What they're looking for
- BS, MS, or PhD in Mechanical Engineering or a similar engineering field, with demonstrated success providing technical leadership across complex mechanical systems, subsystems, or major program areas
- Repeated experience developing, validating, releasing, and improving complex hardware across multiple design cycles, project types, failure modes, and implementation environments
- Strong system-level mechanical judgment, including the ability to balance performance, reliability, cost, manufacturability, serviceability, scalability, safety, schedule, integration, and business priorities
- Demonstrated ability to resolve ambiguous, cross-functional technical problems where ownership, requirements, evidence, or tradeoffs are not initially clear
- Proven ability to use analysis, testing, data, field learning, production learning, and engineering judgment to make or guide high-consequence technical decisions
- Strong communication and influence skills, including the ability to align stakeholders across teams and levels of the organization around technical strategy, risks, tradeoffs, and recommended paths forward
