Chief Mechanical Engineer

MUST BE ELIGIBLE FOR TOP SECURITY CLEARANCE

About the Role

We're building next-generation defense systems designed to operate in the world's most demanding environments. As our Chief Mechanical Engineer, you'll lead the architecture, design, testing, and validation of mission-critical hardware that must perform flawlessly under extreme operational conditions.

This is a hands-on leadership role for an engineer who thrives at the intersection of advanced robotics, autonomy, and ruggedized defense systems. You'll own the mechanical engineering function, drive technical decision-making, and work closely with electrical, software, systems, and manufacturing teams to bring cutting-edge products from concept to deployment.

What You'll Do

• Lead the design, development, and qualification of ruggedized mechanical and electromechanical systems for defense applications.
• Own the mechanical architecture of products from early concept through production and field deployment.
• Design systems to meet demanding military and operational requirements, including vibration, shock, thermal, ingress protection, and environmental survivability standards.
• Perform and oversee structural, thermal, vibration, modal, and finite element analyses to validate designs and guide engineering decisions.
• Drive mechanical integration across sensors, actuators, power systems, electronics, wiring harnesses, and embedded hardware.
• Develop comprehensive engineering documentation, including CAD models, drawings, specifications, test plans, analysis reports, and qualification procedures.
• Plan and execute environmental, reliability, and qualification testing to validate performance under real-world operating conditions.
• Lead prototype builds and rapid iteration cycles, working closely with manufacturing and supply chain teams to ensure scalable, cost-effective designs.
• Establish and enforce best practices in Design for Manufacturing (DFM), Design for Reliability (DFR), and product lifecycle management.
• Identify technical risks early and lead cross-functional design reviews to ensure successful program execution.
• Build and mentor a high-performing mechanical engineering team as the company scales.

What You'll Bring

• A passion for building robust hardware systems that perform reliably in harsh and mission-critical environments.
• 10+ years of mechanical engineering experience, including significant experience developing complex electromechanical products.
• Previous experience in robotics, autonomous systems, robotic research laboratories, medical robotics, unmanned systems, or related advanced hardware domains.
• Bachelor's or Master's degree in Mechanical Engineering or a closely related discipline.
• Strong R&D background with a track record of taking products from concept through validation and deployment.
• Expertise in structural, vibration, thermal, and modal analysis using tools such as ANSYS, SolidWorks Simulation, or equivalent platforms.
• Advanced proficiency with modern CAD tools such as SolidWorks, Creo, or CATIA.
• Deep understanding of environmental qualification requirements, including vibration, shock, thermal, humidity, and other military-grade durability standards.
• Experience integrating mechanical structures with electrical and electronic systems, including sensors, actuators, cabling, and embedded hardware.
• Strong understanding of FEA, modal analysis, thermal management, and reliability engineering.
• Proven ability to collaborate across mechanical, electrical, software, systems, and manufacturing disciplines.
• Experience applying DFM and DFR methodologies to complex hardware products.

Preferred Qualifications

• Direct experience developing hardware for defense, aerospace, maritime, or other mission-critical industries.
• Experience qualifying products to MIL-STD-810 environmental test requirements.
• Familiarity with naval shock, EMI/EMC, and related military qualification standards.
• Experience designing systems for shock mitigation, vibration isolation, and structural survivability.
• Knowledge of thermal management, fluid dynamics, and heat transfer in tightly integrated electromechanical systems.
• Experience with rapid prototyping, additive manufacturing, and accelerated hardware development cycles.
• Startup experience or a demonstrated ability to thrive in fast-paced, resource-constrained engineering environments.
• Previous technical leadership experience managing projects, teams, or major hardware programs.
