AIT Technician F/M, Massy

About Exotrail Born from a strong ambition to reach for the stars, Exotrail is a fast‑growing scale‑up founded in 2017. Its mission: to develop and commercialize propulsion systems for small satellites on a global scale.

We design products focused on impact, fast delivery, and continuous improvement. Inspired by the digital world, we are firmly customer‑oriented and driven by an entrepreneurial spirit.

We manage risks to push boundaries and achieve results that would not be possible within a traditional space model.

We deploy every necessary resource to support the development of our products, whether in propulsion or in‑orbit services. Strengthened by an innovative mindset inherited from our early days, we are preparing to grow into an ambitious industrial company.

Job Description We are looking for a

Senior AIT Technician

at our

Massy

site.

You will join the

AIT department

of our In‑Orbit Services Business Unit. As a senior technician, you are the technical reference operator of the production line: you perform physical integration operations on spacevan™ satellites in an ISO 8 cleanroom, apply and transmit standards, and ensure full traceability of your work. You will interface directly with AIT teams (AIT Manager, AIT Engineers, Test Manager), Engineering (System, Avionics, Mechanical‑Thermal, IV&V– Independent Verification and Validation) and Quality (PA/QA).

Beyond technical skills, we are looking for someone

rigorous, autonomous and reliable , capable of working on flight hardware with a constant focus on execution quality and traceability.

Your main tasks and responsibilities will be:

Perform mechanical and electrical integration operations : Carry out integration operations in cleanroom (structural assembly, equipment installation and fastening, harness routing and connection, electrical and RF connections, MLI, SSM, heaters installation, bonding, torquing). Perform in‑house PCB assembly operations according to defined assembly work packages. Rigorously apply ISO 8 cleanroom rules, ESD (Electrostatic Discharge), chemical and fluidic safety procedures.

Prepare and execute procedures with full rigour : Prepare operations from defined procedures and work packages. Respect quality hold points, ensure full traceability of operations in as‑built manufacturing records (photos, as‑run records, logbooks), and systematically report any deviation or non‑conformance observed to the AIT Engineer.

Perform quality controls and inspections : Carry out compliance checks and visual inspections at each critical step (incoming, hold points, final configuration). Fill in associated check‑lists and records with full rigour. Document NCRs (Non‑Conformance Reports) and actively contribute to first‑level investigations.

Ensure traceability and documentation : Maintain full traceability of every operation in ERP (Odoo) and manufacturing records: hardware configuration, software version, datasets, logs. Contribute to field lessons learned reporting to the AIT Engineer and the Industrialisation&Methods team.

Support campaigns and contribute to team upskilling : Support the AIT Engineer during functional test and verification phases (EGSE bench connection, test sequence execution per procedures, TM/TC parameter monitoring). Participate in off‑site campaigns depending on seniority. Ensure cleanliness, compliance and safety of work areas (5S). Contribute to upskilling future junior technicians.

Preferred Experience

Education: technical qualification in mechanical engineering, electrical engineering, electronics or equivalent field.

Experience: 7+ years of AIT experience on satellites or space subsystems in cleanroom. Direct

experience on flight hardware (FM)

is mandatory. Confirmed autonomy on physical integration operations.

Tools proficiency:

Integration and tooling : torque wrench, torque tightening and mechanical alignment tools, MGSE (Mechanical Ground Support Equipment), electrical measurement and dimensional inspection tools

AIT documentation : manufacturing records, check‑lists, NCR, as‑built, logbooks; practice of ERP/Odoo for operation traceability.

Knowledge:

Satellite system architecture

(structure, thermal, avionics, power, propulsion, communications) and AIT integration processes and procedures.

Reading

complex mechanical and electrical drawings .

AIT documentation rules : generating manufacturing records, check‑lists, NCR, as‑built, logbooks.

Installation constraints on environmental test means: vibration table, TVAC (Thermal Vacuum) chamber, anechoic chamber, acoustic test trolley.

Hardware constraints

of MGSE and EGSE; ESD knowledge and associated protective equipment.

Applicable standards: ECSS (E‑ST‑10, Q‑ST‑70, Q‑ST‑20) and NASA NPR. ISO 8 cleanroom procedures, ESD, chemical and fluidic safety.

B1V/BE electrical clearance , crane operator clearance (CACES R484) and aerial work platform clearance (CACES R486) appreciated.

Nice to have: background in functional testing (EGSE connection, test sequence execution, TM/TC monitoring), embedded electronics (wiring, continuity, space connector identification) or AIT quality control (internal AIT QC clearance) significantly broadens your scope with us– a discriminating criterion at this stage of our development.

Soft skills: execution

rigour

and zero‑defect culture on flight hardware;

method and attention to detail

in documentation; field

autonomy

with good collaboration skills; ability to pass on best practices to junior technicians.

Fluent in French and English (clear technical communication).
