Responsibilities
Design and build novel tooling, fixtures, and integration aids using CAD software to support R&D activities, prototype builds, and test campaigns
Collaborate with structural, manufacturing, and test engineers to define tooling requirements for one-off and low-rate development programs
Partner with internal and external machine shops to rapidly fabricate prototypes, with a focus on agility, adaptability, and proof-of-concept demonstration
Explore and evaluate emerging fabrication methods and advanced materials (e.g., additive manufacturing, composites) to push the boundaries of tooling performance
Conduct tooling trials, experiments, and validations to inform design refinements and accelerate technology maturation
Continuously identify opportunities to simplify, automate, or improve prototype tooling to enhance speed, accuracy, and repeatability in R&D workflows
Provide innovative solutions to complex integration and assembly challenges, often where no precedent exists
Develop and maintain clear documentation of CAD models, experimental data, and usage guidelines to support knowledge transfer and future scaling
Ensure all tooling meets ergonomic, safety, and operational requirements appropriate for development environments
Act as a bridge between engineering and prototype build teams, resolving tooling-related issues quickly to keep R&D milestones on track
Qualification
Required
