What They Do

Eos Energy Enterprises specializes in developing innovative zinc-powered battery energy storage systems (BESS), particularly their proprietary Znyth® aqueous zinc battery technology. This technology is designed for long-duration energy storage, offering discharge durations ranging from 3 to 12 hours, which provides a viable alternative to traditional lithium-ion and lead-acid batteries. The company emphasizes safety, scalability, and efficiency, with a 20-year useful life for its products, all manufactured in the U.S. (source: stockanalysis.com). Their product lineup includes the Z3 battery module, battery management systems for remote monitoring, and comprehensive project management services, catering to utility-scale, microgrid, and commercial applications to address grid complexity and renewable energy intermittency (source: eose.com). Target markets include utilities, independent power producers, and commercial customers, with a focus on integrating renewable energy sources like solar and wind into their systems (source: mapquest.com). Eos differentiates itself through its non-flammable zinc chemistry, positioning against competitors such as ESS Inc. and Form Energy, and aims to enhance grid stability through long-duration storage solutions (source: dcfmodeling.com).

Projects & Track Record

Eos Energy Enterprises has made significant strides in the energy storage sector, with notable projects including the first commercial shipments of its Znyth® technology in 2017, marking a successful transition from research and development to market entry (source: dcfmodeling.com). A key project involved a $20 million order from EnerSmart for a 9MWh installation in El Cajon, California, aimed at enhancing grid stability and scheduled for deployment in Q4 2021 (source: eose.com). Ongoing projects include a commitment to deliver between 90MWh and 180MWh of Znyth®-powered storage across multiple locations in California, reflecting the growing demand for long-duration energy solutions (source: eose.com). The expansion of their Turtle Creek manufacturing facility is crucial for scaling production to meet these demands and support future growth (source: dcfmodeling.com). Key clients include EnerSmart, which focuses on utility-scale projects, and partnerships are being developed to enhance supply chain efficiency and installation speed (source: eose.com).

Recent Developments

In recent years, Eos Energy Enterprises secured its largest order to date, a $20 million contract from EnerSmart for energy storage solutions, underscoring the increasing demand for their technology in California (source: eose.com). The company has also aggressively expanded its manufacturing capabilities at the Turtle Creek facility, transitioning to high-volume production following its public listing in 2020 (source: dcfmodeling.com). While no specific acquisitions or mergers have been reported since the SPAC merger, the EnerSmart deal represents a significant commercial milestone for Eos, highlighting its growth trajectory in the energy storage market (source: eose.com).

Job Description

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.

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

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

Education and Experience

  • Bachelor's degree in electrical engineering required.
  • Minimum of 5 years' experience

Travel

  • Local Travel: 10-25%
  • Overnight/North America: 10-25%
