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

What you will do

• Design high-voltage, high-power converters for utility-scale battery energy storage systems and industrial infrastructure.
• Evaluate converter topologies, power-stage components, MOSFETs, gate drivers, magnetic components, EMI filters, and thermal solutions.
• Architect low-voltage subsystems covering auxiliary power, sensing, hardware protection, and high-voltage PCB/PCBA layout.
• Define system requirements, test specifications, verification methods, and mass-production tester requirements.
• Collaborate with mechanical, firmware, controls, systems, compliance, supply chain, manufacturing, and reliability teams.
• Support product certification, component qualification, dual sourcing, reliability analysis, and hardware iterations.

Requirements

• MS or PhD in Electrical Engineering with a focus on power electronics.
• 3–5 years of experience in electrical engineering, power conversion, or energy storage products.
• Hands-on experience designing hardware up to 1.5kVdc and 480Vac, including power semiconductors, gate drives, protection circuits, and AC/DC or DC/DC topologies.
• Experience with circuit, FEA, and CAD tools such as Simulink, LTspice, Ansys Maxwell/Q3D, and Altium Designer.
• Ability to design high-power, noise-sensitive PCBs, use laboratory equipment, and perform rapid hardware prototyping and verification.
• Knowledge of control theory and embedded systems, strong analytical skills, and experience collaborating with suppliers and cross-functional teams.

Culture & Benefits

• Full-time employment with compensation commensurate with experience.
• Work on high-efficiency, high-reliability, and low-cost energy storage products using repurposed batteries.
• Cross-functional engineering environment spanning product design, manufacturing, supply chain, compliance, and reliability.
