Mechanical Engineer – CAD & Engineering Support (Laser Fusion)

Location: Darmstadt, Germany; full-time office-based role.

Company

hirify.global is an early-stage clean-energy company developing laser-driven inertial fusion for commercial-scale clean power, with operations in Germany and the US.

What you will do

• Create detailed 3D models and 2D engineering drawings using Autodesk Inventor or an equivalent 3D CAD tool.
• Produce manufacturing and assembly drawings, layout models, parts lists, BOMs, drawing registers, and complete technical documentation packages.
• Maintain CAD models and documentation throughout project lifecycles while applying consistent CAD standards, drawing conventions, and version control.
• Support mechanical design for vacuum chambers, laser-system integration, diagnostic structures, and facility infrastructure.
• Identify and resolve CAD assembly clashes, interface issues, documentation gaps, and inconsistencies before delivery.
• Review supplier documentation, resolve technical queries, and collaborate with mechanical, electrical, controls, and systems engineers on integration.

Requirements

• Mechanical engineering capability with the ability to translate design intent into accurate models, drawings, and structured engineering documentation.
• Highly detail-oriented and methodical approach to CAD modelling, drawing production, and document control.
• Ability to manage concurrent drawing and documentation tasks while maintaining quality and delivery focus.
• Clear communication with senior engineers, suppliers, manufacturers, and multidisciplinary project teams.
• Proactive identification of design clashes, interface risks, incomplete information, and documentation gaps.
• Ownership of outputs, revisions, technical queries, actions, and design updates.
• Comfort working collaboratively across different engineering disciplines and technical requirements.
• Commitment to engineering standards, CAD conventions, and version-control practices.

Nice to have

• Experience with vacuum systems, chambers, precision mechanical assemblies, laser or optical integration, or scientific instrumentation.
• Familiarity with PDM or PLM systems, CAD data management, document control, and structured version control.
• Knowledge of design for manufacture and assembly, supplier drawing review, prototype build support, and commissioning.
• Understanding of GD&T and engineering drawing standards such as ISO or DIN.
• Experience in experimental physics, research, advanced engineering, or other multidisciplinary technical environments involving integrated, manufactured, and tested mechanical systems.
