Overview

Our customer, a large defence organisation, is seeking an experienced Electronic Systems & Sensors Engineer to provide engineering expertise in support of the Position, Navigation & Timing (PNT) Programme and Operation Scorpius.

The role will focus on electronic systems engineering, technical requirements, engineering documentation, risk management, subsystem design and the testing, verification and validation of electronic systems and sensors.

Team Context

The role sits within the Space Delivery Team, supporting the PNT Programme. The programme delivers a range of PNT projects and provides specialist advice and guidance on PNT best practice across defence, while also supporting Operation Scorpius activities.

Key Responsibilities

• Manage the generation of Electronic Systems & Sensors (ESS) requirements, defining technical deliverables and artefacts and updating documentation for subsystems, including consideration of in-service support and associated costs.
• Verify and recommend the use of technical data to support the management and maturity of engineering documentation, focusing on successful technical outcomes.
• Act upon identified risks, including safety, environmental, support and financial risks, applying the principles of risk escalation and risk transfer.
• Manage the design of a subsystem, component or process that meets customer requirements within realistic constraints of time, cost and performance.
• Participate in and scrutinise the system’s ESS testing, verification, validation and evaluation processes.

Essential Qualifications, Skills and Experience

• A Science, Technology, Engineering and/or Mathematics (STEM) qualification at RQF Level 4 or above.
• Experience providing technical advice and delivering successful electronic systems and sensors or mechatronic engineering outcomes.
• Technical experience in electronic systems and sensors or mechatronics across a variety of contexts.
• Professional registration with a relevant professional body or institution as one of the following:
  • Engineering Technician (EngTech)
  • Registered Science Technician (RSciTech)
  • Marine Technician (MarTech)
  • Registered IT Technician (RITTech)
  • ICT Technician (ICTTech)
• Alternatively, candidates without professional registration must hold a minimum RQF Level 6 qualification in a Science, Technology, Engineering and/or Mathematics discipline.

Desirable Skills and Experience

• Broad experience providing technical advice and delivering successful outcomes relating to Position, Navigation & Timing (PNT) technologies and/or Global Navigation Satellite Systems (GNSS).
• Experience working in a fast-paced delivery environment.

Additional Information

• Hybrid working, with attendance at Abbey Wood, Bristol, anticipated 2–3 days per week.
• Some off-site travel may be required.
• SC clearance required.
• UK nationality is desirable but not essential.
• Contract runs from ASAP to 31 March 2027.
