Energy Innovations, based in San Diego, CA has pioneered the development of Highly Concentrated Photovoltaic (HCPV) systems that use concentration to substantially reduce the cost of solar energy. EI's mission is to leverage the benefits of concentrated solar to achieve economic parity with fossil fuel generated power alternatives, making EI the first choice for alternative energy.

EI's breakthrough Sunflower system uses Fresnel lenses to concentrate the sun 1,200:1 onto ultra high efficiency PV cells adapted from the satellite industry. Our module operates at twice the efficiency of traditional crystalline silicon PV panels and when coupled with our revolutionary low cost 2-axis tracker, generates 30% more energy than current generation PV panels.

EI is seeking a Software Engineer to participate in the development of our tracking control, wireless communications and status monitoring systems.

Energy Innovations is an operating company of Idealab, a prolific creator and operator of technology businesses.

The successful candidate will design, implement, test and maintain key elements of our system software as listed below.

1. Sun-tracking and power optimization algorithms
2. Closed loop sun tracking software
3. Open loop sun tracking software
4. Microcontroller-based motor control
