Senior Python Engineer (FastAPI / Python) @ Photoroom

About Us

Photoroom launched in 2020 after being accepted into Y Combinator and has become the world's most popular AI photo editor over the past four years. Our goal is to create the technology allowing anyone create studio-level product images in minutes.

With over 300 million downloads and processing 5+ billion images annually, we serve both individual creators and major enterprises like Amazon, DoorDash, and Decathlon through our B2C app and B2B API solutions.

We're a profitable, remote-friendly company that has raised Series B funding and aims for 40% year-over-year growth. Our team of 100+ passionate builders focuses on craft, innovation, and collaboration, creating exceptional impact for entrepreneurs and businesses worldwide.

About the Role

You will design, build, and evolve our public API product — the core interface through which developers access Photoroom’s AI capabilities.

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 startup environments.

You communicate clearly and can translate technical decisions into something others can understand.
