£33,000 to £40,000 depending on experience

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 a skilled Manufacturing Technician to build, integrate and test the high-precision optical, electro-mechanical and photonic systems that sit at the heart of our technology.

This is an opportunity to join a fast-growing technology company where your work has a direct impact on the performance of complex scientific instruments used by global semiconductor manufacturers.

If you enjoy solving problems, working with precision hardware and taking ownership of build quality from assembly through to test, we'd love to hear from you.

What you'll get

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, document, and escalate manufacturing issues—including defects, downtime, and abnormalities—using factual information, while collaborating with cross-functional support teams to drive timely and effective resolution.
Working as a manufacturing team in maintaining and continuously improving manufacturing processes to enhance product quality and operational efficiency.
Ensuring assemblies are delivered to quality, cost and schedule requirements
Maintain high standards of housekeeping and cleanliness across production and cleanroom environments.
Liaise with Stock Operatives to ensure assembly kits are complete & accurate.
Contributing to a safe, organised and high-performing manufacturing environment

What we're looking for

You'll ideally come from semiconductor equipment, photonics, scientific instrumentation, aerospace, medical devices or another high-tech manufacturing environment.

We'd particularly like to hear from people with experience of:

Building and testing complex, high-value technology products
Electro-mechanical assembly and system integration
Root cause analysis and structured problem solving
Manufacturing practice, quality standards and root-cause basics
Reading and following technical documentation and build procedures
Working with precision mechanical and electronic components
Strong attention to detail and pride in workmanship

Nice to have

Semiconductor equipment or semiconductor manufacturing experience
Cleanroom working experience
Wiring and soldering to IPC standards
Experience working with complex photonics or metrology equipment, such as optical systems, lasers, fibre optics, and precision instrumentation.
Manufacturing engineering or process improvement exposure

Qualifications

A HND, degree, apprenticeship or equivalent hands-on experience in engineering, manufacturing, electronics, photonics 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.
