Metric Systems LLC is a direct‑hire employer partner dedicated to helping companies connect with the right talent for their open roles. We are not a staffing agency —instead, we work alongside employers to identify strong candidates, streamline the hiring process, and support both sides through each step. Once hired, you become an employee of the client organization directly, ensuring a seamless transition into your new role and long‑term career alignment.
My client is building a Fuze product line within its Weapons & Networked Solutions (WNS) business unit to support next-generation programs including the Terrain Shaping Obstacle (TSO), autonomous ground munitions, and precision guided weapon fuzing. The organization seeks a Principal Systems Engineer with deep, hands-on expertise in Electronic Safe Arm Fuze and Device (ESAD/ESAF) design, verification, and manufacturing to anchor this team and mentor the next generation of fuze engineers.
Responsibilities:
Lead the end‑to‑end development of fielded fuze systems from initial concept through full safety certification.
Prepare, present, and guide fuze designs through WSESRB, NNMSB, and AFSRB review processes.
Work directly with Army, Navy, Air Force, and DoD laboratory teams to advance fuze engineering efforts.
Leverage established relationships across military branches to accelerate approvals, resolve technical issues, and support program success.
Architect and develop ESAD/ESAF components, including ESD, S&A, and firing chain elements, ensuring compliance with MIL‑STD‑1316 and MIL‑STD‑1911.
Build sensing mechanisms that detect critical environmental conditions such as release, setback, spin, and all‑up‑round dynamics.
Create qualification test plans aligned with JOTP, MIL‑STD‑331, and MIL‑STD‑810; conduct environmental testing and perform failure analysis and root‑cause investigations.
Design electrical or electromechanical S&A devices that meet safety, reliability, and operational requirements.
Build and validate electronics for safety‑critical and mission‑critical fuze applications.
Create and qualify capacitor discharge units (CDU) and EFI selections; perform or oversee HERO margin analysis to ensure safe operation in electromagnetic environments.
Qualifications:
Bachelor's degree in Systems Engineering, or a related Science, Engineering or Mathematics field
10 years of relevant experience; or Master's degree, plus a minimum of 8 years of relevant experience.
