Your role
This is a full-time hybrid role for a Field Service Engineer & Technical Operations Owner based in the Greater Barcelona Metropolitan Area. While some work can be performed remotely, the role involves on-site tasks, requiring proximity to the region. You'll be responsible for taking technical ownership from lab to real-world environments, owning the full technical lifecycle of our deployed instrumentation:
It’s a hands-on individual contributor position (no direct reports). If you enjoy solving hard problems on-site, improving systems end-to-end, and working in a small team where execution matters—this is for you.
