Job Description

Electrical Engineer - Power Electronics Company SummaryTriton Systems, Inc combines 30+ years of experience with exciting growth and innovation opportunities within the product development and R&D space. We support Government and commercial markets by delivering advanced solutions across applications in defense, security, aerospace, energy, environmental sustainability, and human health. Where we see a larger opportunity, we create new companies to scale these solutions into businesses. Our teams thrive in a collaborative, fast-paced environment where we tackle complex challenges, meet our customers' toughest requirements, and deliver high-impact results on time, on budget and have fun while doing it. Triton's Metals & AM team is also building out custom-integrated advanced metal additive manufacturing systems, e.g., large-format cold spray systems, to address repair, coating and advanced manufacturing needs.Are you Driven to Innovate? Triton Systems develops new, exciting, innovative products for the maritime environment. The Ocean Systems and Metals/Advanced Manufacturing group is seeking a hands-on electrical engineer with a passion for power electronics, interested in developing marine systems from initial concepts through prototype demonstrations and product commercialization.Triton Systems Ocean Systems group develops underwater vehicles (UUVs), surface vehicles (USVs), Launch & Recovery Systems, underwater products and their subsystems. Additionally, the Ocean Systems group develops systems for submarines, autonomous anchor systems for the defense, energy, and commercial sectors. As our Power Electronics Engineer, you will design and build the power conversion, motor control, and electrical systems that bring these platforms to life. Being innovative and providing technical problem-solving within a multidisciplinary team of researchers will be a major part of your work life.ResponsibilitiesDesign power electronics solutions including DC-DC, AC-DC, and transformer-based power conversion based on technical requirements, specifications, and proposal objectivesWith mentorship from senior engineering staffDesign power distribution and conversion architectures for containerized metal additive manufacturing systems, including load analysis and sequencing of high-power process equipment such as gas heaters, spindle drives, and welding power sources totaling 100+ kWDesign electrical systems for operation on tactical generator and shore power, addressing power quality, inrush and soft-start, grounding of separately derived systems, and 50/60 Hz international compatibilityIntegrate motor drives, welding power sources, robot controllers, and process instrumentation (pyrometers, thermal cameras, feed monitoring) into automated deposition cellsDesign safety circuits and zoned E-stop architectures for robotic manufacturing cells operating inside ISO containersAddress thermal management, dust and
