• Translate system and customer requirements into robust power architectures, electrical specifications, and actionable design plans.
• Design, simulate, analyze, and verify isolated and non-isolated AC/DC and DC/DC converters, battery chargers, and power-management/distribution circuits.
• Perform detailed power analysis, including regulation and ripple, efficiency, thermal performance, magnetics, control-loop stability, EMI/EMC, transient response, and environmental design margins.
• Lead hands-on hardware integration, debugging, and verification using oscilloscopes, phase/gain analyzers, electronic loads, signal generators, DMMs, and AC and DC power supplies.
• Partner with manufacturing and suppliers to improve producibility, manage component obsolescence and long-lead risks, and resolve issues through RCCA and Failure Review Boards.
• Support technical proposals, trade studies, cost/schedule assessments, and new-business concepts.
• Coach junior engineers and communicate technical recommendations to program leadership, customers, and review boards.

Required Qualifications

• Bachelor's Degree and a minimum of 6 years of prior relevant experience in Electrical Engineering, Physics, Mathematics, Computer Science, or another relevant STEM field or Graduate Degree and a minimum of 4 years of prior related experience

• Experience developing qualified power hardware for defense, cyber, and other mission-critical applications
• Experience working with manufacturing and production teams in a program environment
• Experience with Root Cause Corrective Action (RCCA) and Failure Review Boards (FRB)
• Experience generating and presenting technical material to program leadership, customers, and review boards
• Strong written, verbal, interpersonal, and cross-functional collaboration skills
• Experience serving as a subcontract technical representative, including supplier evaluation, SOW development, and technical oversight
• Experience with ECAD and analysis tools, including LTSpice, PSpice, Cadence, Siemens Xpedition, Mathcad, MATLAB, and Python
• Experience integrating firmware/software with hardware in lab and system environments
• Experience interpreting high-level requirements and developing power architectures
