Energy Storage Systems Engineer (Full Stack, Cell To Field Deployment)

Role Overview We are seeking an experienced engineer to lead the design, development, and deployment of our proprietary ZincGel battery energy storage systems (BESS). The role requires end-to-end expertise – from cell-level design to integration, field deployment, and lifecycle management. The candidate will drive system architecture, identify and collaborate with subsystem providers, and ensure robust performance in both low-voltage and high-voltage applications.

Key Responsibilities

Lead the full-stack design of ESS : from pack design, enclosure, safety systems, and field deployment.

Architect both low-voltage (LV) and high-voltage (HV) battery systems for stationary applications.

Define and validate specifications for battery packs, power electronics, protection systems, and communication interfaces.

Evaluate and select subsystem providers (BMS, inverter, EMS, thermal, safety, control) ensuring interoperability and reliability.

Develop and validate models and algorithms for State of Health (SoH) and State of Charge (SoC) determination.

Lead prototyping, testing, and certification of systems to meet relevant safety and performance standards (IEC, UL, grid codes).

Collaborate with manufacturing and field teams for seamless scaling, deployment, and maintenance.

Stay updated with the latest in cell chemistries, power electronics, and ESS integration trends.

Qualifications & Skills

Bachelor’s or Master’s or PhD degree in Electrical Engineering, Power Electronics, Energy Systems, or related field.

7+ years of hands-on experience in designing and deploying ESS from cell to system level.

Proven experience working with both low-voltage ( and high-voltage (>

400V) systems.

Strong expertise in system engineering BMS / EMS integration, protection strategies, and communication protocols (CAN, Modbus, Ethernet, etc.).

Practical knowledge of inverter integration, grid interconnection requirements, and thermal management systems.

Solid grasp of battery modeling, SoC / SoH estimation methods, and performance testing.

Demonstrated ability to source and manage third-party subsystem providers.

Familiarity with safety, compliance, and certification standards for ESS.

Strong problem-solving, system-level thinking, and hands-on prototyping skills.

Preferred

Experience with renewable integration, microgrids.

Exposure to zinc-based, flow batteries, or alternative chemistries beyond Li-ion.

Track record of taking products from R&D to field deployment at scale.

Selection process

Due to large number of applications, only shortlisted candidates will be contacted for further screening test, assignment - followed by an interaction.
