Application Engineer - Battery Energy Storage System

Job Title: Application Engineer

Location:Toronto GTA/ Hybrid

Role Type:Contract- 12 months, (New Opening)

e-Zinc is an energy storage venture based in Toronto with a breakthrough technology poised to disrupt the market. As the global energy grid moves to higher levels of penetration of renewable energy, there is a surging need for affordable, flexible, long‑duration energy storage. e-Zinc is uniquely positioned to meet this demand as the first company in the world to “metalize” electricity.

Backed by over CAD $80 million in funding from leading global strategic and financial investors - such as Toyota Ventures, Mitsubishi Heavy Industries, Eni, Evok Innovations, and BDC - e-Zinc has garnered international recognition for its proprietary technology and visionary roadmap. Highlights include:

• Named to the Global Cleantech 100 for four consecutive years (2022–2025)
• $1M Grand Prize winner of the Impact Canada Charging the Future Challenge
• Awarded a $1.6M grant from Breakthrough Energy Solutions Canada
• Secured over $12M in funding across three projects from Sustainable Development Technology Canada (SDTC)
• Recipient of a USD $1.3M grant from the California Energy Commission

As e-Zinc moves toward commercialisation, e-Zinc is expanding its team to bring our transformative technology to market and support the future of renewable energy.

Reporting to the Chief Commercial Officer (CCO), the Battery Energy Storage System (BESS) Application Engineer is responsible for conducting techno‑economic modelling of various use cases and customer installations globally. Models will consider the load and generation profiles, electricity and capital equipment and related installation costs of the entire system at candidate sites. The Application Engineer serves as the customer's technical representative to the CCO and leads key business projects.

The successful candidate is fluent in all technical aspects of battery sizing, and power flows in and out of the battery and is a valued technical resource to advise on product specifications and work packages.

• Analyses various end‑use (loads and generation at customer projects, both utility scale and BTM) to develop power and energy models to size BESS systems and predict energy throughput through the BESS. Customer
• Develop techno‑economic models that comprehend energy input costs, charge and discharge times, efficiency losses, storage times, and resulting revenue.
• Model Active/Reactive Power, voltage, and frequency deviation resulting from varying load, generation and battery manoeuvring.
• Evaluate costs, system architectures, BOP, and operational requirements for various customer use cases.
• Research and recommend AC equipment, software, and partners for various field installations.
• Support engineering cost estimations and total cost of ownership of the system to the customer.
• Monitor and report on the performance of e-Zinc field pilot installations. Make recommendations for altered charge control and dispatch strategies and other improvements to the design of future systems.
• Work with the BMS firmware team to develop controls that enable controls that follow optimal charge control/dispatch strategy.
• Conduct Failure Modes and Effects Analysis (FMEA) on PCS, Controls and overall, BESS for the pilot installations.
• Work with the Engineering team to author and maintain engineering documents, setting project requirements.
• Support the team during commissioning, operations, and service of e-Zinc BESS installations.

• Minimum 3-5 years of experience in the Battery Energy Storage or Electric Vehicle (EV) charger or renewable power industry, especially on project design with strong working knowledge of BESS installation requirements and economic incentives in California, New York State, and other leading Energy Storage markets.
• Minimum undergraduate degree in related engineering field.
• Industry experience with Microgrid control, Demand Management, Behind‑The‑Meter storage, Electric Vehicle Charging, Solar and Wind power generation and related Power flow and Energy modelling.
• Wide range of interest and knowledge base in multiple…
