Job description

• Maybell Quantum is redefining the future of computing. As a venture-backed quantum hardware innovator experiencing rapid growth,we'rebuilding technology that will transform industries for decades to come. Quantum computers will be as transformative to the next 30 years as the internet was to the last 30. Our team is creatingthehardware foundation to make this revolution possible.
• Maybell Quantum isestablishingits first operations facility in Singapore, and we are seeking a Plant Manager to build and run the production operation inside it. This is a hands-on manufacturing leadership role: you will lay out and qualify the production lines, hire and develop the production and quality team, and take the line fromfirst-articlebuild to repeatable, on-schedule output. Reporting to the General Manager, Singapore, you will own manufacturing execution at the site — output, yield, cost per unit, and shop-floor safety — while the GM owns the facility, the entity, and the regional supply base. You will work closely with our US manufacturing organization to transfer proven processes and hold both sites to a single build standard.
• What You'll Do
• As Plant Manager, you will own manufacturing execution at Maybell's Singapore site across four workstreams:
• Lay Out the Line: Design the production and test layout within the facility, specify tooling, fixtures, and equipment, and drive installation and qualification alongside the GM's build-out plan.
• Transfer the Process: Execute the transfer of manufacturing, test, and inspection processes from our US site, qualifying the Singapore line against global build standards.
• Build to First Article: Lead first-article build and validation of Maybell's dilution refrigerators, closing out findings beforeramp.
• Ramp to Rate: Take the line from first article to sustainedrate production, improving cycle time, yield, and labor efficiency at each step.
• Daily Production Operations
• Own Output: Hold accountability for on-time delivery, yield, throughput, and cost per unit against the site plan.
• Run the Schedule: Build and manage aggressive production schedules, balancing capacity, material availability, and labor across the floor.
• Manage Materials at the Line: Own shop-floor inventory accuracy, kitting, and consumption, and flag supply risk early to the GM and regional sourcing.
• Document the Work: Develop andmaintainwork instructions, routings, and production documentation for a newly trained workforce.
• Build the Production Team: Hire, onboard, and develop production engineers, technicians, and supervisors as the site scales from the first hire onward.
• Train for Complex Assembly: Establishtraining, certification, and skills matrices for hands-on assembly of complex cryogenic hardware.
• Lead from the Floor: Set daily and weekly operating rhythm — shift handoffs, production meetings, escalation paths — and stay hands-on with the hardware.
• Partner Globally: Work directly with the US manufacturing and engineering teams onbuildstandards, tooling, and DFM feedback.
• Quality, Safety & Continuous Improvement
• Execute Quality at the Line: Implement inspection plans, nonconformance handling, and traceability, and own first-pass yield and escape rate.
• Own Shop-Floor Safety: Enforce safe work practices and site EHS procedures on the floor, in line with the GM's site-level EHS and regulatory framework.
• Drive Improvement: Lead continuous improvement across safety, quality, cost, and throughput, using structured problem solving and lean methods.
• Improve the Product: Feed manufacturing and field learnings back to engineering to improve system design and manufacturability.

Who You Are
