Power Systems Engineer

What we’re building

Our vision is to electrify all waterborne vessels, and we're expanding on our success in the recreational market with commercial harborcraft. 

Gas boats dominate today’s marine industry not because of great product offerings but because of a lack of better alternatives. Boaters have grown accustomed to vehicles that feel stuck in the 1980s: unreliable, expensive, loud, noxious, and a nightmare to own and operate. They’re also awful for the water and air they reside in.

By contrast, electric boats are superior in nearly every way: not only are they far more reliable and less costly to operate, but they’re also quieter, quicker, and cleaner, with no fumes or pollutants. However, they’ve been held back by both the technology and the talent to make them truly competitive with gas alternatives. That’s Arc’s opportunity.

Using modern, aerospace- and automotive-inspired techniques, we’re building our hulls, batteries, cooling systems, firmware, and software together to deliver the next generation of watercraft.

Who we’re looking for

As a Power Systems Engineer, you will be working full-time in our Torrance office on the Commercial Systems team reporting to our head of commercial architecture and working on designing new electric and hybrid propulsion systems to make port operations cheaper, quieter, and less emissive.

Core responsibilities

• Owning the design and integration of high voltage systems, including protection and control schemes
• Getting hands-on with wiring, testing, and debugging both high and low voltage systems
• Owning the development and use of bench test systems, ensuring feature parity between bench systems and production vessels
• Contributing to functional spec development, reviews and the proceeding SW/controls feature testing
• Supporting sea trials to validate and certify systems
• Interfacing with component suppliers, partner shipyards, and vessel operators, with occasional travel (5-10% of the time)

Basic qualifications 

• Solid electrical fundamentals and electrical engineering knowledge
• Experience with power electronics and high voltage energy storage systems 
• Experience with automotive and industrial communication protocols (CAN, LIN, Modbus, etc)
• Familiar with MATLAB/Simulink, oscilloscopes, and other specialized tools
• Practical experience designing, building, and troubleshooting hardware in production environments
• Clear written and verbal communication
• Strong time management skills
• Comfortable pushing at a fast but sustainable pace
• Comfortable spending time on boats in the field to collect test data
• We value engineers who take full ownership, apply first-principles thinking, and prioritize technical problems effectively for the most business value

Bonus qualifications 

• Firsthand experience working on commercial vessels
• Understanding of ABS, USCG, and IEC standards for high-voltage and energy storage systems on commercial vessels
• Experience with functional safety (DFMEA, redundancy strategies) for mission-critical systems
• Experience with EMI/EMC and grounding in high-power marine or automotive environments, including filtering and shielding practices
• Familiar with firmware development for unit testing and integration
• Familiar with Linux, LTSpice, Zuken, and Altium

At Arc, we encourage diversity and consider all qualified applicants equally for employment, regardless of background, identity, or status. You’re always welcome to reach out even if you don’t meet many of these qualifications. Passion and aptitude make up for a lot.
