We are seeking a Satellite Electrical Power Systems Engineer to lead the design, development, and delivery of the electrical power subsystem for our satellite missions. You will own the end-to-end power system architecture — from energy generation and storage to power conditioning and distribution — ensuring reliable, efficient operation throughout the mission lifecycle.
Key Responsibilities
Define and maintain power subsystem requirements, architecture, and interface control documents (ICDs).
Design and analyse solar array, battery, and power regulation/distribution systems to meet mission needs.
Conduct power budget analysis and sizing for all mission phases, including contingency scenarios.
Perform modelling, simulation, and worst-case analyses to verify system robustness.
Select and qualify components for ULEO space environments, including radiation tolerance, atomic oxygen exposure, and thermal considerations.
Support manufacturing, assembly, integration, and testing of the power subsystem.
Develop and execute subsystem-level and integrated system-level test plans (functional, thermal vacuum, vibration).
Lead power subsystem reviews (PDR, CDR, TRR) and support system-level design and readiness reviews.
Interface with all spacecraft subsystems and engage in system-level trade-studies.
Support launch and early orbit operations, including on-orbit power performance monitoring and troubleshooting.
Fundamental Requirements
>3 years of experience in spacecraft or satellite power subsystem engineering, with at least one smallsat-class mission delivered to orbit.
Strong technical knowledge of spacecraft electrical power systems, including solar array design, battery technology, and power electronics.
Experience with power budget modelling, simulation tools, and hardware test campaigns.
Familiarity with space-qualified components and radiation/thermal design considerations.
Hands-on experience in integration & testing in cleanroom environments.
Excellent problem-solving skills and the ability to work in agile, cross-disciplinary teams.
Strong communication skills to work with suppliers, subsystem teams, and mission partners.
