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
Controls/Firmware Engineer develops the architecture that ties the battery management system, power converter, and datacenter rack power management together. They will design charge/discharge control algorithms, fault handling logic, and the communication layer connecting the power system to datacenter IT infrastructure.
Primary Responsibilities:- Design and implement control algorithms for battery charge/discharge management, converter operation, and mode transitions (grid-tied, UPS/backup, islanded).
- Develop fault detection, protection, and graceful-degradation logic across the battery, converter, and rack interface.
- Implement communication protocols to interface with datacenter power and IT management systems (e.g., Modbus, CANbus, PMBus, Redfish).
- Collaborate with the Power Electronics and Battery Systems Engineers to define control interfaces and timing requirements.
- Support hardware-in-the-loop and system-level test activities.
Required Qualifications:- Bachelors' Electrical Engineering, Computer Engineering, or related field
- 5+ years in embedded controls or firmware for power systems.
- Experience with real-time control of power converters or battery management systems.
- Proficiency in embedded C/C++ and familiarity with common industrial communication protocols (CANbus, Modbus, or similar).
Preferred Qualifications:- Experience with datacenter power/IT protocols (PMBus, Redfish, SNMP).
- Background in aerospace or automotive controls, adaptable to stationary/industrial applications.
- Experience with functional safety practices (e.g., IEC 61508, ISO 26262) as applied to power systems.
Location: Applicants must be willing and able to commute to magniX's location in
Everett, Washington.
