Senior Avionics Engineer

At UNIVITY, we believe that everyone on Earth should have access to internet connectivity. 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. Our next major milestone will be 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. The 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. Senior Avionics Engineer – Toulouse Office

Reporting to the Program Manager, the Senior Avionics Engineer will play two major key roles: Implement and guarantee the avionics validation and integration for the two demonstrators uniShape. Define the complete avionics architecture for the constellation uniSky until industrialization, launch and deployment of the constellation, focusing on design to cost, design to industrialization, design to performance. The engineer 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, the engineer will contribute to the design, development, integration, and validation of high‑performance avionics systems for next‑generation space missions. Key Responsibilities

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 and 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 cost, industrialization and performance. Review and select potential suppliers for various equipment. Specify, develop and validate associated software. Prepare and support avionics operations throughout development, integration and testing phases. Coordinate activities of functional validation, flatsat setup, embedded software 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. Requirements

Skills and Experience

Minimum master’s degree in aerospace engineering, electronics engineering, embedded systems or a related discipline. Minimum 7–10 years of experience in spacecraft avionics or complex embedded aerospace systems. Strong knowledge of satellite avionics architectures and spacecraft subsystems. Proven experience with AOCS, DHS and TT&C systems. Experience writing system requirements and functional specifications. Familiarity with satellite development lifecycle, including AIT activities. Experience working with external suppliers and multidisciplinary engineering teams. Excellent analytical, communication and leadership skills. Nice to Have

Experience with New Space programs. Knowledge of ECSS standards. Experience leading small engineering teams or technical work packages. Excellent written and oral communication skills in French and English. 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.
