Senior Software Engineer

Senior Software Engineer – Industry Platform Team As a Senior Software Engineer on the Industry Platform team you will be responsible for architecting, implementing, and supporting integration solutions that connect internal and external applications. You’ll work closely with the rest of the team and others inside and outside the Technology department to deliver scalable APIs, services, and applications that enable seamless interoperability. A typical day would start with stand‑up, sprint planning, or retrospectives where you’ll collaborate with the team to align on priorities and unblock progress. From there, your time might be spent deep‑diving into code, debugging issues, refining future work, or reviewing the code of your colleagues. You’ll often work cross‑functionally, engaging with product owners, solutions architects, data engineering or stakeholders from other departments to clarify needs and ensure that what you’re building delivers real value. Some days are more collaborative, others are heads‑down and focused—whether you’re writing clean, scalable code, reviewing pull requests, or exploring ways to improve performance and reliability. We value autonomy, curiosity, and a pragmatic approach to problem‑solving. You’ll be trusted to own your work, contribute ideas, and help shape how we build software that helps us achieve our mission of a greener Britain.
