About magniX:Based in the beautiful Pacific Northwest, magniX builds solutions for the electric age, applying its aerospace-grade batteries, power electronics, power distribution, electric engines, and software to mission-critical applications across data centers, energy storage, defense, mobility, space, and aerospace. Built on an 800-volt architecture, magniX technology delivers industry-leading energy density, cycle life, and safety, and magniX electric engines have powered more than 200 flights across six different airframes, where the company remains the industry leader.
As magniX extends its aerospace-grade standards into new markets, we are building a commercial organization to match, and are now ready to take our technology and products to market. Be part of a passionate team that is ushering in the electric age.
About the role: 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.
Primary 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.
