We're building the UK's next generation engineering powerhouse, providing critical technology that strengthens national security and resilience.

We specialise in turning advances in sensing, AI, and communications into operational capability for the edge, where connectivity may be degraded or denied. Our work focuses on accelerating the deployment of technology, improving decision-making for frontline teams, and protecting people and critical assets in demanding environments.

Headquartered in Bristol, Rowden employs around 200 people and operates over 20,000 square feet of engineering and manufacturing facilities. We have a growing international footprint and are one of Europe's fastest-growing engineering businesses.

About the opportunity

We are hiring System Integration, Test & Verification & Validation (V&V) talent at several levels, from engineers running integration and test activity on live projects to principal and senior engineers who design the test and V&V strategy for complex programmes.

Rowden already has an excellent systems engineering team, and we already integrate and test complex edge systems. However, the scale, pace and complexity of what we need to prove is changing, and with it our demand for integration, test and V&V specialists.

Our systems bring together software, compute, networks, radios, sensors, user devices and increasingly autonomous behaviour. They have to work across denied, degraded, intermittent and low bandwidth networks, where system behaviour shifts as connectivity and available resources shift. Right now, too much of our test infrastructure gets rebuilt for each project. It is often bespoke, manual and hard to reuse, which slows everyone down.

So, we are investing properly in this area. The goal is a world-leading integration, test and V&V capability for edge information systems, built on reusable test and evaluation infrastructure rather than one-off rigs. This will enable us to integrate earlier, test far more often, reproduce failures in minutes instead of weeks, and explore how systems behave in conditions that are difficult or impossible to create in the real world, using simulation and automation as first-class tools.

Executed well, this will significantly speed up the time it takes to get technology into users' hands – and it will be more effective when it gets there.

Candidates must be eligible for SC clearance.

Who we're looking for

We are deliberately keeping this broad, because we need strength at every level.

Principal and Senior Engineers. People to lead integration, test and V&V on significant programmes, and to build the reusable test and evaluation capability the rest of the business will rely on. We want systems thinkers who can design the right V&V strategy for a project – deciding what needs proving, choosing the right methods (test, analysis, inspection, demonstration, simulation), and knowing how much evidence is enough – as well as engineers who are strong on the integration and test execution side: test automation, instrumentation, simulation and emulation environments, network impairment, hardware-in-the-loop, data capture and analysis. Either way, you will be hands-on and you will set the standard others follow.

System Integration & Test (SI&T) Engineers. People to run integration and test activity on live projects, get real systems working together, find the failures early and work to resolve them.

If you are strong but sit between these levels, apply anyway. We will work out the right shape together.

Current titles and years of experience matter less to us than what you can do. Tell us where you think you fit.

What you'll be doing

Depending on level, you will:

Understand complex systems in development and design the V&V and test regime to ensure rigour and repeatability for rapidly iterating systems. At senior levels, this includes deciding the right mix of methods - test, analysis, inspection, demonstration, modelling or simulation - for a given project, and developing approaches that can be reused across the Rowden portfolio.
Integrate complex systems made up of software, compute, networks, radios, sensors and user devices, then prove they work under realistic conditions.
Build reusable test and evaluation capability that works across projects.
Automate test execution, data capture and analysis so teams get fast, trustworthy feedback.
Set up simulation and emulation environments that let us explore system behaviour across contested and degraded networks.
Reproduce awkward, intermittent failures quickly, and turn them into regression tests that stay.
Work upstream with systems, software, hardware and product teams so testability and verifiability are designed in.
Contribute to a cross-Rowden method for capture and full lifecycle close of testing issues and defects, ensuring a closed loop process back into the design cycles.
Help set and raise the engineering standards for integration, test and V&V across the business.

You will keep learning here, but some things you should already bring:

Real experience integrating and testing complex, multi-disciplinary systems, ideally where software, hardware and networks all meet.
Strong test engineering fundamentals. You know how to decide what is worth testing, and how to prove something rather than hope it works.
For principal and senior roles, demonstrable experience designing a V&V or test strategy for a project or system – deciding what to prove, choosing appropriate methods, and knowing when evidence is sufficient – not just executing a plan someone else wrote.
For senior roles, demonstrable awareness of distributed communication systems. How they are deployed, how the trade-offs between different communications bearers & spectrums will affect performance.
Practical automation skills. Scripting and tooling, most likely in Python, plus CI pipelines, containers and version control.
Experience with test infrastructure of some kind: hardware-in-the-loop, simulation or emulation, network impairment, instrumentation, or automated test frameworks.
An instinct for reuse. You build tools other people can pick up.
Comfort with ambiguity and pace. Our programmes move quickly and the requirements do not always arrive neatly.
Clear communication with engineers, project teams and customers alike.

Desirable (not essential)

RF, comms, EW or sensing experience.
Defence (land, maritime or air), aerospace, space or other safety- or mission-critical backgrounds.
Autonomy and robotics.
Model-based systems engineering, or formal V&V in a regulated environment.

About you

You want to work on hard problems, at pace, with people who are very good at what they do. You would rather build something than inherit it. You are happy being told the current approach needs improving, because you will be one of the people improving it. And you care that what we ship actually works for the person using it at the far end of a bad network.
