Satellite AIT Electrical Systems Engineer

Job Summary

Preparation of test procedures, writing and debugging test sequences for Satellite system testing during ambient and environmental test campaigns. Preparing, debugging and executing complex test sequences on flight spacecraft and test benches. Providing first-line support to the test operations team and supporting non-conformance reviews in a technical capacity. Writing test reports and supporting test reviews.

Job Profile

• Interpretation of electrical and functional test requirements from test specifications.
• Provide test solutions to meet the test specification requirements, from planning and kick-off meeting, through test sequence coding, procedure preparation and debug to execution.
• Provide first-line support to the test operations team executing tests on the flight spacecraft in the event of anomalies.
• Close out tests with Post Test Review and Test Report.
• To provide technical inputs to project test reviews (Test Readiness Reviews, Post Test Reviews, Test Review Boards and Non-Conformance Review Boards).
• Development and debug of Automatic Test procedures (ATP) using a bespoke high-level S/W language (Open Center checkout system based on the Elisa language and Open Center Bridge based on JAVA) to test the spacecraft systems.
• Preparing and executing spacecraft system investigations in line with actions from Non-Conformance Review Boards (NRBs).
• Support Spacecraft systems functional and performance tests during environmental tests (TVAC, Magnetic, EMC).
• Work to company and departmental procedures and maintain adherence to company standards.

Knowledge, Skills and Experience

• Current hands-on experience of writing test sequences/scripts for execution of spacecraft tests from the Central Checkout System (CCS). Knowledge of Elisa and JAVA would be an advantage.
• Working knowledge of TMTC Databases.
• Spacecraft systems and subsystem technical knowledge and awareness is essential, e.g. Data Handling, Packet Utilisation Standard, Data Bus Communications - 1553, Spacewire, Attitude & Orbital Control, Star Trackers, Gyros, Momentum Wheels, power systems, batteries, Solar Arrays, Thermal Control, heaters, thermostats, FDIR, Spacecraft Configuration Vectors etc.
• Programming and scripting languages, particularly writing and debugging Linux/Unix bash scripts is an advantage. Knowledge of a programming language such as C, Java, Python, TCL, VBA would be useful but not essential.
• Competent in the use of various test equipment used for electrical measurements, e.g. DMM, oscilloscope, current probes, Data acquisition unit, data bus monitors (1553 MilBus and SpaceWire probes/analysers) would be an advantage.
• Spacecraft electrical and harness knowledge would be an advantage but not essential.
• Familiar with the Windows and Linux operating systems.
• Awareness of 'cleanroom' disciplines.
• Knowledge of system testing & Verification.
• Willing to support shifts/flexible working as required.

Experience

• Writing test sequences/scripts for execution of spacecraft systems tests including FDIR from the Central Checkout System (CCS).
• Electrical/Spacecraft Systems fault investigation and test sequence debug.
• Environmental and launch test campaigns.
• Preparing test procedure and sequences from test specifications, writing test reports and supporting test and non-conformance reviews.
• Electrical integration of equipment on a test bench or spacecraft (desirable, not essential).
