• Serve as senior technical authority: Provide design direction and ensure alignment with system-level requirements, performance, cost, and schedule.
• Perform and review advanced analyses: Conduct and validate thermal, structural, and dynamic analyses using hand calculations and FEA tools such as SolidWorks Simulation, ANSYS, and NASTRAN.
• Define architectures and trade studies: Develop and review mechanical architectures, risk mitigation strategies, and design trade studies for high-impact programs.
• Oversee documentation and approvals: Review, approve, and sign off on critical technical documentation, drawings, specifications, and analysis reports.
• Collaborate cross-functionally: Lead mechanical requirements development with systems engineering, electrical, software, manufacturing, and quality teams.
• Lead technical reviews and anomaly boards: Chair design reviews, anomaly resolution boards, and customer-facing technical discussions.
• Support suppliers and external partners: Provide oversight on supplier designs, requirement compliance, and acceptance of delivered hardware.
• Investigate and resolve failures: Lead root cause investigations for complex failures and drive corrective action implementation.
• Mentor engineers and shape best practices: Guide senior and mid-level engineers and promote mechanical engineering standards and lessons learned across programs.
• Support proposals and technology initiatives: Contribute to proposal efforts, technical roadmaps, and long-term technology development strategies.

Benefits

• 401(k) with 3% company match (automatic enrollment)
• Comprehensive medical, dental, vision, HSA & life insurance
• 10 paid holidays + 120 hours PTO (starting in year one)
• Access to ancillary benefits such as critical illness, accident, disability, legal and pet insurance.
