At CONSTELLATION TECHNOLOGIES & OPERATIONS we believe that everyone on Earth should have access to internet connectivity and we are on a mission to empower telecom operators to deliver high-performance, affordable, sustainable internet from space to their clients where terrestrial networks are not available.

We will launch our first mission in 2025. This Early Test is dedicated to validating the core technology that will enable broadband internet transmission from space. The Early Test will pave the way for our next major milestone: an in-orbit demonstration in late 2027, where two complete satellites will be deployed to further validate the system end-to-end. The following step will be to deploy our full constellation of disruptive satellites, enabling telecom operators to provide seamless connectivity worldwide.

Our project is rapidly ramping up, and we are looking to expand our team with passionate individuals who share our vision.

CONSTELLATION was created in 2022 and has offices in Toulouse and Paris. We offer exceptional learning and career development opportunities, as well as competitive salaries and benefits.

CONSTELLATION is looking for a Radio Frequency Intern to join the RF Technical team in our Toulouse office reporting to the Senior RF Engineer.

As a Radio Frequency Intern, you will be responsible for designing fundamental RF building blocks (RF filters, RF transitions, RF dividers…) using simulation tools such as CST. These designs will then be integrated into our RF equipment that will be used in space. A part of your project will be a key component of our constellation, giving you the unique opportunity to contribute to cutting-edge technology.

Your key responsibilities and tasks:

• Conduct literature review and perform trade-off analysis of available topology.
• Develop your understanding of the CST software.
• Design RF blocks such as RF filter, using CST based on specifications from the RF team.
• Identify potential industrial partners for prototype development and oversee production.
• Test and validate prototypes in the on-site development lab.
• Correlate measurements with simulations.
• Write design rules and procedures for future use by the company.

Skills and experience

• Master's student (Bac+4/+5) in RF, microwaves.
• Good knowledge of RF circuits, wave propagation, and simulation tools such as CST.
• Experience with RF test equipment (spectrum analyzers, signal generators).
• Basic coding skills (Matlab, Python) are a plus.
• Independent, detail-oriented, and proactive.

People come in different shapes and sizes and it is difficult to write a job description for someone we have not yet met. Therefore if you are not sure that you meet all the criteria, or if you think that you may have something different to offer, we still want to hear from you.
