Hardware Engineering Intern

About Base

Base is building the foundation of American power. The grid is the largest, most complex machine in the world. Yet it’s aging, struggling to keep up with today’s demand, and is unprepared for our electrified future.

Base is modernizing the grid as the first engineering-led, technology-driven power company. We’re deploying a nationwide network of distributed batteries that strengthens critical infrastructure and saves Americans money.

Our team of engineers, operators, creatives, technicians, and electricians design and deploy systems at speed. If you want to tackle the problem that will define this century and shape the future of American energy, now is the time. Join us.

About the Role

At Base, we’re building the future of residential energy. Our unique battery, power inverter, and interconnection systems are designed from the ground up to deliver affordable, reliable, and resilient power to households that are underserved by today’s aging and overloaded electrical grid.

Unlike conventional energy storage solutions that cost 5–10x more, our vertically integrated approach allows us to deliver larger, more powerful batteries at a fraction of the price. We’re combining innovative hardware, clever business models, and local manufacturing to get this product in the hands of real people–fast.

As a Hardware Engineering Intern, you'll be hands-on with every phase of product development–from early prototyping to production support. You'll work alongside experienced engineers in a fast-paced, highly collaborative environment, solving challenging problems in mechanical and electrical design for cutting-edge batteries, inverters, and microgrid interconnection devices. You’ll learn by doing–and what you do will ship.

What You'll Do

• Collaborate with senior engineers to design, simulate, build, and test electrical and mechanical systems.
• Participate in hands-on prototyping, debugging, and iterative testing of early- and late-stage hardware.
• Support both R&D and production efforts–from first breadboard to high-volume manufacturing.
• Help diagnose and solve real-world performance, thermal, and integration issues.
• Contribute to system documentation, test procedures, and design reviews.

What You'll Bring

• Current junior or senior in an undergraduate program, or a graduate student, in Engineering, Physics, Math, or a related technical field.
• Strong understanding of electrical or mechanical engineering fundamentals (depending on focus).
• Passion for hands-on hardware development and building things that work in the real world.
• For mechanical focus: experience with CAD design (e.g., SolidWorks, Fusion 360, or similar) is a plus.
• For electrical focus: familiarity with schematic capture and PCB layout tools (e.g., KiCad, Altium) is a plus.
• Curious, self-motivated, and eager to work on hard problems with real-world impact.

Why Base?

You won’t be stuck on the sidelines. At Base, interns contribute to meaningful product work that ships. You’ll gain real experience with real stakes–mentored by engineers who’ve built systems at scale across the energy, aerospace, and hardware industries. This is a chance to make a dent in the energy transition, not just study it. Come help us build something better.

Our Values

We’re building a winning culture and we’re looking for people who are up for the challenge. Here’s what we expect from day one:

• In-Person Only: We work full-time in the office. No hybrid. No remote.
• Challenge the Status Quo: Question assumptions. Fix broken systems. Principles > rules.
• Move Fast: Focus on what matters, act quickly, and learn by doing.
• Give & Get Feedback: Be direct, be humble. Challenge ideas–including your own.
• Own the Outcome: Take full responsibility. Deliver results. No excuses.
• Act Like an Owner: Be resourceful, mindful of impact, and committed to the business.
• Be Decisive: Drive clarity. Make bold calls with imperfect info.
• Bring the Intensity: This is not a 9-to-5. We're building something hard which requires real commitment.
