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:

• Deployment, validation, and support management across customer/partner sites
• Debug & develop hardware and firmware for new instrumentation
• Prepare and maintain the latest technological equipment in industrial settings
• Formulate test plans and validation procedures to ensure device and system performance
• Provide direct technical insight to key engineering changes that improve user experience, reliability, and maintainability
• Contribute to the continued development of microsensing instruments and algorithms for decision support and control
• Act as a point of contact for clients, ensuring exceptional customer service and operational efficiency.

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.

What you’ll bring

• MSc or PhD in IT/Electrical Engineering (or related field)
• Experience in Field Service operations, including the ability to perform installation, maintenance, and on-site repairs
• Strong Troubleshooting and Technical Support skills to identify and resolve technical issues efficiently
• Hands-on embedded systems experience (hardware + firmware/software) and comfort debugging in the field

What you’ll get

• Real technical ownership and direct product impact
• Exposure to real-world industrial constraints (and the authority to fix them properly)
• A chance to shape both the instrumentation and the intelligence layer behind it
• A small-team environment: high responsibility, fast feedback loops, low bureaucracy
• Flexible and hybrid/remote working hours (and hybrid/remote when compatible), a personal learning budget (courses/conferences), and modern equipment/tooling—so you can keep growing while doing high-impact work.
