Sr. Electrical Engineer - Digital Power and LED Drivers
Ecosense is a rapidly growing technology company based in Los Angeles. Our purpose is to invent, inspire and transform how we experience light. Our strategy is audacious, and our expectations are high. We are pioneering in the areas of color science, photometry and mixed reality. Using the sun and the moon as inspiration, we are using our inventions to enhance our industry’s understanding of light and materially transform expectations for artificial light.
We have been fortunate to light some of the most coveted spaces on earth and to be recognized by the likes of Red Dot for innovation and design, as well as Inc 500 and Deloitte for consistently making their fastest growing companies lists.
Ecosense hires curious, collaborative, autonomous and smart people who also happen to be very nice. We have a passion for tackling the unknown, solving hard problems, and answering questions that haven’t been explored.
Primary Role and Responsibility:
The Sr. Electrical Engineer (Digital Power and LED Drivers) will come with substantial experience in the design and development of highly-efficient power supply and LED driver designs. You will be a part of the process from concept investigation and design analysis to successful production execution. Using analytical and problem-solving skills the Electrical Engineer will help guide decision making in the organization.
The candidate must have domain expertise with designing, modeling, trouble shooting, and verifying stability of digital power control loops. This individual must have deep expertise of offline conversion topologies including Flyback, Buck, PFC, resonant converters, LLC and analog/digital controls loops.
Candidate must be intimately familiar with power supply safety and environmental certifications, offline controllers, components, magnetic design, power supply layout and state-of the art techniques for efficiency optimizations including no load/light load efficiency techniques.
The Sr. Electrical Engineer will help in architecture investigation with the power architect and help determine the best design option for power metric performance optimization including but not limited to efficiency, power density, cost and scalability.
