Senior Software Engineer – Customer Support

We’re looking for a Software Engineer to join our Level 3 Customer Support team, dedicated to UK government customers. This is a hands-on, hybrid role based in Central London (near Liverpool Street Station), with a minimum of two days per week in the office. Customer onsite visits are also required depending on the sensitivity of the customers and their project phase.

In this role you’ll be working on meaningful projects that directly support the public sector in the UK. You’ll have the autonomy to solve problems creatively, the opportunity to collaborate with different customers, and the satisfaction of seeing your work make a real impact.

You’ll be part of a small, focused team that works directly with the customers to ensure their systems run smoothly and efficiently. You’ll play a key role during go-live phases, supporting changes in workflows, writing reports, configuring integrations, and providing technical fixes.

Due to the nature of the work, SC clearance eligibility and a British passport are required, and participation in an on-call rotation is expected.
