As a Senior Mechanical Engineer on the Reliability Engineering team, you’ll keep our quantum computers running at their best, boosting fleet uptime and cutting operating cost
You’ll work closely with electrical, optical and science colleagues as part of a supportive, collaborative team, updating mechanical designs and managing configuration so their system improvements can land
Your focus will be the live fleet. You will root-cause mechanical, vacuum, cryogenic and thermal faults on running systems, prioritise issues by their impact on uptime, and analyse failed parts to track recurring failure modes
Where a challenge keeps coming back, you will design, prototype and test the solution, then write the assembly and upgrade instructions that bring the new design into existing fleets, working with our operations team to get upgrades implemented into live systems. You will keep the product lifecycle management (PLM) system, build records and engineering change requests (ECRs) up to date so fixes carry into future builds
Root-cause mechanical, vacuum, cryogenic and thermal faults on live systems, prioritising issues by impact on uptime
Design, prototype and test solutions to recurring challenges
Implement mechanical changes that enable electrical and optical improvements
Write assembly and upgrade instructions to bring new designs into existing fleets, and work with our operations team to implement upgrades in live systems
Analyse failed parts, track recurring failure modes and update the PLM system, build records and ECRs so fixes carry into future builds
You will be a mechanical engineer with a strong design background and 4+ years of relevant industry experience. A degree in Mechanical Engineering or a related field, or equivalent practical experience (including apprenticeship routes), is expected
Quantum experience is not required. We will teach you the rest, and if you meet most of this posting and the work excites you, we encourage you to apply
You are proactive and self-directed, happy to ask for input, and comfortable working on systems where uptime matters while collaborating across disciplines
If you meet most of this posting and the work excites you, we encourage you to apply!
Established CAD ability, ideally SolidWorks, plus geometric dimensioning and tolerancing (GD&T) and PLM experience
Experience with cryogenic, vacuum, or optomechanical systems
Structured root cause and failure analysis (e.g. 5 Whys, failure mode and effects analysis)
Ability to explain technical trade-offs across disciplines
