As a key member of our Avionics Team you will be responsible for the power subsystems for existing developments, from design to procurement and integration, and drive our spacecraft power designs for the future.
Responsibilities
System Engineering
- Provide power subsystem engineering, both high level architecture and detailed electronics design, from specification to integration
- Act as the technical point of contact on the Avionics subsystem with key stakeholders: internal project teams, customers, subcontractors.
- Perform requirements engineering (analysis, flow-up and down) related to spacecraft power systems, and the power interfaces of other on-board hardware
- Develop and maintain power subsystem architecture for missions
- Maintain spacecraft power budgets and parametric models for the power subsystem
- Analyse EMC constraints for power subsystem and identify mitigation measures
- Support the definition of power related test equipment
- Define validation, verification and test plans
- Support integration and test of power subsystem, including generation of reports
- Support flight operations
- Generate documentation for the full project lifetime (e.g. Design, Development and Verification Plan; FMEA; design review documentation; in-orbit subsystem operational procedures)
- Support to customer and project reviews
Unit definition and procurement
- Write and support Requests for Proposals (RFPs) to external companies for avionics units reviewing responses and supporting‑down selections
- Provide subcontractor management and technical supervision for key hardware deliverables, both power units and supporting other avionics procurements
- Review and assess power electronics aspects of all spacecraft equipment supporting other disciplines
Internal developments
- Support architecture and product development for future spacecraft power systems
- Contribute to detailed power electronics design for in-house developments
Must Have
- BSc/MSc Degree in Power management, Electronics, Aerospace, Physics or similar
- 5+ years Power System and Electrical Engineering experience in a systems or power electronics role
- Experience of power electronics/subsystems in the space industry, including power conditioning and distribution, DC/DC converters, solar arrays, solar array regulation and drive mechanisms, battery management (battery charge/discharge regulators)
- End to end mission experience working as an Avionics engineer for space systems, performing design and analysis.
- Ability to work in a team and willingness to collaborate outside your immediate expertise
- Strong communication and analytical skills
- Knowledge of typical program lifecycles, with previous experience as an active contributor to key formal reviews (MDR, PDR, CDR, etc)
- Experience with spacecraft implementation phases to launch
Nice to Have
- Experience of Avionics & Spacecraft electrical systems beyond the power subsystem
- Detailed understanding of power electronics analysis, design, build, and test
- Understanding of actuator and motor drive electronics
- Hands‑on electronics design and test experience, including fault diagnosis
- Experience with common space standards (ECSS, MIL, etc), and associated tailoring
