Electrical Engineer - Power Electronics

About the role

Triton Systems, Inc. is seeking a hands-on electrical engineer with a passion for power electronics to develop marine systems from initial concepts through prototype demonstrations and product commercialization.

Responsibilities

• Design power electronics solutions including DC-DC, AC-DC, and transformer-based power conversion based on technical requirements, specifications, and proposal objectives
• 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
• Create 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
• 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

Qualifications

• Bachelor's degree in electrical engineering or a related discipline
• 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
• 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

Desired Qualifications

• 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)
• Experience with electrical troubleshooting and root-cause analysis
• Experience designing for harsh or marine environments

Benefits

Base Salary Range Is Dependent On Experience And Qualifications

Schedule

Field work and travel, and willingness to go and work at-sea for the day (or a couple of days) is expected. This role also supports field integration and demonstration of containerized manufacturing systems, which may involve travel to test ranges, depots, or expeditionary demonstration sites.

Pay

Due to the nature of our business and information associated with this position, interested candidates must be US Citizens. Triton Systems' Headquarters is located in Chelmsford, Massachusetts.
