• Perform aggregate calculations and select appropriate components and materials
• Create accurate CAD part and assembly models and drawings, including tolerance stack-up analysis where needed
• Conduct structural analysis and multibody dynamics simulations to validate designs against performance, safety, and reliability targets; define correct FEA inputs and interpret results to guide design decisions
• Develop test cases, set up test environments, execute tests, and prepare detailed test reports
• Based on test outcomes, identify improvement areas, propose design modifications, and plan iterations or further testing until requirements are met
• Communicate design intent to vendors using 3D CAD, 2D drawings, GD&T, and engineering specifications, applying DFM and DFA principles
• Work with vendors and suppliers to develop and scale components to specification
• Collaborate with embedded, controls, and software teams for seamless integration, and with operations teams on sourcing, QC, assembly, and delivery
• Develop and maintain BoMs, SOPs, release notes, change records, and validation reports
• Support root-cause analysis and corrective actions for mechanical issues across prototypes, production, and field returns

Requirements

• Strong capability in aggregate calculations and first-principles problem-solving on complex mechanical challenges
• Expertise in CAD, preferably Solid Edge, producing accurate, high-quality models efficiently
• Deep knowledge of GD&T and proficiency in tolerance stack-up analysis
• Hands-on structural analysis and multibody dynamics experience with tools such as Ansys and Adams
• Strong working knowledge of manufacturing processes such as machining, sheet metal, casting, and welding across multiple materials, and their impact on design decisions
• Hands-on experience designing primary structures, mechanisms, jigs, and fixtures
• Working knowledge of solid mechanics, load cases, and failure mechanisms
• Familiarity with Design Thinking principles for ideation, problem-solving, and product design
• Strong written and verbal communication and the ability to coordinate across multiple stakeholder teams

Good to Have
