Manufacturing 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

As a Manufacturing Engineering Intern, you’ll get hands-on experience designing and standing up the processes that make our products real. You’ll work alongside experienced engineers and operators in a fast-paced, highly collaborative environment, supporting everything from early prototype builds to production-scale deployment. You’ll learn by doing - and what you do will directly impact how we deliver affordable energy at scale.

What You’ll Do

• Collaborate with engineers to design and refine processes, fixtures, and equipment for assembling battery and inverter systems.
• Participate in hands-on prototyping and pilot builds, helping debug issues and improve manufacturability.
• Support factory line layout and workstation design to improve flow, ergonomics, and efficiency.
• Help document assembly processes, write work instructions, and support technician training.
• Analyze data from prototype and production runs to identify bottlenecks and opportunities for process improvement.
• Contribute to design reviews with a focus on manufacturability and scalability.

What You’ll Bring

• Current junior or senior in an undergraduate program, or a graduate student, in Mechanical Engineering, Manufacturing Engineering, or a related technical field.
• Strong understanding of mechanical or manufacturing engineering fundamentals.
• Passion for hands-on problem solving and building processes that scale.
• Familiarity with CAD tools (e.g., SolidWorks, CATIA, or AutoCAD) is a plus.
• Exposure to manufacturing processes, automation, or robotics is a plus.
• Curious, self-motivated, and eager to tackle hard problems with real-world impact.

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.
