About Invisix

Semiconductor manufacturers can't build what they can't measure. Invisix Measuring Systems is a fast-growing scale-up in the high-tech industry, developing next-generation metrology solutions for the semiconductor sector. We work at the intersection of optics, software, and data.

We're a small team, but the depth of knowledge inside Invisix is anything but small. Our culture is professional and fast-paced, with short communication lines and a strong sense of shared purpose. Everyone here is committed, and everyone knows their work directly contributes to something bigger.

The Role

We're looking for an Experimental Physicist to build and improve the next-generation soft X-ray (SXR) source at the core of our metrology equipment.

You'll work in our lab with experienced colleagues who know this technology inside out. You take setups from first assembly to stable operation, find out what limits their performance, and turn what you learn into specifications for our metrology equipment.

Key Responsibilities

Build, align and commission the optical and vacuum systems of our test bench, and bring them into stable operation

Set up and run diagnostics to characterize the SXR light and the optical systems that generate it

Measure and optimize the performance of the SXR source, and turn what you learn into specifications for our metrology equipment

Solve hardware issues, find practical solutions and test new ideas quickly

Control experiments and analyze the data, working with detectors, motion control and data acquisition

Work with our experienced physicists and engineers, and take on adjacent responsibilities as the team grows, such as test bench design or contacts with suppliers

Is this you?

PhD in physics, optics, photonics, electrical engineering or a related field, or an MSc in one of these fields with 3 to 5 years of relevant experience in a high-tech environment

A strong grasp of the physics, so an unexpected result becomes a clue rather than a roadblock, and a safe, structured way of working in the lab, independently and as part of a team

Hands-on experience with high-power or ultrafast laser systems and optical setups, in academia or industry

Experience with optical measurement and diagnostics, such as spectroscopy, imaging, beam profiling, pulse characterization or power measurement

Experience with vacuum systems and lab instrumentation, such as detectors, motion control and data acquisition

Programming skills for data analysis or instrument control, for example in Python, MATLAB or LabVIEW

Good spoken and written English

Active use of AI tooling in your daily work (data analysis, instrument control scripts, documentation) to boost efficiency

Nice to have

Experience with SXR or XUV optics and detection

Experience in laser or optical engineering

Experience with opto-mechanical or in-vacuum design

Experience with EUV or SXR metrology for semiconductors

What We Offer

A hands-on role in our lab where your work directly shapes the product, with experienced physicists and engineers to learn from every day

Competitive salary and benefits, including an Employee Share Ownership Plan

A learning and development budget to support your growth

Flexible working arrangements, and room to grow into adjacent responsibilities as the team scales
