Telecommunications Payload Engineer

Overview

At UNIVITY 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 successfully launched our first mission in 2025. We are now on our way for our next major milestone: an in-orbit demonstration in 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. UNIVITY 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. UNIVITY is looking for a Telecommunications Payload Engineer to join the team in our Toulouse office, reporting to the Senior Telecommunications Payload Engineer.

You will participate in the definition, design and development of the payloads and all their subsystems, (including RF, processor, antennas, power and control), and be responsible for ensuring correct interfaces between the payloads and the platforms to guarantee that the requirements of the overall mission are met.
• Develop the requirements of our payloads, working closely with the platform team and mission team to ensure compatibility with the overall mission.
• Define and own subsystem technical requirements.
• Prepare technical analyses, simulations, reports, trade-offs and recommendations as necessary to drive the development of the payloads and support the Mission engineering activities.
• Review technical documentation from internal and external suppliers and participate in their project reviews.
• Perform payload prototyping activities, including test definition, supply chain identification, in-lab integration and test execution.
• Support the AIT and industrial activities after satellite design is completed.
• Support the LEOP and operations activities after satellite launch.

Qualifications

Skills and experience

• Minimum master’s level qualification in Engineering or a related discipline with at least 5 years’ experience of systems engineering for the space environment.
• Experience with telecommunications payload engineering including working with on-board digital signal processors, channelization, and beamforming; and assessing telecommunications payload performances including EIRP, G/T, C/I, and capacity.
• Familiarity with network telecom architecture, including physical, access, network layers, link budgeting is as advantage.
• Experience with broadband/backhauling NGSO constellations, electronically steerable antennas, optical inter-satellite links, analogue and digital beamforming, and beam hopping systems is as advantage.
• Excellent written and oral communication skills in English.
• Pragmatic, with strong problem-solving and critical thinking abilities.

People come in different shapes and sizes and it is difficult to write a job description for someone we have not yet met. 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.
