The Electronics team is where the magic happens - from power systems and flight computers to comms boards and payload interfaces, they make sure every mission succeeds. It’s creative, hands-on, and mission-critical work — solving tricky problems, testing every circuit, and making sure our satellites are ready to thrive in the toughest environment of all: Space.

What You'll Be Doing

As an Electronics Engineer you’ll be a key contributor to the design, development, and maintenance of our satellite Electronic Power System (EPS). You’ll work closely with the Senior Engineer and cross-functional teams to ensure the power system is robust, reliable and high-performing. This is hands-on role covering the full product lifecycle, from initial design concepts to streamlining production.

As a member of the Electronics Team, you will:

• Conduct design and validation of power electronics circuits across the EPS architecture from solar panel design to BMS to distribution modules
• Driving and implementing DFM practices and design principles to streamline assembly and maximise yield
• Designing and executing comprehensive test plans throughout the product lifecycle from prototype through to verification testing
• Maintaining documentation, changelogs and future development planning for mature designs
• Contributing to innovative designs for next-generation satellite power systems
• PCB design and schematic capture
• Working in close cross-disciplinary with the other Engineering teams to ensure compatibility of the EPS with mission requirements

What You’ll Bring

• Core competency in power electronics design
• Demonstrated expertise in electromagnetic compatibility (EMC) design and noise reduction techniques
• Strong ability in analogue and digital circuit design from schematic capture to adept PCB layout
• Awareness of design-for-space principles
• Proven hands-on experience in testing, debugging and troubleshooting electronics at component & system level
• Confidence in understanding of embedded systems and MCUs used, programming ability would be of significant advantage
• Quality orientated approach to design and development
• Familiarity with DFM principles would be of great benefit
• A strong communicator with excellent verbal and written skills for discussing technical issues and solutions.
• Eager to learn and adapt quickly in a fast-paced engineering environment.

This role will be based in Harwell, UK. To apply, you must have the legal right to work in this location.
