Systems Technician

We at Cerca Magnetics Limited (Cerca) all have a shared goal: to make a real difference to people's lives through technological advances. If you want to do the same, joining our passionate team of technical, engineering and business experts might be the right career move for you.

Cerca was founded in 2020 and works in partnership with The University of Nottingham and Magnetic Shields Limited. The team have commercialised the world's most advanced functional brain scanner - a lightweight wearable device that uses Optically Pumped Magnetometers (OPMs) to measure the magnetic fields within the brain. Unlike other scanners such as MRI, our system can be worn by both adults and children as the participant can move whilst being scanned. The information provided could contribute towards medical advances in treating epilepsy and other neurological conditions such as mTBI and dementia. We are currently working towards gaining medical approvals for use in epilepsy diagnosis and treatment.

Following initial sales in the research market, Cerca's vision is to offer the system to healthcare providers around the world and revolutionise functional brain imaging; to make a real difference to those that suffer from debilitating neurological problems. We share a dream of contributing towards the treatment of a young child who instead of facing a life suffering with daily epileptic seizures, could live their life free from the condition.

As Systems Technician at Cerca, you will be instrumental in preparing, installing, calibrating, and servicing our cutting edge wearable OPM MEG scanners. This hands on role ensures products are rigorously tested before shipping, expertly set up at customer sites, and supported throughout their operational lifecycle. You will also contribute to the development and scientific validation of new offerings, bolster technical infrastructure, and drive software migration initiatives-all supporting Cerca's mission to revolutionise functional brain imaging.

The Systems Technician will enable the successful deployment and evolution of wearable OPM-MEG systems, empowering researchers globally. You will ensure our systems are not only designed and built with precision but also supported through their entire lifecycle.
