Winixx Inc. is a New York-based technology holding company operating a portfolio of over 30 SaaS platforms across freight, fleet management, financial infrastructure, and market intelligence. Founded with a mission to modernize fragmented and underserved industries, Winixx builds technology that removes inefficiencies, creates transparency, and puts more value in the hands of the people doing the actual work. Our flagship products include Winixx Freight, a next-generation load board with embedded instant payment;

fleetOS, a comprehensive fleet management and roadside assistance platform; and Baron Meddy Financial, our financial infrastructure arm facilitating capital deployment, escrow, and M&A advisory across verticals. Winixx is headquartered in Atlanta, Georgia, with remote teams operating nationwide.

Injection mold tooling is one of the highest-stakes capital investments in hardware product development — a production mold for a complex enclosure can represent $50,000 to $200,000 of upfront investment and a three-to-six-month lead time, and a tooling error discovered after mold completion can mean expensive rework, schedule delays, and in the worst case, a scrapped tool. The Tooling Engineer at Winixx is responsible for ensuring that never happens — that every mold, jig, fixture, and production tooling asset is designed correctly, built to specification, qualified rigorously, and maintained properly throughout its production life.

• Define tooling requirements for all fleetOS hardware programs based on mechanical design specifications, production volume targets, dimensional tolerance requirements, and material specifications, documenting requirements in formal tooling specifications that guide vendor design activity
• Manage the full tooling development lifecycle from vendor selection through production qualification, coordinating tooling design reviews, fabrication milestones, trial runs, and first article inspection with tooling vendors
• Review and approve tooling design proposals from vendors, evaluating gate locations, runner systems, cooling circuit designs, ejection system configurations, and parting line strategies against product design requirements
• Commission and interpret mold flow simulation analyses, identifying filling imbalances, weld line locations, shrinkage patterns, and cooling efficiency issues that require tooling design modifications before fabrication
• Coordinate and manage first article inspection (FAI) for all tooled components, defining measurement plans, working with metrology resources to measure critical dimensions, and formally dispositioning FAI results
• Maintain a comprehensive tooling inventory management system that tracks tool location, cavity count, shot count, maintenance history, scheduled maintenance intervals, and remaining useful life for all production tooling assets
• Develop and enforce tooling maintenance standards and preventive maintenance schedules that preserve tool condition and dimensional capability throughout the production life of each product
• Negotiate tooling costs, lead times, and warranty terms with tooling vendors, ensuring that Winixx obtains competitive pricing while maintaining quality standards and schedule commitments
• Drive tooling cost reduction through tooling design optimization, family mold configurations, shared tooling components, and strategic consolidation of tooling across similar product variants
• Manage tooling change activities associated with engineering change orders, assessing the tooling impact of proposed design changes and managing vendor execution of approved tooling changes

• Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Plastics Engineering, or a closely related engineering discipline
• 2+ years of professional tooling engineering experience working with injection mold tooling, sheet metal stamping tooling, or die casting tooling in a production hardware environment
• Demonstrated experience managing tooling vendors through the complete tooling development cycle from design review through production qualification
• Strong working knowledge of injection molding process fundamentals including material flow, packing, cooling, shrinkage, and ejection, with the ability to evaluate tooling designs and identify design risks before fabrication
• Proficiency with mold flow simulation interpretation — the ability to read, critically evaluate, and draw meaningful…
