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

Opportunity

e-Zinc is searching for an experienced and talented Software Engineer – Battery Systems to join the technology team to develop the software on industrial and embedded controllers to control and optimize the operation of our proprietary zinc-air battery systems.

Please note this is a 3 months contract with the option to extend as per business needs.

Position Scope and Responsibilities

• Design, develop, and test embedded firmware that controls the operation of zinc-air battery systems (charge/discharge cycles, safety mechanisms, diagnostics, and more)
• Write well-documented code for PLCs (e.g. Phoenix Contact PLCNext) and microcontrollers (e.g., STM32, TI MSP430, or similar).
• Implement control flows, fault detection and response, thermal management, and battery algorithms.
• Integrate sensors, actuators, and power electronics through analog, digital, and other communications interfaces.
• Contribute to system-level architecture decisions and participate in design reviews.
• Collaborate with electrical and battery teams to translate system requirements into reliable code.
• Analyze system logs, perform debugging, and propose firmware improvements based on collected data.
• Support prototype builds and field deployments by ensuring stable software integration.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Software Engineering, or related field.
• 5+ years of experience in software development.
• PLC programming experience using ladder logic and structured text, (e.g. Phoenix Contact PLCNext).
• Experience in structuring and writing embedded programs for microcontrollers using C/C++.
• Experience implementing various industrial communications protocols (CAN, CAN FD, CAN ISO-TP PROFINET, MODBUS TCP) on PLC hardware.
• Comfortable reading schematics, datasheets, hardware manuals.
• Documentation: UML, writing software documentation, Doxygen, version control (git).
• Experience working on battery management systems (BMS), energy storage, power electronics, or embedded control systems is an asset.
• Comfortable using equipment such as multimeters, oscilloscopes, or logic analyzers to debug hardware interfaces.
• Understanding of control systems (PID, fuzzy logic, etc.) and control system logic, and data acquisition.
• Strong hands-on, problem-solving skills, and attention to detail.

Who You Are

• Motivated self-starter who thrives in a fast-paced, emerging growth environment
