Fullstack Developer (Go / Python) — AI Infrastructure

About the role

We build and run the infrastructure behind a high-throughput AI platform — prompt routing, caching layers, and the data pipelines that keep millions of tokens moving with minimal latency. This is a fullstack role weighted toward the backend. You'll spend most of your time on services, APIs and data stores, and the rest on the developer dashboards that sit on top of them.

Key responsibilities

• Build and maintain the backend services behind our prompt routing engine.
• Hunt down latency. Profile, measure, and cut overhead out of the hot path.
• Design schemas and optimise queries across relational and non-relational stores.
• Ship the API surface (REST and gRPC) that our dashboards and SDKs consume.
• Deploy and monitor cloud resources, and keep availability high.
• Write the unit, integration and end-to-end tests that let us ship without fear.

About you

• 2+ years of professional software engineering experience in production.
• Strong Go or Python. One of the two is non-negotiable for this role.
• Solid grasp of concurrency, async patterns, and building RESTful or gRPC APIs.
• Working TypeScript and Node.js, plus enough React / Next.js / Vue to build and maintain internal dashboards.
• Production experience with SQL (PostgreSQL, MySQL) and/or Redis, MongoDB or ClickHouse.
• Hands-on AWS or GCP, Docker, and modern CI/CD.
• A real testing habit — go test, pytest, Jest, whatever your stack. You write testable code by default.
• Instinct for time and space complexity, memory behaviour, and where the bottleneck actually is.
