Job description

eleQtron develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.

About the Role:

We are looking for a highly experienced and technically strong Senior Mechanical Engineer (f/m/d) who can take ownership of complex mechanical designs from concept through detailed engineering, manufacturing, assembly, and validation.

This is a hands-on engineering role for someone with strong mechanical engineering fundamentals, extensive practical design experience, and advanced SolidWorks capabilities.

Responsibilities:

• Take technical ownership of complex mechanical components, assemblies, and subsystems from concept through manufacturing, assembly, and validation
• Develop robust mechanical designs for high-precision scientific and industrial equipment
• Create and maintain high-quality SolidWorks parts, assemblies, manufacturing drawings, BOMs, and technical documentation
• Perform tolerance analysis and define appropriate fits, interfaces, geometric tolerances, and dimensional requirements
• Translate system-level requirements into clear mechanical requirements, interfaces, and manufacturable design solutions
• Define manufacturing requirements and work closely with suppliers and Procurement on manufacturability, materials, tolerances, and quality
• Develop, test, and improve prototypes and actively contribute to design reviews and technical decision-making

Required skills:

• BSc or MSc degree in Mechanical Engineering, Mechatronics, Precision Engineering, or a closely related discipline
• Minimum 8 years of professional mechanical engineering experience
• Advanced professional proficiency in SolidWorks is mandatory
• Demonstrable experience designing complex mechanical assemblies, bespoke machinery, or technically demanding systems
• Strong mechanical engineering fundamentals, including manufacturing methods, materials, tolerance analysis, GD&T, DfM/DfA, structural design, and mechanical interface
• Strong ownership of mechanical designs and technical decisions

We value:

• CSWP – Certified SOLIDWORKS Professional certification
• Experience in industries such as scientific instrumentation, semiconductor equipment, aerospace, precision engineering, special-purpose machinery, optics, or similar fields
• Experience with high-precision systems and/or exposure to vacuum, cryogenic, thermal, optical, or vibration-sensitive applications
• Excellent engineering judgment and the ability to identify and improve weak or risky design solutions
• Practical understanding of how components are manufactured, assembled, tested, and serviced

What you can expect from eleQtron:

• Competitive salary: We value our team members and therefore provide remunerations that reflect this, additionally rewarding particular achievements.
• Flexible working hours: We offer personal freedom through a variety of flexible work schedules.
• Team spirit: In our international and diverse team, and with our regular team events, having fun at work is simply part of the game.
