AIT Electrical Engineer

Expleo is a trusted partner for end-to-end, integrated engineering, quality services and management consulting for digital transformation. We help businesses harness unrelenting technological change to successfully deliver innovations that will help them gain a competitive advantage and improve the everyday lives of people around the globe.

We are searching for an Electrical Engineer reporting to the Assembly, Integration and Test (AIT) Operations Manager and joining the AIT team. The Electrical Engineer will be office based responsible for the electrcial assembly, integration and functional/verification testing of satellites and their electrical/avionics subsystems.

The role will be based out of our Clients Stevenage site.

• The role is centred on the delivery of electrical AIT activities using the Central Checkout System (CCS5), spanning the authoring and execution of test procedures and automated test scripts, flight-hardware integration, test-harness design, EGSE/SCOE operation, anomaly investigation, and support to the environmental test and launch campaigns. The postholder will have the following responsibilities:
• Perform electrical/avionics system electrical integration and functional testing activities for satellite programmes.
• Develop, maintain and execute test procedures and automated test scripts on the Central Checkout System (CCS5), including sequence/TCL scripting run against the spacecraft reference database (MIB/SRDB) as well as bespoke company systems.
• Perform electrical AIT integration of flight hardware — units, harnesses and EGSE — under clean-room conditions.
• Interpret Interface Control Documents (ICDs) and translate electrical/interface requirements into integration steps and verifiable test cases.
• Design, specify and validate test harnesses, break-out boxes and interface adapters between EGSE/SCOE and flight hardware.
• Carry out testing and debugging at unit, subsystem and satellite level, isolating and characterising faults across electrical and avionics interfaces.
• Operate, configure and maintain EGSE and SCOE, including set-up, calibration checks and troubleshooting.
• Perform data interpretation (measurement and telemetry), assessment and analysis of integrated electrical/avionics systems.
• Use laboratory and RF/electrical test equipment — multimeters, oscilloscopes, signal generators, power meters, network analysers and data-bus monitors/analysers — for measurement, verification and fault-finding.
• Support the Environment Tests (EVT) and the wider electrical verification programme.
• Create technical documentation, including test procedures, test scripts, test reports and as-run records.
• Undertake work package management as required.
• Perform problem investigation for the resolution of non-conformances and anomalies (NCR / anomaly reporting and corrective action).
• Communicate risks, issues and solutions to peers with various technical backgrounds and areas of expertise.
• Participate in daily AIT meetings, TRR, TRB, NRB and similar reviews and boards.
• Support environmental tests (Thermal Vacuum, Vibration, Acoustic and EMI/EMC) at satellite level.
• Support the satellite launch campaign at launch sites.

• Degree in engineering with ideally electrical background.

• Test-harness design and electrical AIT integration, including interpretation of ICDs.
• Competent use of electrical/RF test equipment: multimeters, oscilloscopes, signal generators, power meters, network analysers and data-bus monitors.
• Procedure and test-report writing.
• Knowledge of spacecraft database management (MIB / SRDB) would be an asset.
• Knowledge of a coding language (TCL, and/or Python) for test automation would be an asset.
• Familiarity with ECSS standards and conventions.

• Experience of EGSE/SCOE design or operation.
• Experience of supporting a launch campaign would be an asset.
• Hands-on experience with the Central Checkout System (CCS5) — test procedure development, test-script authoring and test execution.
• Experience in satellite avionics and databus protocols.
• Experience of flight-hardware integration and testing.
• Proven experience of working in a satellite assembly, integration and…
