Senior Mechanical Engineer, Reliability (Quantum Computing)

Location: Oxford, England, United Kingdom

Company

hirify.global develops integrated quantum computing, networking, sensing, and security solutions. Oxford Ionics is now part of hirify.global and is building practical quantum computers.

What you will do

• Root-cause mechanical, vacuum, cryogenic, and thermal faults on live quantum-computing systems and prioritize issues by their impact on fleet uptime.
• Analyze failed parts and track recurring failure modes.
• Design, prototype, and test solutions to recurring reliability challenges.
• Implement mechanical changes that enable electrical and optical system improvements.
• Write assembly and upgrade instructions and work with operations to deploy upgrades into live systems.
• Maintain PLM data, build records, and engineering change requests so fixes carry into future builds.

Requirements

• Mechanical engineering background with a strong design focus and 4+ years of relevant industry experience.
• Degree in Mechanical Engineering or a related field, or equivalent practical experience including apprenticeship routes.
• Proactive and self-directed approach, willingness to ask for input, and ability to work on systems where uptime matters.
• Ability to collaborate across electrical, optical, science, operations, and other disciplines.
• For applicable US technical work, access to export-controlled technology may require verification of U.S. Person status, a necessary license, or confirmation of a license exception.

Nice to have

• Established CAD ability, ideally SolidWorks, plus geometric dimensioning and tolerancing and PLM experience.
• Experience with cryogenic, vacuum, or optomechanical systems.
• Structured root-cause and failure analysis experience, such as 5 Whys or failure mode and effects analysis.
• Ability to explain technical trade-offs across disciplines.
• Quantum experience is not required.

Culture & Benefits

• Collaborative, supportive environment with autonomy, productivity, respect, and opportunities for different voices and viewpoints.
• Base salary, bonus, equity, and benefits package.
• Medical, dental, and vision plans; matching 401(k); unlimited PTO; and paid holidays.
