The role

A senior developer is needed to provide technical leadership on the delivery of an AI-enabled tasking and workflow platform for a Defence programme. The application is moving out of Discovery into early Alpha, so you'll be shaping the build rather than maintaining someone else's.

You'll work in a mixed team of engineers from several suppliers, alongside a dedicated AI engineering capability. The platform combines Python/FastAPI services, React and TypeScript interfaces, Camunda workflow orchestration, modular services, data persistence, and integration with existing Defence tasking processes.

Despite the AI-enabled focus of the platform, this is primarily a software engineering role.

What you'll need

  • Significant experience delivering software in MOD, Defence Intelligence, National Security or comparable secure environments
  • Proven experience leading agile development teams
  • Strong engineering background across Python, FastAPI, REST APIs, React and TypeScript
  • Experience designing and delivering microservice architectures
