Electronics Engineer in London

Full-time position. Onsite 5 days a week – Chiswick, London. We’re hiring an Electronics Engineer to develop, bring up, validate, and support the manufacture of PCB assemblies for the HoloDrive system.

About HoloMem - At HoloMem, we’re building the next generation of mass data storage hardware; highly efficient, long life, and ultra durable. Our pioneering and patented holographic technology encodes data as light within advanced polymers, enabling a resilient and future fit alternative to today’s short lived and energy intensive data storage infrastructure. Over the past 24 months HoloMem has graduated from both the Intel Ignite and Deeptech Labs accelerators, been awarded two Innovate UK Smart Grants, closed a seed+ funding round, and most recently deployed a working HoloDrive prototype to a live data centre to prove the robustness of our system. Off the back of our breakthrough partnership with BDT, the world’s largest tape library manufacturer, we now begin the transition from prototype to product, maturing our validated system into a mass-produced technology platform that enables state of the art data storage performance at scale. We have ambitious plans, and we are now scaling up our West London based team to enable them. Join us.

What You’ll Be Doing - You will work on PCB development for HoloDrive subsystems, supporting electronics from prototype builds through manufacturing readiness. The role will cover schematic capture, PCB layout ownership or coordination with layout support, component selection, board bring-up, debugging, validation, and release documentation. You will help improve PCB reliability, testability, and manufacturability as the system matures. This includes designing with DFM and DFT in mind, preparing fabrication and assembly packs, supporting component sourcing and substitutions, and helping resolve PCB assembly issues.

The Specifics About the Role - This role is suited to an electronics engineer with industry experience developing real PCB hardware, bringing boards up in the lab, and supporting the practical transition from prototype electronics into manufacturable assemblies. You should be able to:

• Create and update PCB schematics for defined HoloDrive subsystems
• Own PCB layout activity directly or work effectively with external or internal layout support
• Select components with consideration for performance, availability, cost, lifecycle, and manufacturability
• Bring up and debug new PCB assemblies using lab equipment and structured test methods
• Work across analog, digital, sensor interface, motor driver, power electronics, and high-speed digital circuits
• Prepare fabrication and assembly documentation for prototype and manufacturing builds
• Support EMC, reliability, and validation testing for electronics assemblies
• Investigate PCB assembly issues and support practical fixes with suppliers or manufacturing partners

Who You Are - You are a practical electronics engineer who enjoys taking PCB designs from schematic through layout, build, bring-up, debug, and validation. You are comfortable working at the bench, reading signals, checking assumptions, and finding the difference between a design issue, an assembly issue, a component issue, and a test setup issue. You care about whether hardware can be built repeatedly, tested properly, and supported beyond the first prototype. You think about component availability, layout constraints, test points, assembly quality, and documentation before they become late-stage problems.

Required Experience - Degree-level education in electronic engineering, electrical engineering, mechatronics, or a closely related discipline. Around 2–5 years of relevant industry experience developing PCB-based electronics. Experience with PCB schematic capture and board-level design. Experience with high-speed PCB layout considerations, including controlled impedance, length matching, signal integrity, and tight-timing interfaces such as DDR. Experience bringing up, testing, and debugging PCB assemblies in the lab. Experience with analog and digital electronics. Some industry experience with power electronics. Experience using Altium, KiCad, EasyEDA, or similar PCB design tools. Experience with sensor interfaces, motor driver circuits, or control electronics. Exposure to high-speed digital design considerations. Experience preparing fabrication and assembly packs for PCB manufacture.

Desirable Skills - Experience resolving PCB assembly issues with suppliers, manufacturers, or assembly partners. Experience supporting component sourcing, substitutions, lifecycle checks, or availability-driven redesigns. Experience supporting EMC, reliability, environmental, or validation testing. Experience working with motor control electronics, motor drivers, encoders, or sensor feedback systems. Experience with mixed-signal PCB design. Experience with test fixture design, production test, or end-of-line test considerations. Experience working with external PCB layout engineers, PCB fabricators, or contract manufacturers. Familiarity with revision control, engineering change control, and hardware release documentation.

Benefits At HoloMem - Competitive salary, 25 days annual leave, employer pension contributions, cycle-to-work scheme, a collaborative, knowledgeable team working on deeply technical, world-positive problems.
