Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Systems Engineer - SmallSat Missions - **Company:** Xperior Global - **Location:** Aylesbury, UK - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** Systems Engineering, Confluence, JIRA, Software Documentation, Network Interface Controllers, Failure Mode Effects Analysis, Systems Architecture - **Published:** September 9, 2026 - **Apply:** https://www.collegerecruiter.com/job/2850548000-systems-engineer-smallsat-missions ## About the Role We're looking specifically for someone who has already developed experience within Satellite Systems Engineering, rather than someone looking to transition from Mission Analysis or another unrelated space discipline., * A minimum of approximately 2-3 years of directly relevant Satellite Systems Engineering experience. * Experience working at spacecraft/system level, with an understanding of how multiple satellite subsystems interact. * Exposure to spacecraft architecture definition and system-level engineering decisions. * Experience evaluating, selecting or integrating spacecraft subsystems and/or equipment. * Experience working technically with external subsystem or equipment suppliers. * Understanding of spacecraft requirements, interfaces and technical trade-offs. * Exposure to satellite verification, integration, AIT/AIV or qualification activities. * Understanding of the complete spacecraft development lifecycle. * A degree in Aerospace Engineering or a related technical discipline., Experience in any of the following would be beneficial, but we are not looking for a specialist in one particular spacecraft subsystem: * ESA / ECSS standards * Interface Control Documents (ICDs) * Configuration and change management * Verification Control Documents * FMEA / FDIR * Electrical Power Systems (EPS) * Thermal systems * AIT / AIV * Launch campaigns * Jira, Confluence, Valispace or similar systems engineering tools, For someone with a few years of Satellite Systems Engineering experience, this provides an excellent opportunity to broaden their spacecraft-level technical responsibility and continue developing towards more senior Systems Engineering and System Architecture positions., Candidates should therefore either already live within a reasonable commuting distance or be willing to relocate closer to the area. ## Description As a Satellite Systems Engineer, you'll work closely with senior engineers and the System Architect across the technical development and delivery of SmallSat missions., * Supporting the definition and development of spacecraft system architectures. * Evaluating and supporting the selection of satellite subsystems from external suppliers, including technical trade-offs between potential solutions. * Defining and tracking technical requirements and interfaces between spacecraft subsystems. * Supporting the management of interfaces across Space, Ground, Launch and User segments. * Establishing and maintaining the system technical baseline, including configuration changes, anomalies and non-conformances. * Maintaining and supporting the Verification Control Document (VCD). * Supporting AIT, AIV, verification and qualification activities at system and subsystem level. * Contributing to technical analyses, trade-off studies and risk-management activities including FMEA and FDIR. * Producing and maintaining technical specifications, interface documentation and spacecraft user documentation. * Supporting spacecraft integration and, where required, launch campaign activities. ## Related Videos -
