The Jewelry Supervisor is the first-line leader responsible for the safe, timely, efficient, and quality-focused performance of the Jeweler work cell. The Supervisor translates the production plan into daily execution, provides technical direction across the cell, develops team capability, and is accountable for safety, quality, delivery, productivity, cost, and people performance.

This leader builds a culture of continuous improvement and respect for people. They create clear and fair expectations, listen to and develop team members, make problems visible without blame, and use standard work, data, and structured problem solving to improve first-pass yield and flow. Working in partnership with Quality Assurance and the Production Flow & Quality Coordinator, the Supervisor keeps defects close to their source, provides immediate feedback, and strengthens quality at the point of work.

Lead daily tier meetings; translate demand and priorities into a clear shift plan, assign work based on skill and capacity, and adjust staffing and sequencing to protect schedule attainment and customer commitments.

Maintain control of cell WIP and flow using visual management, FIFO and priority rules, standard times of operation (STOs), and timely escalation of constraints, material gaps, technical risks, or forecasted delays.

Own daily performance for safety, first-pass yield, throughput, schedule attainment, rework, aging WIP, finish quality, and labor productivity; establish countermeasures when performance is off plan and communicate progress to leadership.

Ensure safe work practices, proper tool and equipment condition, workplace organization, and prompt reporting and follow-up of safety concerns and incidents.

Provide visible floor leadership and technical guidance across jewelry production, setting, and polishing; help team members overcome job-specific hurdles, condition tools, optimize finishes, and prevent issues from escalating.

Review customer repairs and special orders to determine feasibility, required work, technical risk, production needs, timeline, and cost implications; support accurate estimates and initiate estimate review when major changes occur.

Ensure aesthetic, workmanship, and finish requirements are understood and achieved while protecting high-value and custom work throughout the production process.

• Direct the Production Flow & Quality Coordinator's daily priorities and integrate work movement, incoming verification, in-process checks, job-status control, and defect containment into the cell's operating rhythm.
• Ensure incoming work meets defined acceptance criteria before it enters the cell; do not allow known defects or incomplete information to transfer silently downstream.
• Keep defects with the responsible cell until corrected, provide immediate and respectful feedback at the point of discovery, and prevent repeat defects through documented root-cause analysis and countermeasures.
• Partner with Quality Assurance on standards, inspection plans, certification, calibration, audits, defect coding, escape investigations, and systemic prevention; preserve QA's independent authority over product acceptance requirements.
• Build quality at the source by reinforcing craft self-inspection, successive checks, standard work, and risk-based QA verification rather than relying on repeated end-of-process inspection.
• Maintain accurate job…
