As a Senior Mechanical Engineer, you will own hardware subsystems end‑to‑end, from early concept through to production. Working in a multidisciplinary team of ex‑Dyson engineers, you’ll solve complex challenges in fluidics, optics, and precision motion. This is a high‑impact, on‑site role at the intersection of hardware and life‑saving biology.

• You’ll build machines that directly accelerate the development of life‑saving cures, with cells grown on Mytos hardware heading into Parkinson’s clinical trials next year.
• Work at the Imperial College Innovation Hub within a world‑class team of ex‑Dyson engineers and Nature‑published scientists backed by Y Combinator and $19M in funding.
• Experience true technical autonomy by owning complex electro‑mechanical subsystems from initial concept through to manufacturing and field deployment for multibillion‑dollar biotech clients.

• Lead the end‑to‑end design and development of complex hardware subsystems, integrating precision optics, fluidics, and motion control into robust, indestructible devices.
• Iterate on existing proof‑of‑concept features to improve reliability and robustness, ensuring machines perform with high precision in tandem with electronics and firmware.
• Refine manufacturing and quality processes, utilizing techniques like injection molding, CNC machining, and sheet metal fabrication to move from prototype to production.

• Has a proven track record of shipping complex electro‑mechanical products to market, ideally within lab automation, medical devices, or the biotech industry.
• Demonstrates deep technical expertise in mechanical design for reliability and manufacture, including experience with fluidics, sealing, and precision liquid paths.
• Thrives in a fast‑paced, multidisciplinary environment and possesses the independence to make critical design calls while collaborating closely with software and firmware teams.
