Senior Backend Engineer

About the Role

We're hiring Senior Backend Engineers to own backend product development end-to-end from APIs and data models to the systems that orchestrate AI agents, run asynchronous workloads, and power knowledge retrieval.

Our backend is built with TypeScript/NestJS and Python, running on PostgreSQL and AWS. You'll work across both.

Experience: 8–10 years building production-grade backend systems.

What You'll Do
Shape ambiguous product problems into technical designs. Work directly with product and design to pressure-test requirements, propose alternatives, and choose the simplest solution that actually solves the user's problem.
Own backend features end-to-end — including API design, data modelling, implementation, rollout, and production operations. You ship it and you run it.
Work across our AI and agent systems, including prompt and context design, tool execution, multi-provider LLM integrations, and streaming responses.
Design and operate resilient asynchronous systems, including queues, retries, idempotency, cancellation,



observability, and fault tolerance. Our workloads are long-running and failure-prone by nature; correctness under partial failure is the job.
Build ingestion pipelines that turn diverse content into structured, searchable, and retrievable knowledge.
Build integration layers against third-party platforms, normalising inconsistent APIs, authentication models, and content formats behind reliable internal contracts.
Design schemas and run live migrations against production data without downtime.
Improve reliability, performance, and observability across production systems.

Must Have
Solid production experience with Node.js and TypeScript, ideally with NestJS. Experience with Express or Fastify is also relevant.
Robust production experience with Python, including asynchronous programming. Experience with FastAPI, Django, Flask, asyncio, Celery, or equivalent technologies.
