What you need

  • Degree, apprenticeship-based qualification, or equivalent practical experience in mechanical engineering, physics, engineering science, hardware design or a related discipline.
  • Around 1–2 years of relevant post-degree or post-PhD experience, or equivalent hands-on experience in a demanding engineering environment.
  • Experience contributing to the design, build and validation of precision hardware or experimental systems.
  • Good mechanical design skills, including CAD and production of engineering drawings.
  • Experience with mechanical and/or thermal modelling, analysis or simulation.
  • Experience working with precision assemblies, fragile components or tightly constrained mechanical systems.

Nice to have

  • Experience in high-performance optical, photonic, cryogenic, vacuum or scientific instrumentation systems.
  • Experience from demanding experimental hardware environments such as large-scale physics experiments, advanced photonics R&D, precision metrology, aerospace, semiconductor tools, or high-specification laser systems.
  • Experience with optomechanical or fibre-based hardware packaging.
  • Experience developing mechanically and thermally stable hardware for precision systems.
  • Experience with environmental control, thermal stabilisation or feedback-controlled hardware.

What you get

  • Base salary range of £50,000 — £56,000 GBP.
  • Eligible for equity and benefits.

Worth weighing

  • No specific information on the company culture or work-life balance is provided.
