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. You will join a small, senior team with high ownership and direct product impact from day one.
About you
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
Benefits
- Work flexibly from Germany, UK, Italy, France, Ireland, Portugal, or Spain, with monthly Paris office visits (fully reimbursed)
- Regular team gatherings, including in‑person onboarding in Paris (1–2 weeks), yearly company offsite and team retreat, quarterly in‑person meetings, and social events
- 30 days annual leave plus local public holidays
- Competitive equity package with stock options/BSPCE, giving you ownership in our growing company
- €1,000 one‑time home office grant OR €400/month co‑working space stipend (remote outside Paris)
- €1,000 annual learning and development budget for training, courses, books, and skill development
- Private health insurance
- Relocation support (up to €10,000) for those choosing to move to France, including apartment finding and visa assistance
- Access to personalised mental health support, including 1:1 sessions with therapists or coaches, self‑care tools, and well‑being resources via MokaCare
- Sports and cultural activities reimbursement
Visa sponsorship and relocation support are only available for positions based in France. We cannot sponsor visas for remote positions outside of France.
