Company

hirify.global is a fusion energy startup founded in 2019, developing clean energy through advanced laser-driven fusion experiments with a team of scientists, engineers, and entrepreneurs in Munich and Colorado.

What you will do

• Design precision mechanical components, assemblies, fixtures, and positioning systems for optical and experimental diagnostics.
• Create and maintain 3D CAD models, manufacturing and assembly drawings, bills of materials, GD&T documentation, and tolerance analyses.
• Select materials, components, fabrication processes, and suppliers for precision, cleanliness, vacuum compatibility, thermal stability, and vibration requirements.
• Coordinate manufacturing and procurement, review supplier documentation, resolve fabrication issues, and inspect delivered components.
• Perform mechanical assembly, alignment, integration, and functional testing of diagnostic equipment.
• Support installation, commissioning, troubleshooting, design improvements, configuration control, verification records, and technical handovers with multidisciplinary teams.

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, Mechatronics, Precision Engineering, or a related discipline.
• Practical experience designing and delivering precision mechanical devices, instruments, or optomechanical assemblies.
