Senior Electronics Engineer

Archangel Lightworks is a laser communications company building wireless technology. Founded in 2017, we believe that laser communications to and from satellites is a key component of next-generation infrastructure. Our core product, the TERRA-M, is a deployable optical ground station with proven capability for space - ground data transfer.

Our team develops and operates products that advance the security and resilience of critical national infrastructure. We value compassion, resilience, curiosity, ownership and integrity. Our start-up is a fast-paced and supportive environment, where you can contribute to novel technology with meaningful applications like reducing the Digital Divide.

Archangel Lightworks recently closed over £10 million of investment in an oversubscribed Series A funding round. Our company is also supported by the UK Space Agency, the UK’s Department of Science and Technology (DSIT) and the UK Ministry of Defence.

We are seeking a Senior Electronics Engineer to lead the design, integration, and testing of complex subsystems within our Optical Communications Terminal. This is a hands-on, highly collaborative role. You’ll work closely with our software, mechanical, and optical teams to ensure that all systems are integration-ready and fully verified for Assembly, Integration, and Test (AIT).

Your responsibilities will include:

• Providing strategic leadership of the electronics function to meet organisational objectives
• Subsystem Ownership, leading the end-to-end development of electrical and electronic subsystems:
  • Requirements definition
  • Architectural design and trade studies
  • Design of electrical parts/systems
  • Component selection, procurement, and supplier coordination
  • Subsystem assembly and verification
  • Maintain power budgets, interface control documents, and system artifacts
• Hardware-Software Integration:
  • Integration at board and subsystem level
  • Implement and debug communication protocols (e.g. CAN, SPI, UART, I2C)
  • Coordinate with embedded software and firmware teams
• PCB and Harness Development:
  • Support PCB production, documentation, and sign-offs
  • Design, test, and maintain system harnessing
  • Collaborate with production partners and testing teams
  • Delegate work and provide reviews and mentorship to colleagues
• Testing & Ground Support:
  • Participate in formal test campaigns
  • Design electrical test equipment
  • Ensure subsystem readiness for full AIT flow.

• 5+ years in electronics development with end-to-end ownership of complex electronic subsystems; proven track record delivering to schedule, cost, and quality
• Strong background in electronics design theory, University degree or similar
• Demonstrated experience with electrical hardware-software development:
  • Schematic design
  • PCB layout and testing PCB Component library part creation and maintenance
  • Manage engineering documentation and version control (such as Github)
  • Electronic component selection
  • EMC compliance
  • Microcontroller programming and debugging for board bringup
• Good knowledge of Electrical design tools:
  • PCB tools (e.g. Kicad/Altium)
  • Simulation (e.g Spice)
  • Harness design tools (e.g. Rapid Harness)
• Experience of mentoring junior engineers.

• High speed electronics design for communications interfaces (Gbps)
• Design for complex System-on-Chip components (e.g. Xilinx)
• Experience building & testing harnessing; selecting and procuring electrical components
• Exposure to space, aerospace, or high-reliability environments (ECSS or similar)
• Experience designing or supporting production processes from prototype to scaled hardware builds
• Experience in Tooling and process leadership: requirements management (e.g., DOORS/Jama/SysML), CI for hardware/firmware, configuration control, and traceability…
