Responsibilities

Co-own the mechanical and process architecture of our proprietary manufacturing system

Evaluate tradeoffs between precision, throughput, serviceability, cost, and long-term scalability

Establish design principles that guide future machine iterations, variants, and upgrades

Make decisions with IP defensibility, reverse-engineering risk, and internal control in mind

Map and refine the full production workflow—from raw hair handling through robotic injection, sealing, finishing, and QC

Architect systems that are modular, repeatable, and resilient under real production conditions

Design processes that support consistent, luxury-grade outcomes at scale

Create and own detailed CAD models, assemblies, and tolerances

Build, test, and iterate prototypes directly on the production line

Fabricate, assemble, and troubleshoot mechanisms from scratch when needed

Translate conceptual ideas into real, working hardware quickly and thoughtfully

Diagnose and improve machine performance across mechanics, motion systems, tooling, and material integration

Design for failure modes, wear, maintenance cycles, and long-term drift—not just initial performance

Improve throughput and consistency without compromising realism or material integrity

Define engineering standards across hair handling, ventilation/injection, sealing, and finishing

Translate tacit knowledge into clear SOPs, documentation, and training materials

Help move the system from founder-dependent to institutionally reliable

Serve as the primary technical counterpart to external consultants and vendors (mechanical, materials, automation)

Evaluate external work critically, ensure alignment with internal standards, and reduce long-term dependency

Translate between high-level intent and technical execution across teams

Scout and test new materials, adhesives, coatings, and mechanical solutions that improve realism, comfort, and durability

Collaborate with materials experts to move experimental concepts into manufacturable systems

Anticipate future production needs and design with expansion in mind
