Power Electronics Lead

About the Company

Peak Energy is the first American venture to advance globally proven Sodium‑Ion battery systems as the storage standard for the new era of renewable energy on a resilient grid. Sodium‑Ion is cheap, readily available, and safe, making it the leading contender in a rapidly evolving market. Our leadership team is powered by decades of expertise in scaling gigawatt‑level innovation at world‑class companies such as Tesla, Northvolt, Sun Power, Fluence, and Enovix.

We are backed by strategic investment and product partners such as TDK Ventures and Eclipse Ventures. We are a team of engineers, operators, entrepreneurs, and partners driven by a shared ambition to set the new performance standard for renewable energy and grid resilience.

We’re looking for a Power Electronics Lead to join our Energy Storage Systems (ESS) Engineering team. This person will be responsible for the architecture, design, and technical direction of our power conversion systems, shaping how energy moves within and beyond our battery systems—from cell to grid.

• Lead the design and development of high‑voltage power conversion systems within Peak’s energy storage platform, including DC/AC inverters, bidirectional DC/DC converters, and protection circuitry.
• Define and maintain system‑level electrical requirements for power stages, gate drives, control loops, safety interfaces, and EMI/EMC performance.
• Select and integrate key components (e.g., IGBTs, SiC/GaN FETs, magnetics, busbars, filters) and collaborate closely with mechanical and thermal engineers to support packaging and cooling.
• Own system‑level testing and validation—both in‑lab and in‑field—including HV safety, transient behavior, thermal performance, and fault response.
• Interface with firmware, controls, and systems teams to ensure robust hardware/software integration and safe system operation.
• Support regulatory certification and compliance activities (IEEE 2800, UL 1741, IEEE 1547, IEC 62109).
• Act as a technical leader and mentor across the ESS team—setting high standards, reviewing designs, and driving toward first‑principles, scalable solutions.

• 8+ years of experience designing power conversion systems for energy storage, renewables, automotive, or industrial applications.
• Expertise in high‑power and high‑voltage (100 kW+) converters and inverters—particularly in topologies, switching devices, protection, and control strategies.
• Strong working knowledge of high‑voltage system design, insulation coordination, and thermal management.
• Skilled in simulation and design tools (SPICE, PLECS, MATLAB/Simulink, Altium) and comfortable with lab testing in HV environments.
• Deep understanding of compliance and grid standards including IEEE 2800, UL 1741, IEEE 1547, and IEC safety requirements.
• Excellent communicator and collaborator, capable of aligning with cross‑functional teams and driving high‑quality decisions.
• Bachelor’s, Master’s, or PhD in Electrical Engineering or a related field.

• Experience with silicon carbide (SiC) module integration and design for manufacturability.
• Exposure to full ESS architecture and system integration challenges (e.g., BMS, EMS, HVDC interfacing).
• Prior work in startups or early‑stage product environments.

• Speed Through Focus:
  Prioritize what matters most and execute quickly without distractions.
• Mission Over Self:
  Put the company’s mission and team success ahead of individual interests.
• Face the Brutal Truth:
  Embrace honesty, even when it’s uncomfortable, to make informed decisions.
• Be a Good Person:
  Treat everyone with respect and integrity, fostering a positive and ethical work environment.

The salary range for this role is $185,000‑$250,000, varying by location, experience, and skills. Our benefits include flexible PTO, comprehensive medical, dental, and vision coverage, a strong 401(k) plan, and equity opportunities.
