Overview
We are seeking a hands-on Senior Test Engineer to join our GNC Hardware team. You will design, build, and operate custom testbeds to validate sensors and actuators. Your ability to bridge hardware testing and electronic design will be central to ensuring flight hardware meets its performance requirements. This position is based in Toulouse, France.
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.

Overview
We are looking for a Senior Electronics Engineer to join our GNC Hardware team. You will design, develop, and validate electronic boards and power stages for compact, high-performance space mechanisms and assemblies. Your scope covers the full electronics lifecycle: from architecture definition and schematic capture through PCB layout, prototype bring-up, and qualification support. You will work at the intersection of power electronics, embedded systems, and mechanical integration in a demanding space environment.
What you will do:
-
Define the architecture of PCBAs for GNC hardware devices, including power conversion, motor drive stages, signal conditioning, and communication interfaces.
-
Perform schematic capture and detailed circuit design for power and mixed-signal boards.
-
Design multi-layer PCB layouts (including mixed-signals, DC-DC converters, H-bridge drivers, and current control loops) taking into account EMC, thermal management, and space-grade constraints.
-
Select and qualify PCBAs for space applications (radiation tolerance, derating, thermal, outgassing).
-
Produce thorough design documentation: schematics, BOMs, design justification files, and interface control documents.
-
Bring up prototype boards: power-on sequencing, functional verification, anomaly investigation and resolution.
-
Support test campaigns, including test board design, instrumentation, and data analysis.
-
Collaborate with the mechanical and test teams on integration, harnessing, and thermal interfaces.
-
Support environmental qualification activities (vibration, thermal, EMC).
What you bring:
-
BS +5 years / MS +3 years in Electrical Engineering, Electronics, or related field.
-
Minimum 3 years of professional experience in end-to-end PCBA design, production, and testing.
-
Proficiency with Altium Designer (schematic capture, multi-layer PCB layout, design rule management).
-
Solid background in power electronics (DC-DC conversion, motor drive topologies, current/voltage control loops) and analog/mixed-signal design (op-amp circuits, ADC/DAC interfaces, filtering, grounding strategies).
-
Experience with board bring-up, debugging, and validation using lab instruments (oscilloscopes, multimeters, power supplies, thermal cameras).
-
Familiarity with space or high-reliability electronics constraints: component derating, radiation awareness, thermal management, EMC design practices.
-
Autonomous, rigorous, and comfortable in a fast-paced startup environment.
