Senior Python Engineer (public API & Fastapi) - Remote Eligible

Senior Python Engineer – Public API

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

If you think you have what it takes but don't meet every single point above, please still apply. We'd love to chat and see if you could be a great fit.
