Software Engineer Intern

What we’re building

Every idea starts with a problem. Ours was simple: Boats are special — but they’re loud, pollutant, unreliable, and stuck in the past. Gas-powered boats dominate not because they’re great, but because no better option has existed. Until now.

Arc is here to change that. We’re building 100% electric boats from the ground up — quicker, quieter, easier to maintain, and better for the water they ride on. We’re not just swapping gas for batteries. We’re rethinking every detail on the boat — from propulsion and powertrain to software and ownership model — applying first-principles engineering from aerospace and EVs to deliver a better boating experience.

Electric boats haven’t taken over yet. The tech hasn’t been ready. The talent hasn’t been focused here. That’s our opportunity — and we’re moving fast.

Who we’re looking for

We’re looking for someone who’s fired up by our mission and ready to build. You’ll thrive here if you adapt quickly, take ownership, and care about the details.

You will join our Software team as a summer intern from June 15th-August 21st 2026. You will work from our headquarters in Torrance, CA and report to our Manager, Software. Given that we’re a startup, you will be working in a fast-moving, dynamic environment that requires adaptability. That said, here are some responsibilities and qualifications we expect to stay relatively constant for this role.

Core responsibilities

• Contributing to the boat infotainment unit, mobile app, backend, or boat firmware


• Owning a project end-to-end that meaningfully drives the business forward


• Collaborating with members of the software team as well as other stakeholders

Basic qualifications

• Current enrollment in a Bachelor’s or Master’s degree program in Computer Science, or a related field.


• Familiarity with at least one general purpose programming language


• Strong software development fundamentals


• Productive with standard software development tools (an IDE, git, the command line, etc.)


• Strong analytical and problem-solving skills.


• Ability to work collaboratively in a team environment.


• Eagerness to learn and adapt in a dynamic setting.


• Ability to effectively communicate progress and status of your work

Bonus qualifications

• Experience with one of:


• A track record of successful internships


• Comfortable pushing at a fast but sustainable pace


• Enthusiasm for boating and clean energy


• Targeting graduation in 2026 or already graduated. Arc does not require a specific major.

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.

Our values

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.

We want people who share and embody these values. It is vital that our values align - we’d be happy to elaborate on any or all of these during the interview process.

What we offer

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.

• Hourly Wage: $40/hr


• Daily lunches, plenty of snacks, lots of swag, and more


• Boat days – Yes, we actually go out on the water. A lot.


• A chance to define the future of boating
  


• Talented teammates that challenge you to be better


• Access and often input to a wide range of business activities


• An opportunity to have an outsized impact on industry-defining vehicles


• The ability to drive positive environmental change through your work

Hope to hear from you soon!
