Core Responsibilities

Primary Functions

Produce detailed hand-carved wax models and masters from technical drawings, sketches, or CAD outputs, ensuring every feature (bezel settings, prongs, filigree, shanks, and pavé surfaces) matches designer intent and tolerances required for casting.
Clean, finish and refine 3D-printed wax parts by removing support structures, smoothing layer lines, and restoring fine details so that printed models are indistinguishable from hand-carved masters for production casting.
Interpret technical drawings and CAD files to convert digital designs into accurate wax models, including scaling, sizing for stone settings, and compensating for casting shrinkage and finish allowances.
Create and assemble wax trees and sprue systems optimized for balanced investment casting, minimizing distortion and maximizing yield while following department best practices for sprue placement and thickness.
Sculpt complex features (micro-prongs, milgrain, granulation textures, engraving recesses) using hand tools, rotary instruments, heated wax pens, and specialized carving implements with high precision and repeatability.
Execute wax modifications and rapid iterations during prototyping phases, implementing designer feedback and engineering changes quickly to support product development timelines.
Maintain dimensional accuracy using precision measurement tools (calipers, micrometers, gauges) and inspect wax patterns to ensure compliance with drawing tolerances and casting/finishing requirements.
Prepare multi-component wax assemblies (settings, shanks, decorative overlays) to fit together precisely post-casting and optimize for downstream bench finishing and stone setting operations.
Repair and rework wax patterns and prototypes, matching surface finish and geometry so repairs are invisible in the final casted piece, and document changes for traceability.
Manage wax inventory, including various wax grades, sheets, rod stock, and 3D printing resins, ordering materials proactively and minimizing downtime due to shortages.
Operate and maintain wax-injection machines, wax heaters, vacuum tools, and wax-printing post-processing equipment safely and per manufacturer and shop protocols.
Collaborate closely with casting and bench teams to troubleshoot casting defects that originate from wax patterns (e.g., porosity, misruns, deformation) and implement design or process improvements to prevent recurrence.
Support stone-setting and finishing teams by creating wax patterns with proper seat depths, setting shoulders, and access for setting tools to reduce rework after casting.
Maintain a consistent and reproducible surface finish standard across wax models so that polishing time and bench finishing are predictable and minimized.
Document production times, revisions, and work orders in the shop’s tracking system; provide accurate time estimates for new jobs and log actual hours for continuous improvement and capacity planning.
Adhere to health, safety, and environmental protocols for use of wax materials, solvents, heaters, and cleaning agents; ensure proper ventilation and PPE usage in the carving area.
Train junior carvers and apprentices in hand-carving techniques, tool use, sprueing best practices, and quality standards to raise the overall capability of the model-making team.
Troubleshoot and fine-tune carving and finishing tooling—sharpen blades, replace burs, balance rotary instruments—to sustain precision and reduce scrap rates.
Provide input during design reviews to identify manufacturability issues, recommend minor design changes to improve castability, and advise on cost- and time-saving alternatives while preserving design intent.
Produce high-volume production runs of wax components to meet daily/weekly quotas while maintaining quality and dimensional consistency across batches.
Execute finishing techniques like texture replication, controlled surface roughness, and micro-detailing so that final cast parts require minimal bench rework and polishing.
Maintain clean, organized workstations with proper storage of molds, dies, and soft tooling to extend service life and improve efficiency during rapid setup changes.

Secondary Functions

Assist with post-casting inspection to isolate defects related to wax pattern issues and provide corrective recommendations to design or process owners.
Support prototyping projects by constructing jigs, fixtures, or temporary assemblies for testing new jewelry designs and production flows.
Contribute to continuous improvement projects—proposal writing, time-study input, and pilot testing for new wax materials or 3D-printing processes.
Participate in cross-functional meetings with design, CAD, casting, and finishing teams to align on timelines, quality goals, and technical constraints.
Maintain and update standard operating procedures (SOPs) for carving techniques, tool maintenance, and finishing checklists to capture tribal knowledge and improve onboarding.
Help implement and test new wax grades, resins, or finishing tools and provide feedback on cost, finish quality, and production speed.
Provide support for order prioritization during peak production periods, including flexible shift coverage and coordination of urgent custom jobs.
