Jewelry & Luxury Goods Cost Estimation Consultant

Contract | Part-time | Remote | Mid-senior level

We're looking for an experienced Jewelry & Luxury Goods Cost Estimation Consultant to collaborate with us in validating and strengthening the knowledge architecture of our AI-powered estimation engine. At Naya, we're building a design-led, AI-powered platform that connects product development workflows, from 3D design to costing, planning, and manufacturing conversations. Our estimation engine helps teams generate early-stage manufacturing cost insights from 3D models and related inputs

The ideal candidate brings real-world validation, domain rigor, and deep Jewelry & Luxury Goods costing knowledge into the system, to help advance the estimation engine to become pinpoint accurate and consistent.

The Role

This is not a traditional in-house costing job. This is about shaping how cost intelligence is structured inside an AI-powered platform. The goal is to translate expert judgment into deterministic systems, where the same product, estimated multiple times, returns the same structure and prices within a tight tolerance.

You will help us:

• Document. Build structured skill-based knowledge files that define what accurate Jewelry & Luxury Goods cost estimation requires. This should include decision rules, step-by-step decision logic breakdowns, benchmarks, assumptions, and other relevant material that help map inputs to costs.
• Refine. Upgrade our estimation methodology with frameworks and industry best practices.
• Shape User Experience. Define and sequence the steps that reflect how your industry costing process works, ensuring the end-to-end flow is logical, fast, and easy to navigate for teams using the platform.
• Review. Stress-test AI-generated cost estimations across materials, processes, tooling, labor, and overhead and identify where the system's logic diverges from how an expert would actually reason.
• Validate. Conduct structured testing, constructing a reference product set, generating estimates against known actuals, and iterating on the skill-based documentation to meet accuracy and repeatability targets.
• Strengthen trust. Contribute to case studies, structured reviews, and credibility-building insights that increase confidence in AI-assisted costing.

You will work closely with product and leadership, through knowledge-capture sessions and async document review, to ensure our estimation engine reflects real-world manufacturing logic.

What You Bring(Core requirements)

• A minimum of 3-5 years of hands-on experience in product costing or manufacturing cost estimation within the Jewelry & Luxury Goods industry is required.
• Demonstrated experience building BOM-based costing models with explicit rules for how inputs map to costs, including material yield, labor time, overhead allocation, and tooling amortization.
• Experience building standardized estimation templates or RFQ benchmarking tools.
• Strong working knowledge of materials, fabrication processes, tooling, supply chain dynamics, and value engineering.
• Understanding of rate data origins, published indexes, internal benchmarking, direct quoting, and can articulate provenance, volatility, and confidence level of each number.
• Experience working with engineering and technical teams to translate verbal process knowledge and decision rules into documented form.
• Comfort reviewing 3D models or CAD-driven inputs as costing triggers.

(Vertical Specific knowledge)

• Fluency in jewelry & luxury goods cost structures: precious metal content, spot-price indexing, stone sourcing, grading economics, and labor time benchmarks for setting, polishing, and finishing by construction method.
• Hands-on experience with fabrication technique cost differences across casting, die-striking, and hand-fabrication, and how technique selection affects material waste, labor intensity, and quality positioning.
• Working knowledge of luxury goods cost architecture beyond jewelry, such as leather goods, watches, or accessories, and how brand tier affects acceptable cost-to-retail ratios.
• Familiarity with hallmarking, certification, and compliance costs, including conflict-free sourcing documentation and how certification requirements vary by market.
• Understanding of regional sourcing benchmarks, including how manufacturing location affects cost and where fine jewelry, fashion jewelry, and luxury accessories are predominantly produced.

Who You Are

• Strategic. You think in frameworks.
• Rigor-driven. Assumptions matter to you. You care about the difference between a range and a keyed lookup.
• Clear communicator. You can explain complex costing logic simply, how a number was derived, and what inputs change it.
• Collaborative. You’re comfortable working with product and engineering teams.
• Curious. You’re interested in how AI can enhance, and not replace, expert judgment.

Engagement DetailsPhase 1: Knowledge capture and validation.

Structured sync sessions and active async communications will cover vertical scope, process steps, rate data, and cross-checks.

Phase 2: Refinement and stress-testing.

Enhance skill files, redline data, and perform multiple validation passes against reference product sets, iterating towards low variance, high accuracy, and consistent results across repeated cost estimations.
