Mechanical Engineer (Vehicle Systems)

Torrance, CA

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

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.

Core responsibilities

  • 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

Basic qualifications 

  • 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

Bonus qualifications 

  • 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 don’t think great work happens by accident. We invest in the people building Arc — because when you’re supported, you do your best work.

    • Base salary: L3: $150,000  L4:$180,000 per year
    • Ownership – Equity in Arc

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
