Graduate Engineer/ 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. At HoloMem, we’re building the next generation of mass data storage hardware; 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.

You will work on PCB development for HoloDrive subsystems, supporting electronics from prototype builds through manufacturing readiness. 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
• Helping resolve PCB assembly issues

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.

Key responsibilities include:

• Selecting components with consideration for performance, availability, cost, lifecycle, and manufacturability
• Bringing up and debugging new PCB assemblies using lab equipment and structured test methods
• Working across analog, digital, sensor interface, motor driver, power electronics, and high-speed digital circuits
• Preparing fabrication and assembly documentation for prototype and manufacturing builds
• Supporting EMC, reliability, and validation testing for electronics assemblies
• Investigating PCB assembly issues and supporting practical fixes with suppliers or manufacturing partners

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 think about component availability, layout constraints, test points, assembly quality, and documentation before they become late-stage problems.

Qualifications:

• 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 bringing up, testing, and debugging PCB assemblies in the lab
• Experience with analog and digital electronics
• Some industry experience with power electronics
• 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
• Experience resolving PCB assembly issues with suppliers, manufacturers, or assembly partners
• Experience supporting EMC, reliability, environmental, or validation testing
• Experience working with motor control electronics, motor drivers, encoders, or sensor feedback systems
• Experience working with external PCB layout engineers, PCB fabricators, or contract manufacturers
• Familiarity with revision control, engineering change control, and hardware release documentation

Benefits include:

• Competitive salary
• ~25 days annual leave
• ~ Employer pension contributions
• ~ Cycle-to-work scheme
• We value diversity and are committed to building an inclusive environment for all.
