Requirements
- Strong experience building backend systems in Python, with a focus on APIs used by external consumers (not just internal services).
- Comfortable with FastAPI (or similar frameworks) and have worked with async patterns, concurrency, and production debugging.
- Owned or significantly contributed to the design of public-facing APIs — thinking about versioning, consistency, and long-term evolution.
- Care deeply about reliability, performance, and developer experience.
- Pragmatic and product-minded — prioritise impact and speed, and avoid over-engineering.
- Take ownership and are comfortable making decisions, while collaborating closely with cross-functional teams.
- Worked in high-performing teams, ideally in fast-paced or startup environments.
- Communicate clearly and can translate technical decisions into something others can understand.
- Experience with API deployment patterns (Docker, uvicorn/gunicorn, health checks, etc.)
- Worked with image processing libraries (Pillow, pyvips…)
- Integrated AI/image models behind APIs (latency, inference, abstraction)
- Experience with Node.js (current API is being migrated)
- Built integrations or developer-facing tooling
Responsibilities
- Design, build, and evolve our public API product, the core interface through which developers access Photoroom’s AI capabilities.
- Ship features used by both self-serve developers and large enterprise customers, ensuring the API remains reliable, scalable, and easy to integrate.
- Own the API surface end-to-end: from design decisions (naming, versioning, structure) to implementation, performance, and long-term maintainability.
- Iterate quickly based on real usage, we ship multiple times per week — using data and user feedback to prioritise what matters most.
- Work at the intersection of backend engineering and AI, abstracting complex image models into simple, elegant developer-facing interfaces.
- Collaborate closely with product, machine learning, backend, and sales teams to ensure the API delivers real value to users.
- Join a small, senior team with high ownership and direct product impact from day one.
