Mid Embedded Engineer

Onsite 5 days a week – Chiswick, London.

We’re hiring a Mid Embedded Engineer to help develop, test, debug, and integrate the electronics and firmware systems at the heart of the Holo Drive platform and help bring our ambitious first product to market.

At Holo Mem, 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 Holo Mem 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 Holo Drive 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  have ambitious plans, and we are now scaling up our West London based team to enable them. Join us.

You will work hands‑on across embedded software, electronics, test rigs, and prototype systems in a fast‑moving R&D environment. You will develop and maintain embedded systems and tooling that enable reliable experimentation, rapid iteration, and repeatable system performance.

Working at the interface of electronics, firmware, optics, and software, you will lead bring‑up, debugging, and preventative maintenance for defined rigs, boards, and prototype subsystems. You will also contribute to Holo Drive product integration by helping translate experimental systems into more robust, scalable, and maintainable engineering solutions.

This role requires practical embedded engineering judgement, strong debugging discipline, and the ability to make progress when requirements are still evolving.

This role is suited to a mid‑level embedded engineer who can demonstrate the ability to:

• Develop, test, and debug embedded software for prototype and product‑adjacent systems
• Own defined embedded work streams from implementation through bring‑up, validation, and documentation
• Support the design, integration, and maintenance of precision electronic and electromechanical systems
• Work with microcontrollers, sensors, motors, encoders, drivers, and communication interfaces
• Improve the repeatability, reliability, and maintainability of experimental platforms
• Create practical tools, scripts, or test routines that improve engineering speed and system visibility
• Diagnose issues across firmware, electronics, mechanical interfaces, and lab setup
• Collaborate with electronics, optics, software, and product teams to integrate embedded systems into wider prototypes
• Work hands‑on in our Chiswick office and R&D lab

You are a practical, curious embedded engineer who enjoys working at the boundary between electronics and software. You are comfortable debugging real hardware, writing reliable firmware, and taking responsibility for defined technical deliverables.

You are not expected to have solved every problem before, but you should be able to reason clearly, test systematically, communicate uncertainty, and make sound engineering decisions without needing constant direction.

You are likely to enjoy this role if you like building things that have to work in the real world: motors that move repeatably, sensors that produce trustworthy data, rigs that stay reliable, firmware that fails predictably, and test tools that help the wider team move faster.
