Custom Design & Matching Bands

• Design custom rings from concept through to final production-ready CAD model, interpreting client briefs, sketches, and reference imagery with accuracy.
• Develop matching band designs that maintain aesthetic and structural continuity with engagement rings and primary pieces - including sizing compatibility, profile alignment, and stone setting coordination.
• Build stone settings (prong, pave, channel, bezel, and combinations) with proper tolerances and structural integrity for manufacturing.
• Design functional components including hinges, clasps, linkages, and connections as required by project scope.
  

Product Development & New Projects

• Partner with the Product Development team to execute CAD models for new collections, prototypes, and special production runs.
• Review design briefs and provide early-stage technical input on constructability, stone sourcing constraints, and production feasibility.
• Deliver complete, split production models ready for casting, finishing, and assembly workflows.
• Provide input on project timelines and flag risks related to complexity or scope changes.
  

Existing Design Modifications

• Modify existing CAD files for design updates, stone size changes, metal variations, and customer-requested customizations.
• Review and repair legacy files received from external designers or vendors to ensure they meet internal production standards.
• Maintain version control and documentation of all modified files.
  

Technical Leadership

• Review Vendor CAD files for technical viability and provide feedback to strategic partners.
• Support and mentor junior CAD staff on software techniques, jewelry construction principles, and production standards.
• Contribute to the development and documentation of CAD best practices and file standards.
  

• Minimum 5-7 years of CAD design experience specific to fine jewelry.
• Expert-level proficiency in Rhino 8 - required.
• Proficiency in Matrix Gold - required.
• Deep knowledge of complex jewelry construction including precious and non-precious metal properties.
• Mastery of creating solid, workable polysurface files; experienced with modifying and repairing mesh objects.
• Demonstrated portfolio of custom ring and matching band designs.
• Strong understanding of production techniques - file splitting, casting preparation, and manufacturing constraints.
• Experience with 3D Coat, ZBrush, or comparable sculpting software is an asset.
• Experience with rapid prototyping / 3D printing is an asset.
  

Microsoft 365

• Expert-level proficiency across the Microsoft 365 suite - including Outlook for managing design briefs, client communications, and vendor feedback; Excel for building and maintaining project tracking tools, design revision logs, and workload dashboards; Word for creating technical specifications, design briefs, and procedural documentation; and Teams for real-time collaboration with PD, production, and management teams.
• Leverage SharePoint and OneDrive to maintain a structured, version-controlled digital library of all CAD files, design references, approved models, and project documentation - ensuring accessibility and continuity across the team.
• Ability to build Excel-based tools to support design pipeline management, including job status tracking, revision histories, and project milestone reporting for senior leadership.
  

ERP & Production Management Systems

• Proficient in using ERP or production management software to manage the full lifecycle of CAD job orders - from initial design brief intake through model delivery, approval, and handoff to production.
• Ability to create, assign, and update job orders within the ERP system, linking CAD deliverables to the correct job references and ensuring that production teams have accurate, up-to-date information on file readiness and design specifications.
• Use the ERP system to monitor job flow across concurrent projects - tracking design stage, revision status, casting readiness, and approval milestones - and proactively communicate delays or scope changes to supervisors and the production floor.
• Coordinate with the production team through the ERP to sequence CAD deliverables around casting house schedules, tooling requirements, and floor workload capacity, minimizing bottlenecks in the production pipeline.
• Able to generate ERP-based reports on CAD output, project throughput, revision frequency, and design reuse to support Manufacturing Excellence reporting and continuous improvement initiatives.
• Experience with jewelry-specific or fine manufacturing ERP systems is strongly preferred; adaptability to the company's existing platform is required.
  

• Excellent spatial reasoning and aesthetic sensitivity for design consistency across custom and standard collections.
• Strong project management skills - able to prioritize and track multiple concurrent design assignments across custom, PD, and modification workstreams.
• Clear communicator with the ability to translate creative direction into precise technical action and articulate design decisions to both technical and non-technical stakeholders.
• Collaborative mindset with the ability to work closely with product development, production, QC, and client-facing teams.
• Comfortable operating as a senior contributor in a high-volume production environment where design quality and delivery speed are both expected
