The Role

We’re looking for a versatile Backend Engineer who’s strong in PHP/Python and excited to build the technical foundations for AI-powered features.

You’ll collaborate across an international engineering team, mentor other engineers, and help set high standards for quality, reliability, and developer experience.

Responsibilities

Own & evolve our backend: Improve performance, reliability, and maintainability of existing PHP and Python services (e.g. refactors, migrations, test coverage, resilience, cost/perf tuning).

Build new services & APIs: Design, implement, and operate secure, well-documented REST endpoints and event-driven systems that our mobile and web apps love.
Lay the AI foundations:

1) Stand up data pipelines and storage for embeddings & retrieval (e.g. vector indices, feature stores).

3) Integrate hosted LLMs and/or self-hosted inference as appropriate, with observability and cost controls.
