The ideal candidate will be driven by challenges, passionate about aerospace and defense, and ready to make an impact. This position may require occasional travel to collaborate with vendors, support hardware procurement, oversee testing processes, and engage in related activities as needed.

What You Will Do

Conceptualize and implement innovative technical solutions to address a wide range of complex challenges throughout the product lifecycle, including proposal development, advanced design, manufacturing, integration, testing, and support of missiles, launchers, support equipment, and electronics for military programs.
Operate with limited oversight to serve in a Responsible Engineering Authority (REA) role, often performing in a project management capacity for entire subsystems or systems.
Conduct comprehensive mechanical design analyses using engineering principles to ensure design intent aligns with form, fit, and function for specific use applications.
Provide leadership to small teams by leveraging extensive mechanical hardware design expertise in a dynamic, collaborative environment, working across disciplines such as structures, thermal, systems, harness and interconnects, electronics packaging, tooling, and system integration.
Lead mechanical engineering efforts, collaborating with cross-functional teams—including engineering disciplines, operations, supply chain, quality, and external suppliers—to resolve technical challenges and deliver effective design solutions.
Work independently under limited oversight to manage assignments, ensuring timely delivery within scope, budget, and technical requirements.
Participate in design reviews and facilitate trade studies to support data-driven and strategic engineering decisions.
Mentor and provide guidance to less experienced engineers, fostering skill development and contributing to team technical excellence.
