Mobility solutions for an agile space

Set-up of an operations software with a spacecraft simulator


Exotrail is a space company based in France. We are developing mobility solutions for an agile space.

Our mission is to allow small satellite constellations to move in space, so that we can optimise their deployment, increase their performances and reduce space pollution. Thanks to this, a new world of telecommunication, Earth observation and space exploration will arise.

Our mobility solutions range from highly flexible high-thrust propulsion systems for small satellites (ExoMG™), mission simulation and operation software (ExoOPS™), and orbital transfer vehicles (SpaceVan™).

Exotrail launched in 2017 and has secured over 20M€ from prestigious Venture Capital funds and public grants. Our team consists of 47+ people who are passionate about disrupting the space industry. We operate out of two locations: Toulouse and Massy (suburb of Paris).

This is only the beginning. Small satellites equipped with propulsion will be able to deliver new space services and will entirely disrupt the space industry by servicing, repairing, assembling and manufacturing spacecrafts directly in orbit. Join us and be part of our great ambition!

Job Description

Exotrail is looking for an intern in Software Development or Space Mechanics to integrate our operations software with Kerbal Space Program. ExoOPS™ is a software suite to design and operate satellite missions with an emphasis on propulsion operations.

ExoOPS™ is based on modern languages (Java and Javascript) and is targeted to satellite integrators and operators. Our main goal is to provide an easy-to-use, yet accurate and powerful tool for satellite integrators to design their platform with respect to mission and space dynamics constraints, and for operators to operate effortlessly constellations of satellites equipped with propulsion.

The use of an external simulation environment is important on two points. This brings us the capability to interface our software with solutions developed by others so it is a powerful communication tool. Also, using a complete spacecraft simulator, it can be used to simulate the real operations with a satellite with uncertainties and a complete system (power, attitude control, etc.).

Our core competencies lie in the development of algorithms to control low-thrust propulsion on small satellites and to integrate a full flight dynamics system within an easy-to-use, modular interface.

Among our team of engineers and in the lively city of Toulouse, France, your job will be to link ExoOPS™ with an external spacecraft simulation software, and to use it as a space environment simulator:

  • time management,
  • spacecraft model visualization,
  • telecommand sending,
  • telemetries receiving,
  • models matching,
  • API management.

This a unique opportunity to combine programming, space mechanics and space industry software development.

Preferred Experience

  • Technical profile in a software development or aersopace engineering track leading to a MSc in Software Development or Aerospace Engineering or the equivalent. Ideally the internship must be during a gap year or be the final internship before graduation.
  • Significative experience in Javascript, Python and C# languages.
  • Very good soft and presentation skills (technical documentation, assumptions, oral presentation). You must be able to work with a great autonomy.
  • English proficiency and a basic French level.
  • Strong reporting and organizational capabilities, and a desire to work with a very dynamic and ambitious team

You should be passionate about the space sector and entrepreneurship and ready to work in a very demanding environment – with the immense reward of being directly part of a very ambitious project!
