Electronics Engineer (Avionics / Legacy Systems)

The Opportunity

An exciting opportunity has arisen for an experienced Electronics Engineer to join a specialist engineering team working on the maintenance, repair and overhaul of legacy avionics and electronic systems.

This hands-on role is ideal for someone with strong analogue electronics knowledge who enjoys fault finding at component level and developing bespoke testing solutions. You'll work on a wide variety of complex electronic assemblies, playing a key role in supporting repair activities while helping to improve engineering processes and testing capability.

Key Responsibilities

Fault Diagnosis & Repair

• Diagnose and troubleshoot faults on analogue avionics systems and electronic assemblies.
• Carry out component-level repairs including PCB fault finding, soldering and rework.
• Repair wiring, connectors and associated electronic assemblies.
• Replace obsolete or failed electronic components where required.
• Work on a range of legacy systems including:
  • Flight instrumentation
  • Control units and panels
  • Navigation and gyroscopic equipment
• Apply first-principles fault-finding techniques where technical documentation is limited or unavailable.

Test Equipment Design & Validation

• Design and develop bespoke test equipment and test rigs to support repair activities.
• Define test methods, architecture and acceptance criteria.
• Build, commission and maintain test equipment using appropriate instrumentation.
• Validate repaired equipment against functional and performance requirements.

Circuit Analysis & Reverse Engineering

• Analyse analogue circuits to understand functionality and identify failure modes.
• Interpret circuit diagrams, wiring schematics and technical manuals.
• Reverse engineer electronic assemblies where documentation is incomplete.
• Reconstruct system functionality to support repair and testing activities.

Documentation

• Produce detailed engineering documentation including:
  • Strip and build reports
  • Test procedures
  • Fault reports
• Develop test plans where OEM documentation is unavailable or insufficient.
• Ensure all engineering work is fully documented and traceable.
