Full Stack Software Engineer

Ref: ZR_9562_JOB  ·  Posted on 26 August 2026

Introduction

Our client is an established, highly respected technology and engineering firm working at the cutting edge of National Security, Defence and Intelligence — the kind of place where the work genuinely matters and the problems are genuinely hard. They've been doing this for over 70 years, but they've still got the energy and ambition of a company that's just getting started. Based in Gloucester, their engineering team is a mix of software engineers, data engineers, SREs and product specialists all working together on systems that operate in the most demanding environments imaginable. This is a collaborative, technically excellent team and they're growing — which is where you come in. To hit the ground running, you'll need solid hands-on experience with Java and Spring Boot, a background in big data engineering including Hadoop and large-scale data pipelines, and a working knowledge of Ansible for infrastructure automation. GitLab for source control and CI/CD is a must, and you should be comfortable applying SRE principles to keep production services reliable and performant.

 Sound like you? APPLY TODAY and let's get talking.
