Quantum Electrical Engineer Jobs in California (NOW HIRING)

Pronoia Energy is a pioneering deep tech startup at the forefront of quantum energy storage innovation. As a lean, mission-driven team, we thrive on rapid prototyping, cross-disciplinary collaboration and solving complex engineering challenges to turn quantum physics into practical, scalable products. Our current focus is on developing our groundbreaking room-temperature macroscopic quantum energy storage technology that promises orders of magnitude greater energy density, faster charging, and higher power delivery as well as being cheaper and safer compared to existing battery technology. This represents a paradigm shift in energy storage with applications spanning consumer electronics, electric vehicles, renewable grids, and beyond.

To meet our ambitious goals we are hiring an Electrical Engineer to design the circuitry that turns our novel quantum energy material into a usable device. This is a hands‑on role in a high‑stakes, high‑reward startup environment where your work will directly shape the future of energy. In this role you will design and optimize the power electronics, charging and discharging circuits, sensing systems, and battery‑management electronics that sit around our core energy storage material. Because we are pursuing radically fast charging and high energy density, you are the person who has to actually handle the currents, voltages, and heat those ambitions imply, and make them safe and reliable. You will work side by side with our Principal Electrical Engineer and with cross‑functional teams in materials, cell, and physics, in a fast prototyping loop that turns unknowns into working hardware. This role is onsite in Torrance, California.

• Design and build power‑electronics circuits for charging, discharging, and power conversion around our quantum energy storage material.


• Develop the battery management system, in hardware and supporting software, that keeps cells safe, balanced, and within their limits.


• Build the sensing and measurement instrumentation that characterizes cell behavior on the bench and in test rigs.


• Own thermal management at the circuit level, treating fast charging as fundamentally a heat problem.


• Collaborate with the cell, embedded, and science teams to refine specifications and iterate toward each functional prototype.


• Contribute to troubleshooting, root‑cause analysis, and intellectual property development for novel circuit architectures.

• 3+ years of experience in electrical engineering, with demonstrated power‑electronics or battery‑management design that shipped in real hardware, not only simulation.


• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, or a related field.


• Strong expertise in analog and digital circuit design and power electronics for high‑voltage or high‑current applications.


• Fluency in thermal management, with the instinct that fast charging means heat first.


• Hands‑on experience with high‑precision measurement instruments such as oscilloscopes, spectrum analyzers, and precision power supplies.


• Comfort working in a lab around live, energetic cells, and a builder's temperament suited to a small, fast‑moving team.

• Experience in EV, aerospace, or battery‑pack power systems.


• Experience designing for high charge rates and high current density.


• Programming and automation skills (Python, C++) for test‑bench operation and data acquisition.


• Prior work in deep tech R&D alongside interdisciplinary teams in physics or materials science.

• Chance to solve one of the world's biggest engineering challenges and pioneer quantum energy storage.


• Competitive salary, equity in a transformative startup, and performance‑based incentives.


• Access to cutting‑edge labs, tools, and resources in a flexible, collaborative work environment.


• Comprehensive benefits: health insurance, unlimited PTO, professional development stipend, and relocation assistance if needed.


• A culture of innovation where your work will accelerate our path to market impact.
