Position overview
QuEra Computing Japan is advancing the development of neutral-atom quantum computing systems in collaboration with global engineering teams. We are seeking a Mechanical Engineer to join our growing Japan team.
This is a deliberately broad, hands-on role for someone who likes being close to the hardware. You will do mechanical design as well as hands-on work on the quantum computer — inspecting, assembling, installing, troubleshooting, and fixing — and the local technical point of contact for the Japanese suppliers and contract manufacturers who build our parts.
We are looking for a practical generalist rather than a specialist: comfortable in CAD in the morning, on a machine with a multimeter in the afternoon, and on a call with a supplier about a drawing tolerance the next day. If you want narrow, deep design work, this is not that role. If you want to own the physical reality of a quantum computer on the ground in Japan, it is.
Key responsibilities
Mechanical design and documentation
•
Create 3D CAD models and 2D drawings using Autodesk Inventor, managed in Autodesk Vault.
•
Design parts, brackets, enclosures, and assemblies with forethought toward manufacturing and assembly (DfM/DfA), applying GD&T appropriately.
•
Specify, procure, and prepare prototypes; assist with testing and validation.
•
Produce and maintain technical documentation — design requirements and specifications, drawings, assembly instructions, and test reports.
•
Work with cross-functional and interdisciplinary teams to ensure designs meet performance and manufacturability requirements.
Machine support and site reliability
•
Keep deployed systems running: inspection, assembly, installation, and preventive maintenance of quantum computer modules.
•
Identify performance issues, determine root cause, propose correction options with tradeoffs, and implement the fix.
•
During testing, development, and deployment phases, surface issues early and review problems and proposed solutions with the US team.
•
Perform hands-on technical work as needed — wiring, soldering, basic electrical measurement and troubleshooting with a multimeter, assembly, cleaning, and general lab support. We are a startup and everyone touches hardware.
•
Improve serviceability and reliability of the systems over time, feeding lessons learned back into design.
Supplier and contract manufacturer interface
•
Act as the local technical interface between QuEra engineering and Japanese suppliers and contract manufacturers — alignment on specifications, manufacturability, and timelines.
•
Support the identification, qualification, and onboarding of Japanese suppliers, in partnership with the US Supply Base Engineering and Supply Chain teams.
•
Ensure supplier documentation packages are complete and current: 3D models, drawings, assembly procedures, test procedures, test reports.
•
Support design, procurement, and assembly of parts and enclosures by third-party vendors.
•
Perform incoming part acceptance inspection and drive resolution when parts don’t conform.
•
Lead or support root cause analysis and corrective action for supplier-related quality issues.
•
Help identify high-risk items and acceptable alternate components; support the US team’s risk mitigation planning.
•
Support Engineering Change Orders (ECOs) and supplier transitions with minimal disruption to builds.
•
Support supplier readiness during new product introduction (NPI).
Ways of working
•
Contribute to a culture of engineering best practices — documentation, configuration control, and disciplined change management.
•
Communicate clearly across a distributed, cross-timezone team.
