Lead Mechanical Engineer We’re working with an ambitious engineering team developing next-generation hardware designed to operate in some of the harshest environments on Earth. This is a lead, hands-on role in a fast-moving, startup-style environment where engineers take full ownership from concept through to deployment. You’ll play a key role in shaping the mechanical design of critical systems, leading development from early-stage concepts through to real-world testing and operational use. If you enjoy building, testing, iterating, and solving complex engineering challenges within a small, high-performing team, this is a role where you’ll thrive. What you’ll be doing Leading the design and development of ruggedised, cold-hardened mechanical systems Taking full ownership of hardware from concept through to production and field deployment Developing systems capable of operating under extreme thermal and mechanical stress Driving materials selection, sealing strategies, and structural design for harsh environments Building and testing prototypes, including validation in environmental and cold chamber conditions Working closely with electrical, RF, software, and systems engineers in a highly collaborative team What we’re looking for 7 years’ experience developing real-world hardware Degree in Mechanical or Aerospace Engineering Experience working within Aerospace or Defence industries (essential) Strong 3D CAD skills (Siemens NX, SolidWorks, or similar) Proven experience taking products from concept to production, including DFMA A hands-on engineer who enjoys prototyping, testing, and solving real-world engineering problems Apply today ro contact Gemma for more information
