Company

hirify.global is localizing the battery supply chain through battery recovery, reuse, recycling, energy storage, and production of battery materials in the United States.

What you will do

• Design and optimize control algorithms for high-power battery energy storage systems, including grid-forming, grid-following, and multi-asset synchronization.
• Develop bidirectional DC/DC and AC/DC control schemes for industrial-scale energy storage, optimizing efficiency, thermal stability, and safety.
• Build high-fidelity digital twins of power stages and grid environments with PLECS and MATLAB/Simulink.
• Lead hardware-in-the-loop testing environments using Opal-RT and Typhoon to validate control firmware under transient and fault conditions.
• Implement control strategies for mixed-asset battery arrays, including recycled battery chemistries.
• Collaborate with electrical, firmware, thermal, battery, and systems engineers on the roadmap for energy storage site controllers.

Requirements

• MSc or PhD in Electrical Engineering specializing in Power Electronics Control Systems; an MSc requires 3+ years of relevant industry experience.
• Deep expertise in high-efficiency power conversion, including LLC, CLLC, DAB, Flying Capacitor, and ANPC topologies.
• Experience designing robust closed-loop controllers using Bode, Nyquist, and state-space methods.
• Experience implementing controllers on DSPs or microcontrollers and strong proficiency in C for real-time embedded systems.
• Expert-level MATLAB/Simulink and PLECS skills, plus Python for automation, scripting, and data analysis.
• Familiarity with grid-interconnection standards such as IEEE 1547 and UL 1741 is highly desirable.

Culture & Benefits

• Work in a fast-paced R&D environment focused on modernizing the energy grid and enabling circular battery systems.
• Full-time employment with compensation based on experience.
• Collaborate across electrical, firmware, thermal, battery, and systems engineering disciplines.
