About this role

Mechanical Engineer-Hardware Integration and Reliability Tsukuba, Japan Mechanical Engineer - Hardware Integration and Reliability (Japan) Location: Tsukuba, Japan (AIST) • Department: Hardware Engineering Summary QuEra Computing Japan is hiring our first dedicated Mechanical Engineer in Japan to design, prototype, integrate, and maintain mechanical systems for the current and next generation neutral atom quantum computers, and the facility around them. This is a hybrid designer-builder role: equally comfortable proposing a solution in CAD and picking up tools to build, install, and iterate on it in the lab. You will own problems end-to-end - identify the issue, design the fix, coordinate local fabrication, install and validate it - and serve as the local technical bridge to Japanese machine shops, contract manufacturers, and NEDO-supported suppliers, working alongside teams in the US and UK. Professional fluency in both English and Japanese is essential. Key Responsibilities - Design precision mechanical assemblies - frames, mounts, enclosures, opto-mechanical hardware, shrouds - with attention to rigidity, vibration, and thermal stability. - Update and own CAD models and 2D drawings for QuEra's Gemini system at AIST, to match the as-built machine. - Design and install water cooling loops, leak containment, and thermal management for laser and electronic subsystems. - Design and install laser safety engineering controls: beam shrouds, periscopes, beam blocks, light-tight enclosures. - Identify performance, safety, and ergonomics issues; propose options with tradeoffs; implement the fix (braces, maintenance steps, rack accessibility). - Inspect, assemble, and install quantum computer modules; build unit testing benches for R&D supplier components; apply
