Job description

Job Description:

ROLE RESPONSIBILTILES

Key Responsibilities:

You’ll be at the heart of large-scale transformation, helping us reshape our technology stack and development culture. From test-driven development and CI/CD pipelines to lean, business-driven development and Kanban practices—you’ll help embed engineering excellence from the ground up.

Why This Role Stands Out:

Real Impact: Your code will directly shape the future of our business. You’ll see the results of your work fast.
Architectural Influence: Help guide key technical decisions as we refactor, rearchitect, and modernize using techniques like the strangler fig pattern.
Continuous Learning: We don’t just encourage learning — we require it. You’ll spend a minimum of 4 hours per week on deliberate technical growth.
Agile Culture: Join a team that's serious about lean thinking and Kanban, with leadership that walks the talk.
Exciting Roadmap: We're already 3 months into a multi-year plan involving CI/CD, automated unit and integration testing, and modern software delivery practices.

We know the environment isn’t perfect — yet. But we’re committed to doing things the right way, combining new feature delivery with technical debt reduction

Key Skills & Experience:

We’re looking for developers with experience in legacy system transformation and a passion for modern software practices. If you thrive in change, love writing clean, testable code, and want to help drive cultural and technical evolution — let’s talk.

Our current stack is MS SQL, Stored Procedures, SSRS, C#, Entity Framework, (MVC) Razor , Bootstrap and JQuery.

Salary will be commensurate with experience and job responsibilities. We offer excellent benefits. Only candidates who are eligible to live and work in the UK need apply.
