Join Our Client's Innovative Space Team as a Satellite Electrical Power Systems Engineer

About Our Client

Our Client operates at the forefront of spacecraft technology within the aerospace sector. Renowned for pioneering developments in low Earth orbit satellite platforms and advanced propulsion systems, they are shaping the future of global connectivity and space exploration. Recognised for their collaborative culture, innovative approach, and commitment to excellence, they attract talented professionals eager to make a significant impact in space technology. Their supportive environment fosters growth, offers comprehensive benefits, and provides unique opportunities to work on cutting-edge projects that push the boundaries of possibility.

Role Overview

In response to expanding project needs and strategic growth, our Client is seeking a highly skilled Satellite Electrical Power Systems Engineer. This key position offers an exciting opportunity to lead the end-to-end design and development of satellite power subsystems. As a vital contributor to the mission success, you will influence the entire lifecycle of smallsat-class spacecraft, ensuring reliable power integration in demanding ultra-low Earth orbit environments. Your expertise will help expand the capabilities of revolutionary satellite architectures, directly impacting global communications and insight.

Key Responsibilities

• Develop and maintain detailed requirements, architecture, and interface documents for the power subsystem
• Design and evaluate solar array, battery, and power distribution systems aligned with mission parameters
• Conduct comprehensive power budgeting and sizing analyses for all mission phases, including contingency planning
• Model, simulate, and perform worst-case scenario analyses to validate system resilience
• Select and qualify components suitable for space environments, considering radiation, atomic oxygen impacts, and thermal factors
• Support manufacturing, assembly, integration, and testing activities for the power subsystem
• Lead subsystem and system-level testing, including functional, thermal vacuum, and vibration assessments
• Facilitate design reviews (Preliminary Design Review, Critical Design Review, Test Readiness Review) and ensure system readiness
• Collaborate with multidisciplinary teams to optimise system efficiencies and perform trade-off studies
• Participate in launch support and monitor on-orbit power performance, troubleshooting as needed
• Minimum of 3 years' experience in spacecraft or satellite power subsystem engineering, with at least one smallsat mission successfully delivered to orbit
• Robust knowledge of spacecraft electrical systems, including solar array and battery technologies
• Proven experience with power budgeting, system modelling, and simulation tools
• Familiarity with space-qualified components and thermal/ radiation design considerations
• Practical experience in integration and testing within cleanroom environments
• Strong problem-solving abilities, with the capacity to work effectively within agile, cross-disciplinary teams
• Excellent communication skills to liaise with suppliers, subsystem teams, and mission stakeholders
• Hands-on experience with power electronics design and fault analysis
• Knowledge of advanced battery chemistry and thermal management solutions
• Understanding of satellite system trade-offs and mission optimisation strategies
• Experience with space authorities' standards and certification processes

Why Apply?

This is your chance to become part of a pioneering space enterprise that is transforming the satellite industry. Your work will directly influence the development of low Earth orbit satellites that redefine connectivity and data insight. Our Client values ownership, innovation, and collaborative spirit - rewarding your contributions with meaningful roles, comprehensive benefits, and unique career growth opportunities. Join a talented team pushing the boundaries of space technology and making impactful contributions that reach beyond our planet.
