About the roleWe're scaling the infrastructure and the products behind a fast-growing AI platform. This role sits right in the middle of it: high-throughput routing engines on one side, developer-facing dashboards on the other, and you moving freely between the two.If you're the kind of engineer who gets bored being fenced into one layer, this is the one.What you'll do- Own features end to end. Design, build and maintain them across backend services and frontend applications.- Optimise for speed. Cut latency overhead out of our prompt routing pipeline.- Manage the data layer. Schema design, query optimisation and data modelling across relational and non-relational stores.- Support the infrastructure. Deploy, monitor and manage cloud resources so our services stay available.- Hold the quality bar. Comprehensive unit, integration and end-to-end tests are part of shipping, not a follow-up ticket.
