IonQ is seeking a Senior Mechanical Engineer to join the R&D team in Geneva. You will design, validate, and continuously improve mechanical enclosures and subsystems that integrate optical and electronic components for quantum computing products.
You will own mechanical solutions from early prototyping through industrialized product release, with a focus on delivering compact, robust, and cost-effective designs. Your work ensures compliance with dimensional, thermal, and manufacturability requirements, including for demanding cryogenic systems.
Key responsibilities include:
- Own mechanical design from prototype to industrialized product, including CAD documentation, assembly bring-up, and validation testing
- Drive thermal management (heat sinking, conduction/convection, interfaces and materials), dimensional stability, and manufacturability through design, simulation, and optimization
- Perform thermal simulation to predict temperatures, gradients, and heat flows; correlate models with lab measurements and iterate designs accordingly
- Translate requirements into detailed designs and verified assemblies through 3D modeling, documentation, and engineering calculations
- Collaborate closely with optical, electronic, and system engineers to optimize interfaces and block specifications
- Engage with external suppliers to prototype and manufacture parts efficiently
- Help improve design practices, promote rigorous engineering approaches, and support multiple projects as a mechanical subject-matter expert
Required qualifications: Bachelor's or Master's degree in Mechanical Engineering, Microtechnology, or equivalent; at least five years of relevant experience in mechanical design and product development; hands-on experience designing with sheet metal and/or machined parts; strong ability to develop thermal dissipation solutions.
