Embedded Electronics / Spacecraft Avionics Engineer (M/F) à Verrières-le-Buisson, France

Founded in 2017, ThrustMe is a pionnering space technology company revolutionizing the space propulsion industry. We made history in 2019 and 2020 with the world’s first in-orbit demonstrations of iodine-fueled electric propulsion systems based on RF ion thruster technology. Today, we are the global market leader in electric space propulsion for satellites below 150 kg, with more than 250 ion thrusters operating in space and over 1,000 systems ordered. We are growing rapidly from 70 to over 100 employees, with a significant part of the team dedicated to developing, industrializing and mass-producing space propulsion systems based on new concepts.

Your role:

ThrustMe ThrustMe is looking for an Embedded Electronics / Spacecraft Avionics Engineer (M/F) with strong skills across the entire electronics development cycle, from circuit design through qualification.

This position is within the Innovation Team , where you will solve problems without established solutions, build and test your ideas, and use the results to improve designs. This requires creativity, sound engineering judgment and the ability to work independently when requirements are still evolving. This role suits an engineer who enjoys open-ended development. You will help define the approach to unfamiliar problems while following applicable engineering and test procedures.

You will develop embedded electronics for propulsion systems, where circuits must deliver high performance and reliability under the extreme conditions of space. You will take early prototypes through testing and refinement to flight-ready designs.

Main tasks and responsibilities

• Define electronics architecture and develop subsystems that meet electrical, thermal, electromagnetic compatibility and radiation tolerance requirements.

• Design analog, digital, power and sensor interface circuits, including schematics and PCB layouts, and support prototype manufacturing.

• Develop and debug embedded firmware for hardware control and testing.

• Perform circuit simulations and analyses to guide design decisions.

• Bring up and debug prototype boards, investigate failures and iterate through hands-on testing.

• Select components and coordinate prototype sourcing and fabrication with suppliers.

• Plan, execute and document development and qualification tests.

• Collaborate with the Product Team to turn validated prototypes into repeatable, production-ready designs.

Skills and qualifications

Required skills and experience

• Master's degree or equivalent in electronics, electrical engineering, embedded systems or a related field.

• At least 3 years of relevant industry experience.

• Experience taking embedded electronics through the full development cycle, from concept to tested hardware.

• Solid understanding of analog, digital, power and sensor interface electronics.

• Ability to develop and debug embedded firmware.

• Strong hands-on testing and debugging skills using laboratory instruments.

• Proficiency in schematic capture, PCB design and circuit simulation tools.

• Evidence of independently solving unfamiliar engineering problems and taking responsibility for the outcome.

Useful additional experience

• Space electronics development and qualification, including EMC testing and radiation effects on electronic components.

• Vacuum technology, fluidics, chemistry or precision mechanisms.

• Design for manufacturing and transition to production.

• Personal engineering projects or other hands-on work that demonstrates curiosity and initiative.

How you work ?

You turn ideas into working circuits and embedded systems. You know relevant design standards but can develop a sound approach when no established solution exists. You combine analysis with hands-on testing, question assumptions and refine your designs based on measurements. You work independently, seek input when needed and take responsibility for the hardware and firmware you develop.
