Test Systems Engineer – GCAP (Hybrid) in Southampton

Would you like a once-in-a-generation opportunity to play a fundamental role in a Defence programme of critical National and International importance, and to help shape the future of Combat Air capability in the UK? The Test Engineer role is a new and exciting one within the Test Environments area of the Future Combat Air Line of Business that will enable Leonardo to meet the challenges of a highly successful and growing business. The role will provide focus on delivering a robust and effective test capability (rigs, full integrated test solutions at all levels, bespoke software development and Test frameworks) in support of the Global Combat Air Programme (GCAP). GCAP will deliver Tempest, the 6th Generation fighter aircraft that will replace the Royal Air Force Typhoon fleet, in the 2035 timescales. Given the nature of the work at this level, we are able to offer some hybrid working, however on-site working is expected for the purposes of collaboration and secure working. Due to the international scope of GCAP, the successful candidate will also have the opportunity to travel overseas to work with colleagues in Italy and Japan.

Your impact

As a Test Engineer within the Test Environments area of GCAP, you will:

• Provide Test Engineering expertise across many areas of Test Environments including Physical development, Digital development and Real-World application of test capabilities, working with Systems Engineers and other team members to develop a holistic set of test solutions.
• Develop a range of Physical and Synthetic Test Solutions across different levels, to include SRI/LRI, Bench Level integration, Full Systems Integration, Hardware in the Loop and Simulation modelling.
• Gather input from the technical development stakeholders in order to capture their Test Environment requirements in support of the wider programme’s Test, Evaluation and Acceptance Plans, working to define schedules, dependencies, constraints and opportunities.
• Represent Leonardo as a SME for Test Engineering within Test Environments and provide support to industry engagement across GCAP on the wider Test Strategy topics.
• This includes liaising with international and UK stakeholders to discuss and influence future ways of working on GCAP for Test Environments.
• Work with the team to support a range of synthetic environment trials and enable exploitation into airborne trials, working with stakeholders, including but not limited to Procurement, Future Factory, IT, and many more.
• Bring Test Engineering expertise to bear to implement and deliver Test Environments (processes, methods, tools, technology, people) into GCAP using a systematic approach.
