Ait engineer - test & automation

À propos de Exotrail A propos d'Exotrail Née d’une forte ambition de conquérir les étoiles, Exotrail est une « scale-up » fondée en 2017. Sa mission : développer et commercialiser des moteurs pour petits satellites à l’échelle mondiale. Nous concevons des produits axés sur l’impact, la livraison rapide et l’amélioration continue. Inspirés par le monde du digital, nous sommes résolument tournés vers le client et portés par un esprit entrepreneurial. Nous gérons les risques pour dépasser les frontières et obtenir des résultats qui ne seraient pas possibles dans un modèle spatial traditionnel. Nous mobilisons tous les moyens nécessaires pour soutenir le développement de nos produits, qu’il s’agisse de propulsion ou de services en orbite. Forts d’un esprit d’innovation hérité de nos débuts, nous nous préparons à faire grandir une entreprise industrielle ambitieuse. Le poste We are looking for an AIT Engineer - Test & Automation at our Massy site. You will join the AIT department of our In-Orbit Services Business Unit. This role sits at the intersection of AIT operations, test software, and embedded systems: you will design, deploy and evolve the test automation architecture for current and future programs, with direct impact on production cadence and campaign reliability. You will interface with AIT teams (AIT Manager, Test Manager, Technicians), Engineering (System, Avionics, IV&V - Independent Verification and Validation), Mission and Quality (PA/QA), as well as external partners during campaigns (test centers, launch sites, bench suppliers). Beyond technical skills, we are looking for someone who can structure and industrialize, rigorous, autonomous in problem-solving, comfortable in a multi-program environment and in technical communication in French and English. Your main tasks and responsibilities will be: Develop, validate and maintain test automation solutions : Design and evolve robust test automation solutions covering the full validation cycle. Develop test scripts and frameworks (Python, TypeScript, internal tools), integrate them into CI/CD pipelines (GitLab CI, Jenkins), and guarantee their robustness, maintainability, traceability and reproducibility in a critical environment. Deploy and operate test means (EGSE) : Configure, qualify and operate test benches (EGSE, Electrical Ground Support Equipment), simulators and TM/TC supervision systems. Deploy automation solutions on these means and implement automated test campaigns (regression suites, overnight runs), ensuring hardware/software configuration consistency. Prepare, execute and analyze AIT test campaigns : Contribute to AIV/AIT campaign preparation by defining test sequences and associated configurations. Execute functional tests (power-on, mode transitions, RF/electrical/propulsive performance) and perform first-level analysis (anomaly triage, reproducibility checks, pre-diagnosis and structured escalation). Ensure test traceability and compliance : Guarantee requirements coverage through test activities, in line with IV&V (Independent Verification and Validation) strategy. Manage script configuration, test environments and associated data. Maintain rigorous test documentation (logbooks, tickets, reports, anomalies) in compliance with applicable quality and testing standards (ECSS, NPR). Structure and continuously improve test activities : Standardize automation methods and contribute to industrialized, reproducible test pipelines. Reduce campaign lead time and improve reliability (flaky test reduction, early anomaly detection). Contribute to technical investigations and lessons learned capitalization to improve overall AIT system performance. Profil recherché Education: engineering degree or equivalent in computer science, software engineering, embedded systems or electronics. Experience: 5 years in test automation, embedded or complex industrial environments. Experience in AIT, production or industrialization in the space sector or a high-reliability industry (aerospace, defence) is strongly valued. Tools proficiency: o Scripting and automation : Python (mandatory), TypeScript appreciated; CI/CD (GitLab CI, Jenkins); DevOps (Docker, Linux); Git versioning. o Test benches and EGSE : test bench architecture (HIL, simulators), TM/TC supervision; data and monitoring: InfluxDB, MongoDB, Grafana. o Embedded protocols (strongly valued): RS485, CAN, I2C, UART. o Protocols and interfaces (bonus): Ethernet TCP/IP, RF, MQTT, HTTP, Modbus, NATS. o T raceability and configuration : DOORS (requirements traceability), PLM (3DExperience or equivalent), GitLab/Jira, Odoo. Knowledge: o Satellite system architecture (ADCS, propulsion, avionics, power, communications, thermal) and IV&V logic (requirements coverage, as-run traceability). o Applicable functional test and configuration standards : ECSS (E-ST-10, E-ST-10-03, M-ST-40, Q-ST-20) and NASA NPR. o AIT environment constraints : ISO 8 cleanroom, ESD, B2V/BE electrical clearance appreciated. Soft skills: strong engineering rigour, ability to structure and industrialise processes, critical thinking and problem-solving, autonomous but team-oriented Fluent in French and English (clear technical communication).
