Avionics Architect, Toulouse

Our mission is supported by an ambitious vertically integrated approach: design&manufacture of small satellites combined with development of earth observation services. Since its creation in 2018, the company has already grown substantially. Our team gathers more than 25 engineering expertise, from hardware design to software development&data science. In 2026, Aerospacelab counts offices in Louvain-la-Neuve (Belgium), Toulouse (France), Lausanne (Switzerland) and US West Coast with more than 350 full-time employees, with the ambition to position itself as the European leader in small satellites. Role overview

As an Avionics Architect, you will be a key technical authorityworking on satellite projects, responsible for defining and owning the end-to-end avionics architecture of our satellite, including platforms and payload.You will work at the intersection of hardware, firmware, and systems engineering, bridging functional requirements and physical implementation across multiple concurrent missions.The Avionics architect is involved during the full satellite development cycle, frommission analysis (typicallypower budget and data budget), satellitearchitecture designto satellite validation and supporting the satellite operators.At Aerospacelab, our motto is work hard, play hard. With strive to innovate, in a fun and inclusive work environment. We work in short cycles– no waiting for years before manufacturing and testing to get valuable feedback. Expect an exciting job, where you will learn constantly and contribute to building state-of-the-art designs, that will play a crucial role in our missions.Key activities

Lead architectural trade-offstudies andtechnical design choices, balancing performance, mass, power budget, reliability. Ensure inter-compatibility (data, power, EMC/EMI) of all satellite sub-systems. Collaborate with systems engineers to derive avionicsand sub-systemsrequirements from mission-level specifications and ensure full requirements traceabilitySupport satellite end-to-end validation&verification team Support satellite operators Establish avionics design standards, and architectural guidelines reusable across the platform family Drive architectural design reviews (PDR, CDR) and act as a technical reference point for internal and external stakeholders Must have
