A fast-growing space technology company is seeking a Satellite Electrical Power Systems Engineer to lead the design, development, and delivery of the electrical power subsystem for advanced small satellite missions operating in challenging low Earth orbit environments.

This role offers end-to-end ownership of the spacecraft power system, from concept through to launch and on-orbit operations, within a highly agile engineering team.

Key Responsibilities

• Define and maintain electrical power subsystem requirements, architecture, and ICDs

• Design and analyse solar arrays, batteries, and power conditioning/distribution systems

• Produce power budgets across all mission phases, including contingency cases

• Perform modelling, simulation, and worst-case analyses

• Select and qualify space-grade components considering radiation, thermal, and environmental constraints

• Support manufacturing, assembly, integration, and test (AIT) activities

• Develop and execute subsystem and system-level test plans (TVAC, vibration, functional)

• Lead and contribute to technical reviews (PDR, CDR, TRR)

• Interface with other spacecraft subsystems and support system-level trade studies

• Support launch preparation and early orbit operations, including on-orbit power monitoring and troubleshooting

Essential Requirements

• 3+ years' experience in spacecraft or satellite electrical power systems engineering

• At least one smallsat-class mission delivered to orbit

• Strong knowledge of solar arrays, batteries, and spacecraft power electronics

• Experience with power budget modelling, simulation tools, and hardware testing

• Familiarity with space-qualified components and radiation/thermal design considerations

• Hands-on experience with integration and testing in cleanroom environments

• Strong problem-solving ability and experience working in cross-functional engineering teams

• Clear communication skills for internal and supplier-facing collaboration

Package & Working Pattern

• Competitive salary with equity/options

• Comprehensive benefits package (including private healthcare)
