Company

hirify.global is a fusion energy start-up founded in 2019, developing clean energy technology with a team of scientists, engineers, and entrepreneurs in Munich and Colorado.

What you will do

• Design precision mechanical devices, machines, mechanisms, tooling, molds, fixtures, positioning assemblies, and alignment equipment from concept through production-ready design.
• Define dimensions, datum strategies, fits, tolerance stacks, surface finishes, materials, stiffness, thermal stability, interfaces, assembly sequences, and serviceability.
• Create engineering packages including 3D CAD models, manufacturing and assembly drawings, GD&T, bills of materials, inspection requirements, and technical specifications.
• Manage the manufacturing interface from prototype to finished parts, including process selection, supplier coordination, feasibility, first-article inspection, and nonconformities.
• Support precision fitting, assembly, adjustment, alignment, installation, acceptance testing, commissioning, and technical handover.
• Install, integrate, and commission cooling-water circuits with piping, hoses, fittings, valves, manifolds, sensors, and leak or pressure testing.

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, Precision Engineering, Mechatronics, Manufacturing Engineering, or a related discipline.
• Demonstrated experience designing precision machinery, manufactured devices, complex mechanisms, or tooling and delivering functional hardware with complete drawings.
• Deep knowledge of precision manufacturing, machining, tooling methods, material behavior, fits, GD&T, surface finishes, tolerance chains, and dimensional verification.
• Strong CAD and technical drawing skills, including manufacturing-ready documentation, bills of materials, tolerance analysis, and communication with machinists, toolmakers, metrology teams, and suppliers.
• Hands-on experience across the hardware development cycle, including prototypes, supplier follow-up, inspection, precision assembly, functional testing, and commissioning.
• Practical experience installing cooling circuits and knowledge of piping systems, fluid components, instrumentation, and flow, pressure, and temperature sensors.

Nice to have

• Experience with mold design and manufacturing, injection molds, forming dies, precision toolmaking, or comparable tight-tolerance machinery.
• Experience with precision positioning mechanisms, custom machines, scientific instrumentation, optomechanical devices, or automated precision assemblies.
• Experience interpreting CMM reports, geometric tolerances, surface roughness measurements, inspection plans, and precision assembly or alignment procedures.
• Experience working directly with machine shops and toolmakers, resolving manufacturing deviations, optimizing parts for production, and leading build-to-test iterations.
• Strong ownership, practical problem-solving, and a design-for-manufacture mindset.
• Experience selecting, integrating, and troubleshooting fluid sensors, flow meters, pressure transducers, temperature sensors, and piping hardware in laboratory or industrial cooling systems.

Culture & Benefits

• Purpose-driven work on fusion technology and clean, safe, abundant energy.
• Public transport subsidy, phone bill reimbursement, employee incentive program, and company pension plan.
• Wellpass or complimentary private health insurance and a professional learning and development budget.
• 30 days of vacation plus an additional half day on December 24 and 31.
• Relocation support, a modern office in central Munich, healthy office snacks, and regular team events.
