• Automation – Python and Bash

• Experience delivering within the UK Government Digital Service (GDS) lifecycle on a public sector engagement

Why join?

You’ll work on complex, high-impact transformation programmes where engineering, security and technology come together.

You’ll have access to extensive learning and development opportunities, professional certifications and flexible hybrid working — with the opportunity to shape DevSecOps practices across a growing technology environment.
