Senior Test Software Engineer

Based on site in Stevenage

Salary from £45,000 - £75,000 DOE + Bonus + 14% Pension + Paid Overtime

The software you write won’t sit behind a login screen.

It will configure, verify and validate complex defence systems. It will be used in development, production and field environments. It has to work. Every time.

You’ll join a multi-disciplined engineering team building high-reliability test solutions that sit between hardware and mission-critical systems. This isn’t feature development. It’s engineering with consequence.

You’ll be:

  • Writing robust software in C/C++
  • Developing high-performance test applications integrated with real hardware
  • Working closely with Systems, Electronics and Test teams
  • Solving problems that don’t stop neatly at the edge of “software”

If you enjoy writing clean, documented, dependable code and you like understanding how the whole system works, not just your module, you’ll fit well here.

What you'll bring:

  • Strong C / C++ experience
  • Previous software engineering experience in the development of test solutions
  • A good understanding of automation, continuous integration and DevOps principles and practices
  • Knowledge of electronics measurement and debug techniques using equipment such as oscilloscopes and spectrum analysers
  • Analytical thinking
  • Comfort working in safety or mission-critical environments
  • British citizenship or Dual national with British citizenship for security clearance

This is engineering that directly supports national capability.

If you want your work to mean something, let’s talk.

Where to Advertise Cloud Computing Jobs in the UK (2026 Guide)

Where to advertise cloud computing jobs UK in 2026: the specialist boards and channels that reach AWS, Azure, GCP and cloud-native engineering talent. The candidate pool is large relative to other deep tech disciplines but highly segmented — cloud architects, DevOps engineers, platform engineers, FinOps specialists and cloud security professionals each occupy distinct communities with different job search behaviours, certification profiles and salary expectations. General job boards reach a broad audience but struggle to differentiate between these disciplines, producing high application volumes but low candidate quality for specialist cloud roles. This guide, published by CloudComputingJobs.co.uk, covers where to advertise cloud computing roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Cloud Computing Jobs UK 2026: What to Expect Over the Next 3 Years

Cloud Computing Jobs UK 2026: salaries, hiring trends and the AWS, Azure and GCP skills shaping UK cloud careers over the next three years. Cloud computing is the infrastructure layer on which the modern digital economy runs — and the jobs market that has grown around it is one of the largest, most sustained, and most structurally resilient in the entire technology sector. But the cloud computing jobs market of 2026 looks quite different from the one that existed three years ago, and the next three years will bring further change at a pace that rewards those who understand the direction of travel. The migration phase that defined cloud hiring for much of the previous decade is largely complete for enterprise organisations. The question for most UK businesses is no longer whether to move to the cloud but how to operate, optimise, and secure what they have already built there — and how to integrate the wave of AI capability that is now being delivered primarily through cloud infrastructure. That shift has profound implications for which cloud skills are in demand, which roles are growing, and which are beginning to plateau. At the same time, new architectural patterns — multi-cloud, cloud-native, serverless, and the growing integration of edge computing with centralised cloud infrastructure — are creating entirely new categories of specialist expertise that employers are actively competing to hire. The cloud computing jobs market of 2026 is not contracting. It is evolving, and evolving in ways that create significant opportunity for job seekers who are building the right skills. This article breaks down what the UK cloud computing jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
