Power Electronics Controls Engineer


SpanIO, based in San Francisco, is developing products to reduce the cost and complexity of adopting distributed energy systems. We are a group of engineers with a passion for building products that can deliver a positive impact on the environment while enhancing consumer experience. We believe that developing intelligent hardware and software that provides visibility and control at the edge-of-grid will be transformational to the energy sector.

We are backed by domain experts in energy, software, hardware, and consumer finance. We are leveraging our teams collective experience in power generation, energy conversion, controls, and system integration to develop our core product focused on enabling the rapid adoption of renewable energy.


As our first controls engineer, you’ll take ownership over the control algorithms and state machines for our entire system. We’ll look to you to build models, design algorithms and system behavior, and both guide and contribute to our firmware development effort.

Your work will include

  • Design crucial safety and power quality algorithms for ensuring system up-time and reliability

  • Define logic for software defined circuit branch controls with real-time user input

  • Develop the sequence of operations for reliable off-grid transition and power flow management

  • Design energy metering measurement scheme and controls

  • Implement metering and controls algorithms into our codebase


We’re looking for someone who has:

  • Extensive modeling experience in MATLAB, Simulink

  • Experience contributing to C/C++ firmware codebases

  • Deep understanding of grid codes and regulations around grid-interactive power systems

  • Experience designing control schemes for high-efficiency, multi-phase inverters and/or DC/DC converters

  • Understanding of microgrid dynamics and microgrid control strategies
