API & FastAPI) - **Company:** Photoroom - **Location:** Berlin, Germany (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** LTE (Telecommunication), Application Programming Interfaces (APIs), Artificial Intelligence, Software Debugging, Python (Programming Language), Machine Learning, Node.Js, Systems Integration, Management of Software Versions, Backend, Fastapi, Low Latency, Text Summarization, Api Design, Docker - **Published:** May 22, 2026 - **Apply:** https://de.indeed.com/viewjob?jk=cde1a72be4f5c4b5 ## About the Role Do you have experience in Python?, * You have strong experience building backend systems in Python, with a focus on APIs used by external consumers (not just internal services). * You are comfortable with FastAPI (or similar frameworks) and have worked with async patterns, concurrency, and production debugging. * You have owned or significantly contributed to the design of public-facing APIs - thinking about versioning, consistency, and long-term evolution. * You care deeply about reliability, performance, and developer experience. * You are pragmatic and product-minded - you prioritise impact and speed, and avoid over-engineering. * You take ownership and are comfortable making decisions, while collaborating closely with cross-functional teams. * You have worked in high-performing teams, ideally in fast-paced or start-up environments. * You communicate clearly and can translate technical decisions into something others can understand. Bonus Points * Experience with API deployment patterns (Docker, uvicorn/gunicorn, health checks, etc.) * Experience with image processing libraries (Pillow, pyvips…) * Experience integrating AI/image models behind APIs (latency, inference, abstraction) * Experience with Node.js (current API is being migrated) * Experience building integrations or developer-facing tooling ## Description 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 * We can go higher for outstanding profiles and adjust for the cost of living where needed. About the Role * You will design, build, and evolve our public API product - the core interface through which developers access Photoroom's AI capabilities. * Public API experience is a must-have. * You will ship features used by both self-serve developers and large enterprise customers, ensuring the API remains reliable, scalable, and easy to integrate. * You will own the API surface end-to-end: from design decisions (naming, versioning, structure) to implementation, performance, and long-term maintainability. * You will iterate quickly based on real usage - we ship multiple times per week - using data and user feedback to prioritise what matters most. * You will work at the intersection of backend engineering and AI, abstracting complex image models into simple, elegant developer-facing interfaces. * You will collaborate closely with product, machine learning, backend, and sales teams to ensure the API delivers real value to users. ## Related Videos - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Stop using Node.js like in 2020!
