Senior Mechanical Systems Engineer – Precision Metrology

Rotterdam, Zuid-Holland, Netherlands February 25, 2026

This role is centered on delivering high performance mechanical subsystems — from concept to detailed design, prototyping, integration, and validation. You will work hands-on with complex mechanisms such as precision stages, sensor modules, flexure-based architectures, dynamic structures, and ultra stable reference frames. Working in a multidisciplinary team, you’ll ensure that your designs meet demanding performance targets in stiffness, dynamics, thermal stability, accuracy, and reliability.

If you enjoy solving complex mechanical challenges and turning cutting edge concepts into working hardware, this role is for you.

Key Responsibilities

  • Design and deliver precision mechanical subsystems including stages, flexure mechanisms, kinematic interfaces, sensor modules, thermalstabilized structures, and nanopositioning components.

  • Analyze and optimize system performance using structural dynamics, vibration analysis, stiffness modeling, thermal modeling, and tolerance management.

  • Develop mechanical concepts that support high throughput, high stability, and nanometerlevel measurement accuracy.

  • Own mechanical work packages endtoend, from concept development and FEA validation to supplier engagement, prototyping, and integration in NFI’s metrology tools.

  • Collaborate closely with mechatronics, controls, electronics, and systems engineering to ensure mechanical designs support full systemlevel performance.

  • Support system integration and troubleshooting, resolving complex mechanical challenges through hands-on testing and rootcause analysis.

  • Work with manufacturing, suppliers, and assembly teams to ensure your designs are buildable, repeatable, and cleanroomready.

  • Contribute to team ways of working by sharing lessons learned and helping develop sustainable engineering practices. You take the lead in design desicisions and mentoring others in the team.
