Mechanical Engineer; Commercial Systems

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 harbor craft.

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.

We’re looking for someone that is excited by our vision and eager for a challenge. We pride ourselves on transparency and operate in a lean, high-trust environment that encourages everyone to take ownership over their domain.

As a Mechanical Engineer on our Vehicle Systems, 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.

• Architecting mechanical, thermal, and fluid systems on the vehicle
• A dynamic split between requirements gathering, specifications, CAD design, hands on prototyping, analysis (FEA, CFD, hand calculations), in-field validation, and production support
• Using a combination of hand calculations, and CAD to engineer parts
• Getting hands on with building and testing
• Interfacing with suppliers and contractors
• Supporting the design of next generation products

• We’re looking for someone with 3–8 years of experience that includes owning complete mechanical systems from initial design through production and is ready to take full ownership of key systems.
• Experience with CAD software packages such as NX or Solidworks
• Experience with modeling software such as Matlab and Simulink
• Hands on project experience
• Excellent grasp of the fundamentals of Mechanical, Thermal, and Fluids Engineering
• 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.
• We expect strong intuition for manufacturing methods, e.g. if you’re handed a part, you know how it was likely made

• Familiarity with high performance electric vehicles, solar cars, Formula SAE, or similar
• Knowledge of modeling software such as Matlab and Simulink
• Firsthand experience working on commercial vessels
• Exposure to sheet metal manufacturing, CNC machining, CAM, and shop tools
• Prior experience in a fast-paced manufacturing setting
• Clear written and verbal communication
• Ability to articulate and defend engineering decisions
• Strong time management skills
• Comfortable pushing at a fast but sustainable pace
• Experience with fluid system designs including pump sizing, fluid dynamics, and NX routings
• Experience creating and detailing engineering drawings, with a solid understanding of GD&T

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.

We move with urgency and build with care. We value these five things above all else:

• Ownership over both your work and the company’s success
• Empathy for colleagues and for customers
• Humility in problem solving and collaboration
• Pragmatism for navigating ambiguity quickly and sensibly
• Inclusion of different backgrounds, opinions, cultures, and perspectives.
