Senior Manufacturing Technician – Optical & Semiconductor Systems
£38,000–£45,000 depending on experience + EMI Share Options + Private Healthcare + Pension
Help build the technology enabling the next generation of semiconductors.
At Infinitesima, we're developing advanced metrology systems that allow the world's leading semiconductor companies to measure and understand materials at the nanoscale.
We're looking for an experienced Senior Manufacturing Technician to build, integrate and test the precision optical, electro-mechanical and photonic assemblies that form the heart of our breakthrough technology.
This is not a high-volume production role.
You'll work on complex, high-value systems, collaborating closely with engineers and scientists to solve manufacturing challenges, improve processes and ensure our products perform to the highest standards.
If you enjoy combining hands-on build expertise with problem-solving and continuous improvement, we'd love to hear from you.
Reward & Benefits
- £40,000–£45,000 depending on experience
- Generous EMI share option scheme
- 25 days holiday plus bank holidays
