Job description

About Base
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.
About the Role
We are looking for a Hardware Integration Engineer to help design and integrate the next generation of Base Power's residential battery storage, inverter, and microgrid interconnect device (MID) systems. This role requires strong electrical engineering fundamentals and hands-on experience with complex energy storage hardware. You'll play a critical role in building safe, reliable, and scalable hardware systems that power homes and communities.
What You'll Do
  • Design and integrate battery management systems (BMS), inverters, and MID hardware for residential energy applications.
  • Develop and maintain system architecture and electrical schematics for multi-component energy systems.
  • Conduct testing, validation, and troubleshooting of integrated hardware systems.
  • Partner with software teams to ensure seamless hardware/software integration and control algorithm development.
  • Support regulatory compliance and product certification processes to meet industry standards.

What You'll Bring
  • BS/MS in Electrical Engineering (or related field) with 3+ years of hardware development experience, ideally in energy storage or power systems.
  • Core Technical Knowledge:
    • Electrical engineering fundamentals: circuit analysis, analog/digital electronics, high-voltage design.
    • Power electronics: DC-DC/DC-AC converters, inverters, switching power supplies, grid-tie systems.
    • Battery systems: Li-ion/LiFePO4 technologies, BMS design, charging algorithms, safety systems.
    • Software: embedded programming (C/C++, Python), communication protocols (CAN, Modbus).
    • Physics background in electromagnetics, thermodynamics, and measurement principles.
  • Tools & Software:
    • PCB design tools (Altium Designer, KiCad).
    • Circuit simulation tools (LTSpice, MATLAB/Simulink).
    • Test equipment operation.
    • Familiarity with UL 1741, IEEE 1547, NEC standards.

Preferred Skills
  • Professional Engineer (PE) license or ability to obtain.
  • Experience with residential energy codes and smart home integration.
  • Background in product certification and regulatory approvals.

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.
Our Values
  • 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.
Do the best work of your life at Base.
