Website: Requirements Minimum 8 years of backend engineering experience at product-based organisations, including real startup experience.

Responsibilities Build and improve customer-facing features in a multi-tenant Go and PostgreSQL backend.

Make workflows safe to rerun and detect drops in output quality. Keep features reliable and responsive across workspaces with 100 to 100,000 accounts. Support production operations across AWS, Docker, enterprise, and on-premise deployments.
