Description du poste

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.

UNIVITY is looking for a Senior Avionics Engineer to join the team Toulouse office reporting to the Program Manager.

As Senior Avionics Engineer, you will play 2 major key roles in the company:

• Implementing and guaranteeing the avionics validation and integration for the 2 demonstrators uniShape.
• Defining the complete avionics architecture for the constellation uniSky until industrialization, launch and "mis en service" of the constellation focusing on Design to costs, design to industrialization, design to performance.

You will be responsible for the overall avionics subsystem, coordinating the avionics team, and ensuring seamless integration within the satellite system throughout both projects' lifecycle.

Working closely with multidisciplinary engineering teams and external suppliers, you will contribute to the design, development, integration, and validation of high-performance avionics systems for next-generation space missions.

Your key responsibilities and tasks:

Technical Leadership

• Drive the overall avionics validation of the demonstrators uniShape
• Define and drive the overall avionics development strategy for the constellation uniSky
• Design the overall avionics architecture, including:
  • Attitude and Orbit Control System (AOCS)
  • Data Handling System (DHS)
  • Telemetry, Tracking & Command (TT&C)
  • Interfaces with Power and Thermal subsystems.
  • CONOPS, FDIR
• Ensure system consistency and compliance with mission and satellite requirements.
• Write and maintain avionics system requirements, equipment specifications, and functional specifications.
• Animate co-engineering activities with potential functions or hardware suppliers optimizing 1) Costs, 2) Industrialization and 3) performances.
• Review and selection of potential suppliers for various equipment
• Specification, development and validation of the associated software
• Prepare and support avionics operations throughout development, integration, and testing phases.
• Coordinate activities of functional validation, flatsat setup, embedded SW development, satellite database maintenance, simulator development

Project Coordination

• Coordinate the activities of the avionics engineering team.
• Define priorities, allocate workload, and monitor progress to ensure project milestones are met.
• Collaborate closely with Satellite System Engineers and AIT (Assembly, Integration & Test) teams throughout the development lifecycle.
• Identify technical risks and propose mitigation plans.

Supplier Management

• Act as the primary technical interface with avionics equipment suppliers.
• Review supplier technical documentation and monitor design progress.
• Participate in technical reviews and ensure supplier deliverables meet project requirements.

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.
