About K3Metrology
K3Metrology is a deep-tech spin-out from the UK’s National Physical Laboratory (NPL), commercialising Metralis® — a next-generation, laser-based, large-volume coordinate measurement system developed over 15 years at the UK’s National Measurement Institute.
Metralis delivers real-time, multi-object tracking with sub-0.1 mm precision, SI traceability, and built-in uncertainty, enabling fully digital and automated manufacturing. The technology is backed by major industrial partners including aerospace primes and advanced clean energy companies.
The Junior Instrument Engineer will play an important role in supporting the development of the core technology and contributing to the engineering culture of the company.
Role overview
We’re looking for an early-career Instrument Engineer to join our team and help turn our technology into a commercial product.
This is a hands-on engineering role where you’ll contribute across hardware, testing, and system development. You’ll work closely with experienced engineers and gain a broad understanding of how a complex measurement system is designed, built, and tested.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
