Manufacturing Engineering Intern

Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time.

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.

• →

  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.

• 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.

Makers of the machines that power tomorrow. The Manufacturing Engineering team owns the interface between a proof of concept and a scalable, profitable product. Our team focuses on how a product can be built, defining the process technology and equipment solutions along the way. We are the feedback loop with the product design team to ensure designs are manufacturable both at cost and scale. The Manufacturing Engineering team owns every aspect of bringing the physical mechanisms of manufacturing a product into the factory.

Please note: Base is a startup, which means priorities shift and evolve quickly. Your role may expand or change based on the needs of the business at any given time, so the responsibilities listed may not be exhaustive.

• First Principles Thinking: Question assumptions. Principles > rules.

• Operate at Base Pace: Focus on what matters, act quickly, and learn by doing.

• Give & Get Feedback: Be direct, be humble, and maintain a growth mindset.

• Everyone’s an Owner: Follow through on commitments and own results.

• Strong Opinions, Loosely Held: Drive clarity and make calls with imperfect information.

• Committed to the Mission: Rebuilding the grid is a big challenge. We work hard because we care deeply about the impact we’re creating. We work in-person. It’s not a 9-to-5. We are all-in.

• Fun & Optimism Coexist with Grit: Collaboration and celebration coincide with the intensity of building real things.
