Power Electronics Engineer

MAGNIX USA INC • Everett, WA

2d • $120,000 - $165,000 • Onsite

About The Position

magniX is building a small, cross-functional team to develop a new 800V battery-based power supply and backup system for datacenter compute racks, drawing on the company's deep bench of electric propulsion battery and power electronics expertise. The Power Electronics Engineer will lead the design of a bidirectional power converter and charger, operating at the core of the system's power path between the 800V battery pack, the grid or facility AC input, and the datacenter rack DC bus.

Requirements

• Bachelor's in electrical engineering or related field
• 7+ years in power electronics design.
• Demonstrated experience taking a high-voltage (600V+) power converter from concept through production, including topology selection and control implementation.
• Experience with bidirectional converter topologies (charger/inverter combined function).
• Familiarity with SiC or GaN power semiconductor devices and associated thermal/EMI design considerations.

Nice To Haves

• Experience in EV traction inverter design (particularly 800V platforms) or grid-tied/UPS inverter design for stationary storage.
• Exposure to datacenter power standards or utility interconnection requirements.
• Experience standing up a new power electronics product line from a clean-sheet or early-concept stage.

Responsibilities

• Lead the design of a new bidirectional AC/DC and DC/DC power converter suitable for stationary, continuous-duty datacenter operation.
• Define power stage architecture, semiconductor selection (SiC/GaN), and switching strategy for 800V-class operation at datacenter power levels.
• Develop control loops for battery charging, rack-bus voltage regulation, and grid-interactive or UPS-style operating modes.
• Own the electrical interface between the converter, the battery management system, and rack-level power distribution.
• Support compliance activities against relevant standards (e.g., UL 1741, IEEE 1547, UL 9540) in partnership with the Systems Engineer.
• Serve as the technical lead for the team's power electronics workstream, including design reviews and supplier/component sourcing decisions.

Benefits

• 100% company-paid premiums for medical, dental, and vision insurance (for employees & dependents).
• 4 weeks paid vacation + 1-week annual end-of-year shutdown, sick time, and 11 paid holidays.
• 401K retirement plan with industry leading 9.5% company contribution.
• Company paid Life insurance, AD&D, Short-Term and Long-Term disability insurance
• Catered lunches and quarterly company fun-day events!
