Wanna join the adventure?

The RF team at Loft Orbital designs and integrates antennas across frequency bands, from VHF to X-band, onto satellite platforms. Besides single antenna elements, the team also designs arrays for DOA-based RF emitter geolocation from LEO. Loft has already designed and manufactured L/S and S/C antenna arrays and now wants to support X-band. This is where you come in!

You will work closely with senior engineers from the RF team and propose new antenna designs for future missions. Based on papers available in the scientific literature and commercial EM simulation tools, you will have the mission to simulate and validate those antenna concepts. These tasks are critical to saving valuable engineering time for the RF team, and your contributions will directly impact the future of upcoming RF payloads.

Location: Toulouse office, city center (Jeanne d’Arc metro station)
Duration: 6-month, end-of-studies internship — target start date: early 2027.

About this role:

Conduct technology watch, market survey and state-of-the-art research X-band antenna (9-12 GHz) adapted to DOA applications
Design and synthesize innovative structures using tools such as CST.
Work with the RF team, the mechanicla team and the System Engineering team to develop new X-band antenna arrays.
Contribute to the integration of these antennas on Loft Orbital’s satellite platforms.
Learn and apply principles of RF and antenna engineering.
Help optimize antenna performance/placement with simulation software.
Write technical reports.
Actively collaborate with the team by sharing ideas and knowledge.
