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 root-cause and preventive thinking to the product.
  • Coordinate with Japanese machine shops and contract manufacturers; translate Boston/UK designs to local standards; support component validation.
  • Apply DfM/DfA and maintain technical documentation — specs, drawings, assembly and maintenance instructions.
  • General hands-on technical work: wiring, assembling, cleaning, plugging light leaks, deburring, small fabrication fixes. We are a startup.

Required Qualifications

  • Degree in Mechanical Engineering or equivalent practical experience.
  • Proficiency in Autodesk Inventor or comparable 3D CAD, with willingness to work primarily in Inventor.
  • Experience designing precision mechanical systems; strong grasp of structural mechanics, tolerancing, materials, manufacturing, and thermal management.
  • Hands-on prototyping and lab experience; comfort with shop tools, benchwork, and installing your own designs.
  • Professional English and Japanese, including “mechanical engineer” Japanese for specifications and supplier communication.

Preferred Qualifications

  • Scientific instrumentation, precision optics, opto-mechanical design; experience with optics, lasers, and laser safety.
  • Thermal management and liquid cooling; power electronics; GD&T; PDM/PLM (Autodesk Vault preferred).
  • DfM/DfA and prior work with machine shops, particularly in Japan; experience in international, distributed engineering teams.

 

 

メカニカルエンジニア — Hardware Integration and Reliability

概要

QuEra Computing Japanでは、現行および次世代の中性原子量子コンピュータと、それを支える設備のメカニカルシステムを設計・試作・統合・保守する、日本における初の専任メカニカルエンジニアを募集します。本ポジションは「設計者」と「実装者」を兼ねるハイブリッドな役割であり、CADで解決策を提案することはもちろん、自ら工具を手に取り、ラボで構築・設置・改良を重ねていくことにも同じくらい意欲的に取り組んでいただきます。課題の特定、修正案の設計、現地での製作調整、設置および検証まで、一連のプロセスをエンドツーエンドで担っていただきます。また、米国および英国のチームと連携しつつ、日本国内の機械加工業者、受託製造業者、NEDO支援先サプライヤーとの現地技術窓口としてもご活躍いただきます。英語および日本語の双方でビジネスレベルの語学力が必須です。

主な職務内容

  • 剛性、振動、熱的安定性に配慮した精密機械アセンブリ(フレーム、マウント、筐体、オプトメカニカルハードウェア、シュラウド等)の設計
  • QuEraの「Gemini」システムについて、現物(as-built)に整合したCADモデルおよび2D図面の更新・管理
  • レーザーおよび電子サブシステム向けの水冷ループ、漏水対策、熱管理システムの設計および設置
  • レーザー安全のためのエンジニアリング対策(ビームシュラウド、ペリスコープ、ビームブロック、遮光筐体)の設計および設置
  • 性能・安全性・人間工学(エルゴノミクス)に関する課題の特定、トレードオフを明示した複数案の提案、修正の実装(補強、メンテナンス手順の整備、ラックへのアクセス性向上 等)
  • 量子コンピュータモジュールの検査・組立・設置、R&D向けサプライヤー部品の単体試験ベンチの構築、製品に対する根本原因分析および予防的アプローチの適用
  • 日本国内の機械加工業者および受託製造業者との調整、ボストン/英国側の設計を日本のローカル標準に落とし込む作業、部品検証のサポート
  • DfM/DfA(製造性・組立性を考慮した設計)の適用、ならびに技術文書(仕様書、図面、組立・保守手順書)の整備および維持
  • 配線、組立、清掃、漏光箇所の塞ぎ込み、バリ取り、小規模な工作・修繕など、現場でのハンズオンな技術作業全般。当社はスタートアップです。

応募要件(必須)

  • 機械工学分野の学位、または同等の実務経験
  • Autodesk Inventorまたは同等の3D CADの実務スキル(主にInventorを使用することに前向きな方)
  • 精密機械システムの設計経験。構造力学、公差設計、材料、製造プロセス、熱管理に関する確かな理解
  • ハンズオンでの試作およびラボでの実務経験。工作機械、ベンチワーク、自ら設計したものを自ら設置することへの抵抗がないこと
  • 英語および日本語のビジネスレベルの語学力。仕様書作成やサプライヤーとのやり取りに必要な、メカニカルエンジニアとしての専門日本語を含む

歓迎要件

  • 科学計測機器、精密光学、オプトメカニカル設計の経験。光学、レーザー、およびレーザー安全に関する経験
  • 熱管理および液冷、パワーエレクトロニクス、GD&T(幾何公差設計)、PDM/PLM(Autodesk Vault推奨)
  • DfM/DfAの実務経験、および機械加工業者(特に日本国内)との協業経験。国際的に分散したエンジニアリングチームでの業務経験

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.
