Electronics Engineer

Electronics Engineer, Next-Generation Space Communications - Location: Hybrid (Osney Mead, Oxford)
Industry: Space / Wireless Communications / Deep Tech Type: Full-time

About the Company

We are building the space-enabled connectivity networks of the future. Our mission is ambitious: to transform global communications infrastructure and help tackle some of humanity’s most critical challenges, from digital inequality to climate resilience.

As a fast-growing, innovation-driven start-up, we offer a highly collaborative, fast-paced environment where you’ll have the freedom to contribute, take ownership, and work on technologies that push the boundaries of what’s possible.

We’re looking for an Electronics Engineer to take ownership of designing, integrating, and testing complex electrical and thermal subsystems for our Optical Communications Terminal. This is a hands-on, multidisciplinary role where you'll collaborate with software, mechanical and optical teams to ensure our hardware is integration-ready and fully verified for Assembly, Integration, and Test (AIT).

If you thrive at the intersection of hardware and software, enjoy solving cross-domain engineering challenges, and want to build truly cutting-edge systems, this is the role for you.

What You’ll Work On (Subsystem Ownership)

• Lead end-to-end development of electrical, electronic, and thermal subsystems, including:
• Requirements definition and architecture design
• Trade studies and system-level decision-making

Electrical part/system design

• Basic mechanical mounts and enclosure design to support subsystem development
• Component selection, procurement, and supplier coordination
• Subsystem assembly, verification, and documentation
• Maintaining power budgets, ICDs, and all relevant system artefacts

Hardware–Software Integration

• Integrate and test systems at board and subsystem level
• Debug and implement communication protocols (CAN, SPI, UART, I2C)
• Collaborate closely with embedded software and firmware engineers

PCB & Harness Development

• Support PCB production, documentation, and design sign-off
• Develop, test, and maintain harnessing
• Coordinate with production partners and test teams

Testing & Ground Support

• Participate in formal engineering test campaigns
• Design and build electrical test equipment
• Ensure subsystem readiness throughout the full AIT flow

What You’ll Bring (Core Requirements)

• Strong background in electrical systems integration
• Hands-on experience with electrical hardware–software development
• PCB design, testing, and component library creation
• Experience managing engineering documentation and version control (e.g., GitHub)
• Skilled in electronic component selection and microcontroller bring-up
• Proficiency with electrical design tools:
• PCB tools (KiCad/Altium)
• Harness design tools (e.g., RapidHarness)

Nice-to-Have Skills

• Building and testing harnessing and supporting component procurement
• Experience designing brackets/mounts and using 3D printing for subsystem support
• Exposure to space, aerospace, or other high-reliability engineering environments (ECSS or similar)
• Experience in production processes from prototype to scaled hardware builds

Compensation & Benefits

Be part of a mission-driven team developing technology with global impact

• Hybrid working with flexibility tailored to you
• 25 days annual leave + bank holidays
• Equity options in a rapidly growing start-up
• Professional development budget and learning resources
• Supportive, collaborative culture with genuine ownership opportunities
• Weekly team lunches + regular socials
• Access to wellbeing and learning app subscriptions

If you're excited about shaping the future of space-enabled communications and want to work on complex, meaningful engineering challenges, this is your chance to make your mark.
