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.
