Senior Staff Power Electronics Engineer
We are seeking a Senior Staff Power Systems Architect to be a technical leader on power systems architecture and power electronics design for Redwood Material's skunkworks battery product. In this role, you will define system-level power architectures for our deployments, including DC and AC coupled topologies, grid interface strategies, and system fault protection schemes. In addition, you will be a key member on a team that designs and optimizes the power electronics (AC/DC and DC/DC) converters that turn these architectures into reality. Your work will include architecture definition; influencing make vs buy decisions, power electronics simulation, design and validation testing; control algorithm development and requirements definition. You will closely collaborate with firmware engineers, mechanical engineers, compliance engineers, and our in-house EPC team.
Responsibilities will include:
- Deliver multiple power converters to internal/external customers, covering from 2KW to 20MW as a team.
- Work on AC/DC and DC/DC power conversion systems as a team.
- Design the control loop of the AC/DC and DC/DC power conversion systems.
- Design the analog/digital/mixed-signal circuits on PCBA for sensing and control.
- Design magnetic components like inductors, transformers, and EMI filters.
- Lead the development of control and power conversion PCBAs.
- Work with the mechanical team to design the thermal management system.
- Lead the validation of the electro-mechanical power conversion system.
Desired Qualifications:
- Minimum 3 years of power conversion industry experience after Ph.D. degree or 6 years after an MS degree in Electrical Engineering.
- Excellent skill in circuit simulation software like SPICE, LTSpice, or PSIM.
- Excellent in system analysis software like MATLAB, Python, or Mathcad.
- Excellent debugging skills in the power conversion circuit.
- Familiar with higher than 100V DC conversion systems (Resonant DC system is a plus)
- Familiar with higher than 100V AC systems (PFC system is a plus)
- Excellent laboratory proficiency with an oscilloscope, voltage/current probes, power analyzer, and LCR meter.
- Familiarity with writing control loops in C/C++ in the bare-metal or RTOS.
