The impact you will make

We are seeking an experienced and technically versatile Senior Experimental Engineer to lead the design, assembly, testing, and deployment of advanced diagnostics systems for ultrashort-pulse laser-matter interaction experiments. This role focuses on developing rugged, vacuum-compatible, and EMP-resilient spectrometers and detectors for ion, electron, neutron, and X/gamma-ray measurements in high-field experimental environments.

The ideal candidate will possess both strong mechanical engineering fundamentals and hands-on field experience, capable of transitioning experimental diagnostics into low production while ensuring compliance with international standards.

Your responsibilities

Design and development of mechanical systems for ion, electron, neutron, and X/gamma-ray diagnostics used in ultrafast laser experiments together with scientists.

Experience with vacuum-compatible assemblies using Autodesk Inventor with emphasis on modularity, alignment, and maintenance

Integrate diagnostic systems in harsh environments with strong EMP and electromagnetic interference; develop mechanical shielding, cooling and isolation strategies.

Select UHV-compatible materials, components, and sealing methods for use in experimental vacuumchambers.

Support assembly, alignment, and field deployment of diagnostic devices at remote experimentalfacilities.

Collaborate closely with physicists, electrical engineers, and systems integrators to ensure diagnosticcompatibility with laser systems and target chambers.

• Conduct structural, thermal, and mechanical simulations using COMSOL Multiphysics

Create ISO/DIN/CE-compliant documentation, including technical drawings, BOMs, risk assessments, and safety documentation.

What you bring

• B.Sc. or M.Sc. in Mechanical or Industrial Engineering, or a closely related discipline with 5+ years of industry experience

Demonstrated experience designing and building precision mechanical systems for high-energy laserexperiments or similar research environments

Proficiency with Autodesk Inventor for mechanical design

Hands-on experience with vacuum-compatible systems and UHV materials

Strong understanding of Cooling systems for in-vacuum electronics

Familiarity with ISO, DIN, and CE standards relevant to mechanical safety, manufacturing, andsystem integration

Ability to work independently in both lab and remote deployment settings with minimal supervision

Strong communication skills and a collaborative, problem-solving mindset

What sets you apart

Experience deploying diagnostics in high-intensity laser facilities or similar environments

Familiarity with spectrometer types such as Thomson parabola, time-of-flight systems, or scintillator-based detectors
