Job summary

Alice & Bob is seeking a Staff Precision Mechanical Engineer to join the Cryo Hardware Development team. You will design and oversee precision mechanical parts and integration hardware, with emphasis on chip-level components, while coordinating with RF engineers, physicists, and procurement.

You will build validation methods, define testing criteria, and promote rigorous engineering practices, bridging hands-on work and methodology to raise the team’s standards.

Qualifications

• A precision-mechanics specialist with a proven track record of solving demanding integration and reliability challenges under tight physical constraints.
• Comfortable splitting their time between hands-on development and methodology work, bringing structure and rigor to the team while staying pragmatic and collaborative.
• Education: Master’s-level degree in Mechanical Engineering, Precision Mechanics, or a related field.
• Languages: Proficient in English; French is a plus.
• Experience: Minimum 7 years in mechanical design and integration, ideally in high-constraint environments (aerospace, satellite, semiconductor, quantum, or scientific instrumentation).

Responsibilities

• Design and develop precision mechanical parts and integration hardware hands-on, and oversee their development when carried out by external partners, with particular attention to chip-level components
• Produce manufacturing drawings with tolerancing and follow parts through fabrication
• Ensure precision, manufacturability and repeatability across iterations
• Anticipate and address mechanical failure modes linked to cryogenic and thermal cycling
• Drive design choices that support scaling from prototype to series production
• Set up and formalize validation methods for mechanical parts and integration components
• Define qualification criteria and testing protocols in collaboration with the team
• Share rigorous engineering practices with the Cryo Hardware Development team
• Act as a technical reference on precision mechanics for the team
