Your impact

Are you a Systems Engineer who loves contributing to the UKs Defence Industry and making impactful change? We are recruiting for a number of Systems Engineering roles up to Principal level from a variety of backgrounds and skillsets, working on real engineering problems, designing and developing solutions that sit at the heart of our products. We have vacancies at both our Southampton and Basildon sites.

Our Systems Engineers span across range of activities that help pull together all the necessary engineering and technology strands into a high-performance system. As a Systems Engineer, you will bridge the gap between the theoretically possible and the practically implementable.

Typical work you might be involved in:

Contribute to an early concept study investigating the application of new technology on future platforms

Engage with stakeholders to define requirements for a new system

Design and integrate new functionality into an existing sub-system in Simulink

Collaborate with other engineers to design and prototype a detailed model of a system to understand observed simulated performance

Design and prototype algorithms in Matlab, taking into account limitations and constraints of the target hardware

Investigate the cause of anomalies observed during integration or evaluation activities, using real trials data

Activities covering all aspects of the Systems “V” diagram, including concepts, field trials and deployment

Developing cutting edge SW to counter threats to the platform from projectiles and drones autonomously

Mentoring and Coaching of other Engineers

Projects and area’s we work in range for applications within Naval, Land and Air. Technology includes:

Communications and Force Protection

EO/IR systems

What you’ll bring

Proven experience as a Systems Engineer within a working environment or advanced academic research experience is a must. Ideally, you will have a science-based Honours degree or equivalent experience.

We are not expecting you to have deep theoretical knowledge of radar, electro-optics or infrared systems, what we are looking for are Systems Engineers with applied engineering experience that we can build upon through training, team working and mentoring.

Domain specialisms include;

Digital signal processing

RF systems

Electro-optic systems

Multi-sensor data fusion and tracking

Data analysis using AI or Machine Learning

Operational Experience in Electronic Intelligence or Electronic Warfare

We are particularly interested in speaking to you if you have experience in any of the following areas;

Synthetic Environments

Verification and Validation

System of Systems

This is not an exhaustive list, and we are keen to hear from you even if you might not have experience in all the above. The most important skill is a good attitude and willingness to learn.
