Test Engineer (GNC)

France
Full-Time

TLDR

Design and operate testbeds to validate sensors and actuators, ensuring flight hardware meets performance requirements in a fast-paced startup environment.

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!   E-Space is bridging Earth and space to enable hyper-scaled deployments of space-powered Internet of Things (IoT) solutions and services. We are fundamentally changing the design, economics, manufacturing, coverage limitations and service delivery associated with traditional satellite and terrestrial IoT systems.   By building a highly-advanced low Earth orbit (LEO) space system—with a unique antenna design, highly sustainable spacecraft system and low-cost, small portable end-user devices—we can extend global satellite coverage, capacity and connectivity beyond legacy space services to provide a new kind of IoT platform that lets users sense, track, connect and act on information gathered, anywhere.   We’re intentional, we’re unapologetically curious and we’re 100% committed to saving space, protecting our planet and turning connectivity into actionable intelligence. What you will do:

  • Test Bench Development — Design, build, and commission test benches and Ground Support Equipment (GSE) for GNC hardware validation, including mechanical fixtures, electrical harnesses, test PCBs, and other custom instrumentation. 

  • Review, inspect, and functionally test incoming electronic boards and assemblies: verify board bring-up, debug anomalies using oscilloscopes, multimeters, logic analyzers, and power supplies. 

  • Develop test software for GNC components (sensors, actuators), including automated test scripts, data acquisition, processing pipelines, and reporting tools. 

  • Develop and execute formal test procedures for component-level and subsystem-level validation, from first article inspection through production acceptance. 

  • Process, analyze, and document test results to support performance model updates, calibration, and design reviews. 

  • Participate in AIT campaigns, including environmental testing ensuring continuity from component validation through production. 

What you bring:

  • BS +5 years / MS +3 years in Electronics, Mechatronics, Aerospace, or related field. 

  • Minimum 3 years of professional experience in hardware testing, validation, or AIT in a space, aerospace, or high-reliability environment. 

  • Proficiency with Altium (PCB layout, design review) for test board and adapter development. 

  • Strong hands-on experience with lab instruments: oscilloscopes, logic analyzers, multimeters, power supplies, signal generators. 

  • Ability to read, interpret and build PCB schematics, identify failure modes, and debug board-level issues. 

  • Proficiency in Python, Unix/Linux/Bash, git-based workflows 

  • Experience handling sensitive electronics, optics, and mechanical hardware, including clean room practices and ESD protocols. 

  • Experience building and operating test jigs using Raspberry Pi, Arduino, or similar embedded platforms. 

  • Organized and proactive problem solver who thrives in a hands-on, fast-paced startup environment. 

Bonus points:

  • Knowledge of GNC sensors and actuators and associated test methods. 

  • Experience with spacecraft AIT and environmental testing (thermal vacuum, vibration, EMC). 

  • Familiarity with common spacecraft communication interfaces: SPI, I²C, UART, CAN, RS-422/485. 

While we welcome candidates with global experience, please note that English is the language we conduct our business in, and application submissions will need to be in English or both English and French to be reviewed by our global team.
