At NewOrbit Space, our mission is to engineer the lowest orbiting satellites on Earth to rapidly advance global connectivity and insight. We are currently building satellites that can operate at an altitude of just 200 km - one-third that of conventional satellites. Thanks to our propulsion system AURA, we can compensate for the atmospheric drag at ultra-low altitudes. 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. Your expertise in smallsat-class spacecraft will enable you to optimise performance under tight mass, volume, and schedule constraints in a fast-paced, agile environment.
Job Responsibility:
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
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
What we offer:
Equity and Competitive Salary
Comprehensive Benefits Package – Including private health insurance with dental and optical coverage, annual healthcare check-ups etc
Hybrid Work - A hybrid setup with one dedicated remote day per week
We provide a relocation package and sponsor your visa if you’re joining us from abroad
