Job summary

Nextgen Technologies Inc. is seeking an experienced electrical system engineer to own the design and integration of HV/LV systems for commercial marine vessels. You will develop topologies, I/O maps, and wiring definitions and write clear functional specs for software teams.

You will lead component selection, supplier evaluation, and perform hands-on testing and debugging across benchtop, HIL, and in-field environments. Sea trials support and occasional travel are expected.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Mechatronics, Systems Engineering, or related field.
• 5+ years of experience in electrical systems integration, hardware development, or system-level engineering.
• Strong understanding of HV/LV electrical systems, power distribution, sensors, and actuators.
• Familiarity with CAN/J1939, Modbus, Profinet, EtherCAT.
• Hands-on debugging HV/LV systems, harnesses, and hardware-software interfaces.
• Experience developing system requirements, I/O allocation maps, interface definitions, and architectural documentation.
• Strong communication skills, both written and verbal, translating hardware requirements into software specs.

Responsibilities

• Owning the design and integration of high and low voltage electrical systems for commercial marine vessels
• Developing and maintaining electrical topologies, I/O maps, and wiring/harnessing definitions
• Writing clear functional specifications and collaborating with the control software team for hardware-software integration
• Leading hardware trade studies, component selection, and evaluating suppliers
• Hands-on testing, troubleshooting, and debugging HV/LV systems in benchtop, HIL, and field environments
• Supporting sea trials to validate systems and ensure feature parity between bench tests and production vessels
• Interfacing with component suppliers, partner shipyards, and vessel operators, including travel (10-15%)

Job description

• Owning the design and integration of high and low voltage electrical systems for commercial marine vessels


• Developing and maintaining electrical topologies, I/O maps, and wiring/harnessing definitions


• Writing clear functional specifications and collaborating closely with the control software team to ensure seamless hardware-software integration


• Leading hardware trade studies, component selection, and evaluating suppliers


• Getting hands‑on with testing, troubleshooting, and debugging HV/LV systems in benchtop, HIL, and field environments


• Supporting sea trials to validate systems and ensure feature parity between bench test setups and production vessels


• Interfacing with component suppliers, partner shipyards, and vessel operators, including occasional travel (10-15% of the time)

Minimum Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Mechatronics, Systems Engineering, or a related field


• 5+ years of experience in electrical systems integration, hardware development, or system‑level engineering


• Strong understanding of HV/LV electrical systems, power distribution, sensors, and actuators


• Familiarity with automotive or industrial communication protocols (CAN/J1939, Modbus, Profinet, EtherCAT)


• Hands‑on experience debugging HV/LV systems, harnesses, and hardware‑to‑software interfaces using tools like multimeters and oscilloscopes


• Experience developing system requirements, I/O allocation maps, interface definitions, and architectural documentation


• Strong communication skills, both written and verbal, with the ability to translate physical hardware requirements into functional specs for software teams


• Ability to take ownership of problems, drive them to closure, and adapt quickly in a dynamic environment

Bonus Qualifications

• Background in industrial automation, automotive EV, marine, robotics, or aerospace electrical architectures


• Knowledge of industrial electrical control panel layouts and design standards


• Experience with Battery Management Systems, either at automotive or BESS scale


• Understanding of ABS, USCG, IEEE, or IEC standards for commercial marine vessels
