About the Role

As a Senior Mechanical Engineer, you will own the mechanical design of Nimble's robotic platforms, from structures and mechanisms to precision assemblies and production-ready hardware. You will work at the core of machine design, structural analysis, GD&T, materials, and design for manufacturing, collaborating with cross-functional teams to integrate designs into complete robotic systems. This role involves owning designs beyond the initial phase, driving part quality, supporting the supply chain, and reducing costs during scaling from prototype to high-volume production.

Responsibilities

  • Own the mechanical design and architecture of robotic subsystems from concept through production deployment.
  • Produce production-grade engineering drawings with GD&T, including datum schemes, functional tolerancing, and tolerance stack-up analysis.
  • Develop detailed 3D CAD models and assemblies, and drive system-level mechanical design decisions.
  • Perform engineering calculations, hand calculations, structural/stress analysis, and FEA.
  • Design for manufacturability (DFM), assembly (DFA), reliability, serviceability, and cost.
  • Select and integrate mechanical and electromechanical components.
  • Partner with controls, software, electrical, embedded, perception, and manufacturing teams to deliver integrated robotic systems.
  • Lead prototype builds, debugging, root-cause investigations, and field performance improvements.
  • Establish and execute validation plans, reliability testing, and qualification procedures.
  • Support the supply chain across the product lifecycle, including sourcing, supplier selection, and issue resolution.
  • Own part quality for designed components, defining inspection requirements and leading first-article inspections.
  • Drive cost reduction through tolerancing, material, and process choices, value engineering, and design-to-cost.
  • Support the transition from prototype to production, including documentation and manufacturing support.
  • Mentor engineers and contribute to mechanical engineering best practices and design reviews.

Requirements

  • Bachelor's degree in Mechanical Engineering or a related field.
  • 7+ years developing complex mechanical or electromechanical hardware.
  • Deep mechanical engineering expertise: machine design, mechanisms, structural and stress analysis, solid mechanics, materials, and product development.
  • Strong, demonstrable GD&T fluency (ASME Y14.5).
  • Proficiency with 3D CAD tools such as SolidWorks, Creo, or equivalent.
  • Solid understanding of manufacturing processes and their impact on cost and yield.
  • Track record of driving part quality and cost reduction with suppliers.
  • Comfortable interfacing with electrical, controls, and embedded systems.
  • Experience with prototyping, testing, troubleshooting, and system integration.
  • Ability to interpret test data and drive engineering decisions through quantitative analysis.
  • Strong communication skills and ability to work effectively across multidisciplinary teams.
