About the Role

Mesa Quantum UK is seeking a Senior Mechanical Engineer to lead the mechanical, thermal, and packaging design of chip-scale atomic devices, including atomic clocks, magnetometers, and gyroscopes. This role involves owning mechanical design from prototype to manufacturable product, collaborating with UK and US engineering teams, and establishing the engineering foundation for Mesa Quantum UK.

Responsibilities

  • Build thermal models and correlate them to measured data.
  • Own the mechanical and thermal design of chip-scale atomic clocks, magnetometers, and gyroscopes from concept through production release.
  • Design magnetic shielding and field control for each device type.
  • Design hermetic and vacuum packages, verified with leak testing and outgassing-controlled materials.
  • Run structural, modal, vibration, and shock analysis, and design for environmental testing.
  • Own tolerance stacks and optical alignment with production-quality drawings.
  • Design and build test fixtures, assembly tooling, and environmental test setups.
  • Drive design for manufacture and assembly with suppliers and support transfer to volume production.
  • Share a common mechanical design approach across product lines, working with physics, photonics, electronics, and manufacturing teams.
  • Establish mechanical design standards, documentation, and configuration control for the UK team.
  • Work with partners in the UK quantum ecosystem on joint development and testing.
  • Design thermal isolation for heated vapor cells and lasers.

Requirements

  • At least 6 years of experience designing precision mechanical hardware, with at least one design taken from prototype to production.
  • Expert 3D CAD skills (SolidWorks, Creo, or similar) and production-quality drawings with GD&T.
  • Thermal and structural finite element analysis (ANSYS, COMSOL, or similar), correlated to test data.
  • Experience designing small hardware where millimeters and milliwatts matter.
  • Experience with vacuum or hermetic packaging: sealing methods, leak testing, outgassing control, and cleanliness.
  • Hands-on build and test skills: assemble prototypes and run thermal and vibration tests.
  • Clear technical documentation and ability to work directly with machine shops, package vendors, and contract manufacturers.
  • Experience with atomic clocks, magnetometers, gyroscopes, or other quantum sensors, magnetic shield design, MEMS or microelectronic packaging, laser or photonics packaging, or defense, aerospace, or space hardware and environmental qualification is valuable.
  • A degree in mechanical engineering, or a physics or engineering degree with equivalent mechanical design experience.
  • Eligible to work in the UK.
