Senior Mechanical Engineer, Reliability

Role Overview Role: At Oxford Ionics, now part of IonQ, we are building the first practical quantum computer. 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. Responsibilities: 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. Key responsibilities include:

• 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.
