Senior Software Engineer

Are you an experienced Software Engineer looking for your next challenge in a fast-paced, cloud-first, product-driven engineering environment? Do you enjoy building high-quality software, solving complex technical problems, and helping other engineers around you grow?

As a Senior Software Engineer, you will be hands‑on within a cross-functional Agile/Dev Ops team, designing, building, and supporting scalable customer and business-facing systems. You will play a key role in delivering secure, reliable, and maintainable solutions, while contributing to technical direction, engineering best practice, and continuous improvement across the team.

You will work closely with fellow engineers, Product Owners, Delivery Managers, and Architecture teams to help translate business and architectural requirements into well-engineered technical solutions. You will also be part of a wider engineering community, contributing to shared standards, modern ways of working, and the adoption of new technologies including AI-assisted software development.

This position will be based working remotely with the occasional visit fortnightly/monthly to our bright and modern offices in Welwyn Garden City.

• Hands-On Engineering: Design, build, test, deploy, and support high-quality software solutions in a fast-paced product engineering team.
