Electrical Engineer - Power Electronics

Triton Systems • Chelmsford, MA

5d • Hybrid

About The Position

Triton Systems is seeking a hands-on electrical engineer with a passion for power electronics to join their Ocean Systems and Metals/Advanced Manufacturing group. This role involves developing marine systems from initial concepts through prototype demonstrations and product commercialization. The Ocean Systems group focuses on underwater vehicles (UUVs), surface vehicles (USVs), Launch & Recovery Systems, underwater products and their subsystems, as well as systems for submarines and autonomous anchor systems for defense, energy, and commercial sectors. As a Power Electronics Engineer, you will be responsible for designing and building the power conversion, motor control, and electrical systems for these platforms. Innovation and technical problem-solving within a multidisciplinary team of researchers will be a significant part of your work.

Requirements

• Bachelor's degree in electrical engineering or a related discipline (advanced degrees are a plus).
• 1–6 years of relevant experience (recent graduates and early-career engineers are encouraged to apply).
• Foundational knowledge of power electronics and power conversion (DC-DC, AC-DC, transformers).
• Familiarity with single and three phase AC power (120–480 VAC) and low-voltage DC (12–48 VDC).
• Ability to read, create, and interpret electrical schematics and wiring diagrams.
• Familiarity with standard electrical practices and electrical standards.
• Hands-on aptitude with electrical assemblies, wiring, and prototyping.
• Comfortable using basic hand tools and electrical test equipment in a lab or prototype environment.
• Interest in or exposure to control systems, since power electronics work is closely paired with controls.
• Ability to manage multiple projects and priorities simultaneously.
• Strong written and verbal communication skills.
• Collaborative mindset and commitment to project success.
• U.S. citizenship required, with the ability to obtain a U.S. security clearance.
• Interest in or exposure to industrial automation and advanced manufacturing systems (robotics, motor drives, welding equipment).
• Willingness to travel for field commissioning and demonstrations, including austere or expeditionary sites.

Nice To Haves

• Experience building electrical control panels using DIN-rail mounted components.
• Experience selecting and sizing COTS electrical components (power supplies, transformers, contactors, breakers, terminal blocks, etc.) for currents up to ~200 A AC and ~30 A DC.
• Experience with motor control and motor drives (e.g., VFDs).
• Experience, coursework, or interest in developing a working understanding of metals processing equipment integration or large-format manufacturing.
• Experience with high-power industrial equipment such as welding power sources, process gas heaters, or large VFD and servo drive systems.
• Familiarity with generator-powered or off-grid electrical design, including power quality on non-utility sources and load management.
• Familiarity with NFPA 79 / IEC 60204-1 industrial machinery electrical standards.
• Familiarity with machine functional safety (ISO 13849) and robot cell safety (ISO 10218 / RIA R15.06).
• Awareness of combustible metal dust requirements (NFPA 484) and associated hazardous-location electrical design.
• Familiarity with MIL-STD-810 environmental and MIL-STD-461 EMI/EMC design practices.
• Experience with industrial fieldbuses (EtherNet/IP, PROFINET, EtherCAT) and digital interfaces to welding or process power sources.
• Experience with thermal design and heat rejection for high-heat-load enclosures or containerized systems.
• Familiarity with safety circuit design, including E-stops, safety relays, indicator lights, and pilot devices.
• Familiarity with industry electrical standards and qualifications (e.g., UL 508A, NEC/NFPA 70, NFPA 70E, or similar).
• Interest in helping grow our electrical design capability - we currently use Visio for diagrams and see an opportunity for the right person to help establish and mature a dedicated electrical CAD workflow (AutoCAD Electrical, EPLAN, SolidWorks Electrical, or similar).
• Familiarity with control electronics, PLCs, HMIs, or sensors.
• Experience with electrical troubleshooting and root-cause analysis.
• Familiarity with thermal management and power dissipation in electrical enclosures.
• Experience designing for harsh or marine environments.

Responsibilities

• Design power electronics solutions including DC-DC, AC-DC, and transformer-based power conversion based on technical requirements, specifications, and proposal objectives.
• With mentorship from senior engineering staff, design 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+ kW.
• Design 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 compatibility.
• Integrate motor drives, welding power sources, robot controllers, and process instrumentation (pyrometers, thermal cameras, feed monitoring) into automated deposition cells.
• Design safety circuits and zoned E-stop architectures for robotic manufacturing cells operating inside ISO containers.
• Address thermal management, dust and moisture ingress, and EMI mitigation for high-power electrical systems in sealed containerized enclosures.
• Support field commissioning, acceptance testing (FAT/SAT), and troubleshooting of containerized systems at demonstration and deployment sites.
• Design and build electrical control panels using DIN-rail mounted components for systems operating on 120–480 VAC single and three phase power.
• Create and maintain electrical schematics, wiring diagrams, and panel layouts.
• Select and size commercial-off-the-shelf (COTS) electrical components from a variety of vendors to meet product requirements (breakers, contactors, terminal blocks, power supplies, transformers, safety buttons/lights, etc.).
• Develop power and motor control circuits and support system-level integration.
• Design PCBs in Altium to support power and control electronics.
• Collaborate closely with controls engineers, since power electronics are paired with control electronics in our systems.
• Build, wire, and assemble prototype electrical systems hands-on in a lab and prototype environment.
• Bench-test, troubleshoot, and validate electrical systems using available test equipment (oscilloscopes, power supplies, load equipment, multimeters, etc.).
• Develop, document, and maintain engineering procedures and technical standards.
• Plan, execute, and iterate testing activities in laboratory and field environments.
• Collaborate with multidisciplinary engineering teams to achieve design goals.
• Contribute to technical proposals and solution development for customer needs.
• Present technical progress and results to internal teams and customers, including non-technical audiences.
• Prepare periodic technical and progress reports for ongoing projects.
