Full-time position.
Onsite 5 days a week - Chiswick, London.
Design the Future of Sustainable Storage
At HoloMem, we're building the next generation of long-term data storage — radically efficient, ultra-durable, and environmentally sustainable. Our pioneering holographic storage technology encodes data as light within advanced materials, creating a resilient alternative to today's short-lived, energy-intensive cloud infrastructure.
Having partaken in both the Intel Ignite and Deeptech Labs accelerators in 2024, awarded two Innovate UK Smart Grants, we've recently closed our Seed+ raise and are accelerating development. To help bring our ambitious product to life, we're hiring a Senior Mechanical / Mechatronics Engineer to lead the design and integration of precision electromechanical systems at the heart of our platform.
What You'll Be Doing
This is not about integrating off-the-shelf components or following conventional design cycles. At HoloMem, you'll own the design and build bespoke internal mechanical systems — think precision motion, tape transport, and microcontroller integration — crafted specifically for our cutting-edge data storage architecture. You'll move fluidly between CAD and the lab, collaborating closely with physicists, materials scientists, and engineers to prototype and iterate at speed.
The Role
* Push the capabilities of holographic data storage technologies by creating innovative solutions to challenging problems
* Design and develop precision mechanical and electromechanical subsystem
* Drive innovation by challenging conventional thinking and developing creative, impactful solutions that push boundaries
* Integrate motion systems with microcontrollers, sensors, and actuators
* Be a technical leader within a within a cross-functional group of mechanical, optical and software engineers, providing critical feedback and suggestions for continuous improvement
* Diagnose and debug electromechanical and control system challenges
* Work hands-on in our Chiswick lab — designing, building, testing, and refining
Who You Are
We're looking for a pragmatic, creative engineer who thrives at the interface of mechanics and electronics. You bring a strong mechanical foundation, with the range and curiosity to work across disciplines and solve real-world, physical problems.
Expected
* 5+ years' experience in mechanical or mechatronics engineering, ideally in a high-tech R&D or product environment
* A degree in Mechanical Engineering, Mechatronics, or a related discipline
* A portfolio of projects — robotics, automation, mechanical, or motion systems
* Strong 3D CAD skills and experience producing drawings and building assemblies
* Hands-on prototyping experience (machining, 3D printing, assembly, soldering)
* Experience designing for motion — motors, actuators, bearings, encoders, etc.
* Solid grasp of mechanical fundamentals — kinematics, materials, tolerancing, failure modes
* Excellent communication and interpersonal skills to collaborate effectively within cross-functional teams.
* Demonstrated ability to work in a fast-paced, dynamic startup environment
Desirable Skills
* Practical experience with GD&T and mechanical metrology
* Familiarity with embedded microcontrollers (Arduino, STM32, Raspberry Pi)
* Firmware development in C/C++
* Scripting in Python for test automation or data analysis
* A background in optics, photonics, or precision instrumentation
What You'll Get
* Competitive salary
* 25 days annual leave
* Employer pension contributions
* Cycle-to-work scheme
* A collaborative, knowledgeable team working on deeply technical, world-positive problems
