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.

Conducting advanced research

Developing cutting\-edge propulsion technologies

Collaborating with cross\-functional teams

Main responsibilities:

Design, develop, and analyze advanced propulsion technologies, including prototype construction and validation testing under diverse operating conditions.

Plan and execute laboratory tests, analyze performance data, identify discrepancies, and implement corrective measures to optimize propulsion systems.

Research and evaluate innovative materials, manufacturing methods, and emerging technologies to enhance propulsion performance and reliability.

Prepare technical reports, research papers, presentations, and maintain comprehensive documentation of research activities, experiments, and project progress.

Drive innovation initiatives within the propulsion domain, contribute to new research concepts, and support patent applications and intellectual property strategies.

Preferred Experience ‍️

Education: PhD in electric propulsion, chemical propulsion, plasma physics, material science, or a related field

Experience: 3–5 years of relevant research experience gained through a PhD, postdoctoral work, or industry projects

Hands\-on experience with electric propulsion systems and laboratory environments, including vacuum chambers, oscilloscopes, diagnostics equipment, power supplies, and experimental setup integration.

Proficiency in data acquisition, test applications, and data processing tools such as Python, ideally MATLAB, and/or LabVIEW.

Strong analytical mindset with the ability to independently investigate, understand, and optimise experimental behaviour and propulsion system performance.

Excellent written and verbal communication skills in both French and English, including strong technical writing abilities and a passion for developing agile, high\-technology space solutions.
