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.

^{About the role}

[The seniority/title is determined by job-related skills, experience, and evaluation after the interview.] 

We’re hiring Product Builders to shape the future of marketing for agents — where AI agents are no longer tools, but active participants in how products are built, decisions are made, and value is delivered.

AI agents are fundamentally reshaping:

• how products are built (AI-native, faster, more iterative)
• how marketing flows work (agent-driven discovery, decisioning, and execution)
• how brands and customers communicate (from campaigns → conversations → autonomous interactions)

This shift unlocks a new wave of opportunities — to redesign workflows, reimagine user experiences, and build entirely new product categories.

This is not a traditional PM / designer / engineer / GTM role.

You’ll operate as a builder at the frontier, using vibe coding, AI tools, and rapid prototyping to explore and ship products in this emerging space. You won’t just define what to build — you’ll build, test, and evolve it.

What you’ll do

Build, not just define

• Design and ship products — where agents discover, decide, and act on behalf of users.
• Ship fast, learn fast — iterate based on simulation or real usage.

Own problems end-to-end

• Identify meaningful problems worth solving (clear “why this matters”).
• Drive from discovery → prototype → launch → iteration → scale.

Operate with high agency

• Don’t wait for perfect clarity — create momentum, test hypotheses, and move forward.
• Take ownership of outcomes, not just outputs.

Redesign how brands and customers interact

• Explore new interaction models: agent-to-agent, human-in-the-loop, and autonomous workflows.
• Reimagine marketing workflows as agent-driven systems, not static funnels.

Focus on what truly matters

• Identify the core 1–3 things that make the product valuable, and execute them exceptionally well.
• Avoid overbuilding — prioritize signal over noise.

Collaborate to ship impact

• Work closely with engineering, design, data, and GTM as co-creators.
• Continuously refine based on real-world feedback and data.

What we’re looking for

We’re looking for experienced, high-agency product builders who thrive in new, undefined spaces.

Core traits

• Builder mindset: you ship, iterate, and learn quickly.
• High agency: you don’t wait — you create momentum.
• Strong product taste: you know what good looks like and push toward it.

Experience

• 3–8+ years in product, engineering, startup, or builder roles.
• Experience shipping products end-to-end (0→1 or 1→n) with multiple showcases, with learning and problems to share.
• Exposure to AI-native products, LLMs, or automation is required.

Skills

• Comfortable operating in ambiguity and fast-changing environments.
• Hands-on with prototyping (no-code, low-code, or code).
• Strong prioritization and product judgment.

Mindset

• You believe the future is being built now — and you want to build it.
• You learn by doing, not waiting.
• You care about real customer impact.

Bonus points

• Experience with AI agents, agent workflows, or automation systems
• Familiarity with marketing automation, CRM, or customer engagement platforms
• Experience with building AI products
• Background in startups or 0→1 product environments
• Technical background (engineering, data, etc.)

Why join us?

We’re at the start of a major shift: From marketing to users → marketing for agents. The way products are built, how decisions are made, and how brands interact with customers is being rewritten — and we’re building at the center of it. This means:

• New product categories
• New interaction models
• New ways to drive ROI

There are countless opportunities to create value for our customers in this wave — and we’re looking for builders to explore and capture them.

What success looks like in the first 6 months

• You’ve shipped multiple prototypes or products in the marketing-for-agents space with business impact
• You’ve identified and validated at least one high-impact opportunity in this new paradigm
• You’re operating as a trusted builder, turning ideas into real outcomes
• You’ve helped redefine how agent-driven marketing workflows should work
• Your work has contributed to shaping Appier’s direction in AI agents and agentic marketing
