Mechanical Engineer

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.

• 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.

• 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 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

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.

• 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)
• 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
• Practical experience with GD&T and mechanical metrology
• Familiarity with embedded microcontrollers (Arduino, STM32, Raspberry Pi)
• Scripting in Python for test automation or data analysis
• A background in optics, photonics, or precision instrumentation

• 25 days annual leave
• Employer pension contributions
• A collaborative, knowledgeable team working on deeply technical, world-positive problems
