About The Position

Eos Energy Enterprises, Inc. is accelerating the shift to American energy independence with positively ingenious solutions that transform how the world stores power. Our breakthrough Znyth™ aqueous zinc battery was designed to overcome the limitations of conventional lithium-ion technology. It is safe, scalable, efficient, sustainable, manufactured in the U.S., and the core of our innovative systems that today provides utility, industrial, and commercial customers with a proven, reliable energy storage alternative for 3 to 12-hour applications. Eos was founded in 2008 and is headquartered in Edison, New Jersey. For more information about Eos (NASDAQ: EOSE), visit eose.com. The Control Systems Design Engineer helps develop the control strategies that manage battery behavior, grid interactions, and site‑level automation. This role will work closely with the engineering teams to integrate BMS, PCS, and EMS controls into a cohesive platform that supports reliable energy delivery.

Requirements

• Strong understanding of battery energy storage systems, including BMS, PCS, EMS, and site‑level controls.
• Proficiency with PLC programming (e.g., Allen‑Bradley, Siemens), SCADA platforms, and industrial communication protocols (Modbus, CAN, IEC 61850).
• Knowledge of power systems, including inverters, transformers, switchgear, and grid interconnection requirements.
• Experience with control theory, system dynamics, and real‑time control implementation.
• Ability to interpret single‑line diagrams, control schematics, and electrical drawings.
• Strong troubleshooting skills for both hardware and software issues in complex energy systems.
• Bachelor's degree in electrical engineering required.
• Minimum of 5 years' experience

Nice To Haves

• Experience with energy storage, renewable energy, or power electronics preferred.
• Knowledge of relevant standards (UL, IEEE, NFPA) and utility interconnection requirements.

Responsibilities

• Design and develop control system architectures for BESS, including battery management system (BMS) integration, energy management system (EMS) logic, and power conversion system (PCS) controls
• Create control algorithms for charge/discharge cycles, state‑of‑charge (SOC) balancing, and grid support functions (e.g., frequency regulation, voltage support).
• Develop PLC, SCADA, and HMI logic tailored to energy storage applications
• Model and simulate system behavior using tools such as MATLAB/Simulink to validate control strategies under various grid and environmental conditions.
• Collaborate with electronics engineering, software engineering, and manufacturing teams to ensure seamless integration of control hardware, sensors, and communication networks.
• Support commissioning and field deployment, including troubleshooting control logic, tuning system parameters, and validating performance on live systems.
• Ensure that designs comply with safety standards such as UL 9540, UL 1741, NFPA 855, and IEEE grid interconnection requirements.
• Develop technical documentation, including control narratives, functional design specifications, test procedures, and system architecture diagrams.
• Continuously improve system performance by implementing advanced control strategies, predictive analytics, and optimization techniques
