Job Description ‍

Position: AIT Engineer - Hardware and System Testing

Location: Exotrail's Massy office

Department: In-Orbit Services

Reports To: AIT Team Leader

Employment Type: Full-time

Exotrail seeks an AIT Engineer specialized in Hardware and System Testing for the SpaceVan project. This position focuses on testing spacecraft systems, particularly avionics and other electronics subsystem, to ensure compliance with mission requirements. As a critical contributor to the verification phase, you will design and execute functional and environmental tests, manage test data, and work closely with multidisciplinary teams on IVVQ (Integration, Verification, Validation, and Qualification) processes. Collaborative, problem-solving, and detail-oriented, you will help drive quality and efficiency across testing phases.

The current team comprises several AIT engineers and technicians across missions (LEO, GEO, Rendez-vous), and this role will support test phases for diverse mission types.

Your main tasks will be:

Test Planning and Preparation: Design and optimize testing workflows; create and refine test specifications and procedures for both subsystem and system levels, focusing on functional, environmental, and performance testing, with a strong emphasis on Integration, Verification, Validation, and Qualification (IVVQ) standards.

Test Scripting: Develop automated test scripts in Python and C/C++ to improve testing efficiency and support test data collection.

Test Execution: Conduct subsystem and end-to-end hardware tests, including avionics, power, propulsion, thermal, and electrical, across Engineering Models (EM), Qualification Models (QM), Flatsat, and Flight Models (FM) to validate performance and reliability.

Assembly and Integration support: Support assembly and integration tasks, including mechanical, electrical, and thermal integration of spacecraft subsystems. Follow established procedures to ensure that all connections and interfaces meet specified tolerances.

Documentation and Reporting: Document integration and test outcomes meticulously, including pass/fail criteria, observed anomalies, and test deviations, and log this data in our documentation and ticketing platforms.

GSE setup: Ensure proper setup and operation of Electrical and Mechanical Ground Support Equipment (EGSE and MGSE) for each testing phase.

Environmental Testing and Launch Support: Actively participate in environmental test campaigns, including vibration, thermal vacuum (TVAC), and EMC testing, and assist during launch campaigns.

Configuration Management: Ensure accurate configuration control of all testing hardware, tracking software versions and test equipment setups for each testing phase.

NCR and Troubleshooting: Generate Non-Conformance Reports (NCRs) for issues arising during AIT phases and collaborate with quality assurance and engineering teams to resolve these quickly and efficiently.

Best Practices: Capture and integrate lessons learned from each test cycle to continually refine and enhance future testing practices and workflows.

You will work under the supervision of the AIT Team Leader and maintain regular interactions with the cross-functional teams.

The position is opened in Exotrail's offices in Massy.
