Jobbeschreibung

Facing the challenges of our time - Help us grow and be more impactful!

For more than three decades, CSEM has contributed to demanding European space missions through the development of precision mechanisms, scientific instruments and dedicated support equipment. Our work bridges applied research and flight-oriented hardware development, from early concepts to integrated and tested systems.

The Precision Mechanisms group of CSEM's Instrumentation Business Unit, based in Neuchatel, is looking for a Senior Precision Mechanical Engineer to strengthen its space hardware development activities. We are seeking an experienced, hands‑on engineer who can rapidly take ownership of mechanical developments and contribute across the full lifecycle, from detailed design to assembly, integration, testing and technical problem solving.

Maximum duration contract of 2 years.

Your mission

You will play a key role in delivering precision mechanical hardware for demanding applications. From early concepts and requirements to assembly, integration, and verification, you will transform ideas into robust, manufacturable hardware. As a senior engineer, you will own mechanical work packages, coordinate subcontractors and suppliers, and solve practical engineering challenges throughout the development and qualification process.

Your responsibilities

• Design precision mechanisms, mechanical structures, optomechanical interfaces and custom test equipment. This includes 3D models, technical drawings, interface data, tolerances and manufacturing documentation.
• Prepare procurement specifications, select and coordinate suppliers and subcontractors. Define incoming inspection plans, acceptance criteria, and manage technical clarifications and non-conformances.
• Take technical ownership of mechanical work packages from concept selection through manufacturing, assembly, integration and testing.
• Prepare and execute assembly, integration, including work in cleanroom and contamination-sensitive environments.
• Prepare and execute performance and environmental test campaigns on-site and off-site.
• Contribute to risk analyses, design reviews, failure investigations and root cause analyses.
• Collaborate closely with multidisciplinary teams covering systems, optics, electronics, thermal engineering, analysis, quality and testing.
• Contribute to customer and partner exchanges, technical reviews, project documentation and proposal activities when required.

Your profile

Bachelor's or Master's degree in Mechanical Engineering, Microtechnology or a related field.
