About the Role

Partner closely with the lab manager to turn ideas into physical hardware rapidly, utilizing 3D printing, CNC machining, and quick-turn development builds for fast learning cycles. This role emphasizes rapid iteration across multiple concepts, quick decision-making, and getting functional prototypes to the team for evaluation.

Responsibilities

• Design mechanical parts and assemblies in CAD, moving quickly from concept sketch to a build-ready file.
• Partner day-to-day with the lab manager to plan and execute rapid prototyping spins using 3D printing (FDM/SLA/SLS), CNC machining, laser cutting, and other quick-turn development materials and processes.
• Choose the fastest path to a testable prototype, considering the right process, material, and fidelity for the question being answered.
• Design for manufacturability and printability/machinability from the outset, identifying potential issues early.
• Build, assemble, and bench-test prototypes, demonstrating comfort in a lab/shop environment.
• Manage multiple concurrent design threads and re-prioritize based on incoming test results.
• Maintain concise documentation, including revisions, BOMs, and test notes, to ensure traceability alongside iteration speed.
• Collaborate with electrical, firmware, and product teammates to incorporate their constraints into subsequent design iterations.

Requirements

• Strong, demonstrable CAD skills (SolidWorks, Fusion 360, Onshape, or similar) enabling quick and clean modeling of complex parts and assemblies.
• Hands-on experience with 3D printing and CNC machining, including practical knowledge of their capabilities and limitations.
• A proven track record of fast prototyping cycles, with examples of taking concepts to physical hardware in days rather than months.
• Working knowledge of materials selection (plastics, metals, common development stock) for both prototyping and production intent.
• Comfort in a physical lab/shop environment, with a preference for hands-on machine operation.
• Strong instincts for design for manufacturability (DFM) and design for assembly (DFA).
• Experience with additional fabrication methods such as laser cutting, sheet metal, vacuum forming, and urethane casting is a plus.
• Basic GD&T and tolerance-stack fluency is a plus.
• Prior experience in a startup, robotics, hardware R&D, or similar fast-iteration environment is a plus.
• Familiarity with PDM/version control for CAD files is a plus.
