Senior Principal Electrical Engineer- Power Systems

Epirus•Torrance, CA

About The Position

The Senior Principal Electrical Engineer will own power systems development for Epirus’s High Power Microwave Phased Array, from conception and prototyping through productization and production. The role works closely with a multidisciplinary engineering team in a fast-paced environment to apply emerging technologies and develop new products. It reports to the Senior Manager of Electrical Engineering. The engineer will lead systems integration and architect electrical designs for power distribution, communications, safety, and other system needs. The role includes hands-on wiring, testing, and debugging of high-power phased-array systems, as well as technical leadership, supplier collaboration, and mentorship of junior engineers. Occasional travel may be required.

Requirements

Degree in Electrical Engineering, Aerospace Engineering, or Systems Engineering.
12 or more years of industry experience, preferably spanning the product lifecycle from concept to field deployment; advanced degrees may be used in place of years of experience.
Ability to articulate and defend technical decisions, with clear written and verbal communication skills.
Knowledge of Jira and Scrum best practices.
Ability to obtain and maintain a U.S. clearance; U.S. citizenship is required to obtain a U.S. clearance.
Ability to travel occasionally.
Must meet applicable ITAR eligibility requirements: be a U.S. citizen, lawful permanent resident, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain required authorizations from the U.S. Department of State.

Nice To Haves

Experience implementing high-voltage power distribution and battery systems up to 800V.
Experience designing and implementing three-phase AC power (120V/208V/240V/480V) and high-voltage DC power subsystems for directed energy systems.
Familiarity with fieldbus and other communication protocols relevant to power subsystems and industrial automation, such as RS485, RS232, CAN, EtherCAT, and Ethernet.
Knowledge of applicable industry standards, such as MIL-STD and IEC standards.
Proficiency in standard practices and design rules for high-voltage/high-power wiring and harness design.
Experience with Design Failure Modes and Effects Analysis (DFMEA) for identifying and mitigating potential system failures.
Aerospace/defense or military experience, or experience in directed energy or a similar industry such as aircraft power, radar power systems, laser systems, or automotive/electric vehicle power.

Responsibilities

Design and prototype critical power electronics subsystems, emphasizing prime power distribution and conversion.
Develop system-level power budgets and coordinate requirements with subsystem design teams.
Create and review engineering analyses, including electric power load analyses (EPLAs), short-circuit hand calculations, power systems studies, voltage drop calculations, lighting calculations, and harmonic analyses.
Lead the design and integration of power electronics subsystems for large-scale phased arrays, from prototype development through full-scale production.
Define organizational standards for high-voltage safety and best practices, and lead safety checks at key integration milestones.
Define and refine technical requirements and specifications for High Power Microwave power subsystems and power distribution and conversion architecture.
Perform hands-on wiring, testing, and debugging of high-power phased-array systems.
Lead power distribution system architecture through trade studies, single-line diagrams, benchmarking, and architecture reviews.
Collaborate with internal teams and external suppliers on component design, testing, and evaluation to meet system requirements.
Mentor junior engineers in power system fundamentals, general design principles, and ruggedization techniques.
