About the Role

Senior Full-Stack Software Engineer

London (Victoria) - 3 days in office - £100,000 - £120,000 - Permanent

The opportunity

This is a rare greenfield engineering role at a genuinely early-stage business. The successful candidate will join a small, senior founding team and take real ownership of the technical foundation from day one - building the stack, setting the architecture, and establishing the patterns that everything else will be built upon. The role spans customer-facing product, backend automation, AI agent orchestration and internal tooling - with significant scope to grow as the business scales.

What you'll be doing

  • Building the customer-facing platform from the ground up - timelines, task-based views and embedded AI assistance
  • Owning backend automation workflows, AI agent orchestration and data pipelines
  • Building internal tooling to support the team in reviewing and approving AI-generated work
