Position Description

The Principal Engineer is a senior technical leadership role responsible for the design, development, and delivery of advanced protection systems that safeguard electrical infrastructure from transient surges, lightning, and electromagnetic pulse (EMP) threats. This position applies advanced mathematical and engineering principles to develop innovative product and system designs that meet stringent performance, reliability, and regulatory requirements.

In this role, the Principal Engineer leads the design, simulation, validation, and documentation of diode‑based surge protection systems for power, data, and RF applications. The position requires deep technical expertise in transient protection, EMI/EMC compliance, and high‑speed signal integrity, with a focus on supporting mission‑critical and highly regulated environments.

The Principal Engineer serves as a technical authority and provides leadership across project teams, guiding complex engineering decisions and ensuring alignment with organizational standards and strategic objectives. This role may influence and direct efforts across multiple engineering disciplines, fostering collaboration and driving successful product development outcomes.

Essential Duties and Responsibilities

• Provide architectural leadership for next‑generation surge protection solutions across power, data, and RF applications.
• Define and drive product and technology strategy, influencing design standards, engineering best practices, and roadmap innovation.
• Perform advanced modeling and simulation (e.g., transient events, EMI/EMC, signal integrity) to inform design decisions.
• Lead prototype development, validation, and formal qualification to industry standards (IEC, IEEE, MIL‑STD).
• Ensure designs meet performance, reliability, regulatory, and safety requirements, including ISR/DoD/ITAR compliance where applicable.
• Oversee design reviews, ensuring technical rigor and adherence to company and industry standards.
• Identify technical risks early and implement mitigation strategies to ensure successful project execution.
• Lead failure analysis, root cause investigations, and corrective actions to improve product reliability.
• Present technical concepts, design results, and solutions to internal teams and external stakeholders.
• Stay current with emerging technologies, industry trends, and regulatory requirements relevant to protection systems.

Education and Experience

• Master of Science degree in Electrical Engineering or similar field.
• 10+ years of experience in Electrical Protection design.
• Deep technical knowledge of surge protection, transient suppression, and EMI/EMC design.
• Experience with materials development and reliability analysis in high‑voltage or surge protection applications (e.g., ceramics, polymers, coatings, or metallization systems) is preferred.
• Expertise in diode technologies (TVS, Zener, Schottky) and high‑speed/high‑power applications.
• Strong experience in RF systems, data line protection, and power distribution networks.
• Proficiency with simulation tools (SPICE, HFSS, CST, ADS) and PCB design tools (Altium).
• Familiarity with MIL‑STD‑461, IEC 61000, and related compliance standards.
• Strong analytical, troubleshooting, and root‑cause analysis skills.
• Experience with lab testing, validation, and EMC test methods.
• Ability to lead complex technical projects and cross‑functional teams.
• U.S. Citizenship or Permanent Residency required for ITAR compliance.

Personal Traits and Characteristics

• Highly organized and detail‑oriented.
• Strong leadership and technical influence.
• Effective communicator across technical and non‑technical audiences.
• Results‑driven with ability to manage multiple priorities.
• Collaborative, innovative, and solution‑focused.

Physical Job Requirements
