About Us
We are a growing modular manufacturing company specializing in volumetric residential and multi-family construction. Our plant delivers high-quality, efficiently built homes using advanced manufacturing processes. As demand accelerates, we are expanding our team and seeking a detail-oriented professional who thrives at the intersection of estimating, accounting, and operational support.

Position Overview
Production & Capacity Planning

• Manage the 26-station flow line at a two-hour station cycle across two shifts (6:00 a.m.–2:30 p.m. and 2:00 p.m.–10:30 p.m., Monday through Friday, with a thirty-minute handoff overlap).
• Convert the sales backlog and master production schedule into 30-, 60-, and 90-day capacity, staffing, overtime, and shift plans; identify capacity constraints before they affect customer commitments.
• Balance the line, break constraints, and hold cycle time as the product mix widens across ADU, single-family, multi-family, and commercial models.
• Own daily production performance: units completed, first-pass yield, rework, and on-time completion against the build schedule.
• Own the Patterson plant operating scorecard, including safety, schedule attainment, units completed, cycle time, first-pass yield, rework, scrap, labor hours per unit, overtime, equipment uptime, inventory accuracy, and cost variance to standard.

Equipment Reliability & Continuous Improvement

• Own plant equipment reliability and preventive maintenance, including uptime, planned versus unplanned downtime, critical spare parts, and root-cause corrective action on recurring equipment failures.
• Lead continuous improvement across the plant using line balancing, standard work, 5S, visual management, root-cause analysis, and other Lean methods to increase throughput and reduce labor hours, scrap, rework, and downtime.

Quality & Field Feedback

• Own module quality through set, wrap, and transport — what leaves the plant must survive the road and the crane.
• Establish a closed-loop process with Project Management, Installation, Engineering, and Customer Service so field defects, installation issues, warranty claims, and transport damage result in permanent corrective action at the factory.

Cost, Budget & Standards

• Partner with the Controller and CFO on the work-center standard cost model covering material, direct labor, and applied overhead by station, and own it operationally.
• Develop and manage the annual plant operating and capital budget; prepare business cases for equipment, tooling, automation, and facility improvements, and deliver approved capital projects on time and within budget.
• Own plant-controllable spend such as direct and indirect labor, consumables, scrap, and utilities.
• Explain variance to standard with root cause and countermeasure, not narrative.

People & Organization

• Build and lead the plant organization across both shifts: production supervision, quality, maintenance, staging, and receiving and shipping.
• Recruit, train, and retain a production workforce in a Central Valley labor market that competes for operations talent.
• Establish tiered daily management — start-of-shift huddles, hour-by-hour boards, and escalation that reaches a decision.

Systems

• Drive disciplined use of Offsight, the Company's ERP system, for production tracking, station sign-off, and QA documentation, with QuickBooks Online as the general ledger.
• Manage production flow through the Offsight Gantt charts: sequence modules across the 26 stations, track progress against the plan daily, and re-plan the schedule when a station slips.
• Serve as the operations owner of routings, work centers, and shop-floor data capture, and lead operations through the migration to a full manufacturing ERP.

Safety & Regulatory Compliance

• Own EHS performance and build a safety culture measured on leading indicators, not only recordables.
• Maintain compliance with Cal/OSHA and California HCD factory-built housing requirements, including in-plant inspection and the approved quality assurance program.

Qualifications

• Bachelor's degree in engineering, operations, construction management, or a related field. Equivalent hands-on experience will be considered in place of the degree.
• Working fluency with ERP or MES systems in a production environment.
• 10+ years in manufacturing operations, with at least 5 running a plant or a major production area.
• Direct experience commissioning, ramping, or significantly re-rating a production line — greenfield startup, new line launch, or a step-change increase in volume.
• Flow-line assembly experience: modular or manufactured housing, RV, marine, bus or truck body, or comparable large-format assembly.
• Understands cost accounting backwards and forwards — standard cost, routings, labor absorption, and variance analysis — and knows how to systematically identify, explain, and drive unfavorable production variances toward standard.
• Fluent in English and Spanish, given the composition of the production workforce.
• Comfortable spending the day on a production floor; onsite in Patterson, CA five days per week.

Preferred Qualifications

• Modular construction, manufactured housing, or homebuilding experience; familiarity with California HCD or a comparable state in-plant program.
• Experience with multi-family or light commercial modular product.
• Lean or Six Sigma certification, with results to point to.
• Prior participation in an ERP implementation or a manufacturing module rollout.
• High-growth or pre-IPO company where the operating infrastructure was built rather than inherited.
• Experience managing hourly production staff across multiple shifts.

Compensation

Base salary range: $150,000 – $200,000, depending on experience, plus an annual performance bonus target of 20–25% of base and participation in the Company's equity program. Full benefits package.
