About

About the Company
An established travel-tech business with over a decade in the market. Their B2B platform helps travel agents manage bookings, payments and customer interactions, and is trusted by thousands of daily users.

The engineering team is small, close-knit and works directly with the founders. New projects have just been approved, and the focus now is modernising the platform and architecture for the next stage of growth.

Engineers here get real ownership, your input shapes technical decisions, not just your delivery.

About the Role
You'll help modernise a large legacy platform built on .NET Framework, migrating it to a modern .NET architecture. This means moving from a monolith to scalable services connected through modern Web APIs.

You'll work closely with senior engineers and the founders on code quality, architecture and performance, plus deliver major feature migrations into the new platform.

The team also uses AI tools like Copilot, Claude Code and Codex. Part of your role is reviewing AI-generated code to make sure it's production ready. The platform runs on Azure, and you'll contribute to API design, authentication and deployment practices.

What You'll Bring
  • Strong C# and modern .NET experience
  • Experience designing scalable APIs
  • Solid backend architecture and system design skills
  • Experience refactoring or modernising legacy systems
  • Experience building integrations
  • Azure and cloud experience
  • CI/CD and modern deployment practices
  • Familiarity with AI dev tools (Copilot, Claude Code, Codex)
  • Strong problem-solving and the confidence to propose solutions
Why Apply?
Real impact, real ownership, and the chance to modernise a platform that matters, within a small team that moves fast and works closely together.
