Power Electronics Test Engineer

Description

Full Job Description

Ambrosia Energy is on a mission to make solar + battery systems the fastest-to-deploy and most cost-effective energy source in the US and beyond. As global energy demand surges—driven by the rapid rise of data centers, electric vehicles, and future in-home robotics—the world stands at a critical energy inflection point. To meet this challenge, we need innovative, scalable power sources. Our engineering-led team, with expertise in designing and deploying satellite constellations (Swarm, Starlink Mobile), is now focused on energy on Earth. We're developing affordable, clean energy solutions with new battery storage systems. United by strong team camaraderie, we prioritize speed, rapid iteration, vertical integration, and a test-like-you-fly approach. We're committed to making an impact on the future of energy.

We are designing and developing a distributed battery storage system to pair with solar panels that are quick and easy to install. The system is simple, robust, reliable, and easy to manufacture at scale. The system will include highly efficient DC-DC conversion, solar MPPT, power distribution, no moving parts, and efficient cable management to make everything plug and play in the field.

We are seeking a skilled Power Electronics Test Engineer to test, debug, and validate the DC-DC, AC-DC, and bidirectional power converters used in our distributed battery storage system paired with solar generation.

The ideal candidate will work closely with power electronics design, systems, and software engineers to develop high-performance power conversion and scalable product.

Responsibilities

• Design, execute, and document comprehensive verification and validation test plans for distributed battery storage systems, DC-DC converters, AC-DC stages, and solar MPPT power hardware.

• Good understanding of power electronics conversion and control.

• Review schematics and PCB layouts to assess testability.

• Good root-cause analysis on hardware bugs, power component failures, and control anomalies during rapid prototyping and test cycles.

• Utilize oscilloscopes, logic analyzers, power analyzers, electronic loads, differential probes, and programmable power supplies to safely perform high-power testing.

• Able to develop functional test benches and automated verification tests for power electronics conversion systems.

• Good technical writing and communication skills, with the ability to convey complex concepts clearly.

Qualifications

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

• 1+ years of experience in power electronics development and testing.

• Proficient understanding of power electronics fundamentals.

Preferred Skills or Experience

• Minimum of 3 years of experience in power electronics converter development.

• Knowledge of industrial environmental reliability standards.

• Hands-on experience debugging and validating embedded and electrical systems using oscilloscopes, logic analyzers, debuggers, and similar tools.
