- Part of a start-up where growth on a company and individual level is the default
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.
- Design in-vacuum electronics cooling systems
-
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 vacuum chambers.
-
Support assembly, alignment, and field deployment of diagnostic devices at remote experimental facilities.
-
Collaborate closely with physicists, electrical engineers, and systems integrators to ensure diagnostic compatibility 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 laser experiments 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, and system 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
-
Proficiency in COMSOL Multiphysics and experience with Geant4, OpenFoam, or other physics codes for shielding and system interaction modeling
-
Experience with Design for Manufacturing (DFM) and Design for Assembly (DFA) practices
-
Prior involvement in transitioning experimental hardware into low manufacturing quantities
