Senior Manufacturing Technician
Optical & Semiconductor Systems

£38,000–£45,000 depending on experience + EMI Share Options + Private Healthcare

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

Generous EMI share option scheme
Private healthcare
Death in service benefit

About Us

Based in Abingdon, Oxfordshire, Infinitesima is a rapidly growing deep-tech company developing next-generation metrology solutions for the semiconductor industry.

Backed by leading global investors, including Applied Ventures, we're combining world-class engineering, physics and software expertise to solve some of the industry's most complex measurement challenges.

What You'll Be Doing

Manufacture and test complex sub-assemblies involving optical, cabling, and electro-mechanical technologies, ensuring compliance with quality and performance standards.
Identify, investigate, and report manufacturing issues, leading first-level containment and working closely with engineering and support teams to implement effective resolutions.
Lead process discipline and shift stability, driving continuous improvement initiatives that enhance manufacturing quality, reliability, and efficiency.
Mentor and support colleagues, ensure BoM kit readiness, and maintain high standards of housekeeping and health and safety.
Support the achievement of production and delivery schedules through high-quality, right-first-time assembly and test.
Coordinate the integration of critical modules into advanced semiconductor metrology systems, ensuring compliance with quality, performance, and manufacturing standards.

What We're Looking For

You'll come from within semiconductor equipment, photonics, scientific instrumentation, aerospace, medical devices or another advanced technology manufacturing environment.

Senior Manufacturing Technician experience, or a minimum of five years' experience in a Manufacturing Technician role.
Experience with setting up optical systems, laser building, fibre optics, electronics, and electro-mechanical assembly and test.
Proven experience in the build and test of complex, high-value technology products.
Experience working in cleanroom manufacturing environments.
Strong troubleshooting, fault-finding, and root cause analysis skills.
Experience supporting products from development through to production.
Good understanding of manufacturing quality systems and best practices.
Ability to read and interpret engineering drawings and technical documentation.
Experience building and testing precision assemblies with exceptional attention to detail.

Nice to Have

Semiconductor equipment manufacturing experience
AFM, metrology, photonics or scientific instrumentation experience
IPC wiring and soldering certification
Manufacturing engineering or process development exposure
Knowledge of Lean, Six Sigma, or other continuous improvement methodologies.
Experience supporting low-volume, high-complexity products

Qualifications

HND, degree, apprenticeship or equivalent practical experience in engineering, manufacturing, photonics, electronics, electro-mechanical assembly or a related discipline.

Our strength lies in the varied perspectives that come from different cultures, experiences, and identities. We believe that true innovation is fuelled by collaboration, locally and globally. We strive to foster an environment where everyone can contribute meaningfully and thrive. If you require adjustments to take part in the recruitment process, please let us know, we'll do our best to support you.

A note on how we run interviews:
