​TGRC has partnered with a leading multinational conglomerate specialising in engineering, procurement, and construction (EPC), with a strong presence across infrastructure, energy, power, and heavy engineering, delivering large-scale, complex projects globally.

Job Summary:

The BESS Lead Engineer will be responsible for the technical leadership, engineering design, and delivery of Battery Energy Storage System (BESS) projects across utility-scale and hybrid renewable energy developments. The role involves leading system design, performing technical studies, coordinating multidisciplinary teams, and ensuring compliance with technical, safety, and quality standards while delivering cost-optimised and reliable energy storage solutions.

Key Responsibilities:

• Lead the engineering design and delivery of BESS projects, covering battery chemistry, duty cycling, performance metrics (round-trip efficiency, cycle life), safety, and inverter systems.

• Design and optimise BESS solutions for efficiency, reliability, and lifecycle performance.

• Perform and review system studies where required, including integration with MV/HV substations.

• Develop and review control logics, simulations, and performance models using tools such as MATLAB/Simulink, ETAP, and HOMER.

• Design battery systems, inverters, DC/DC converters, and hybrid renewable systems (Solar PV, Wind, BESS).

• Review panel architecture, thermal management, ventilation, and temperature rise calculations.

• Provide technical leadership on inverter operating modes (VAR, PF, grid-support functions, etc.).

• Conduct root cause analysis and act as a solution provider for technical challenges.

• Drive value engineering initiatives and translate concepts into cost-optimised, high-performance designs.

• Prepare and review technical specifications, including tender documentation and bid evaluations.

• Conduct engineering reviews, quality checks, and approvals of drawings, reports, and deliverables.

• Support installation and commissioning activities during the construction phase as required.

• Prepare FAT specifications, test plans, and review and interpret test results.

• Ensure full compliance with quality, H&S, and Design Management procedures.

• Coordinate daily with internal design teams (civil, instrumentation, CAD) and external stakeholders.

• Manage inputs from other departments and third parties, including geotechnical, environmental, and transport teams.

• Ensure timely delivery of all design outputs in line with client requirements and technical specifications.

• Act as a technical point of contact with vendors and clients throughout the design lifecycle.

Key Requirements:

• Bachelor’s degree in Electrical Engineering or a related discipline.

• 8–12 years of experience in BESS, energy storage, or renewable energy project engineering.

• Proven experience delivering energy storage projects within an engineering or consulting environment.

• Strong knowledge of battery technologies, inverter systems, hybrid energy systems, and grid integration.

• Hands-on experience with MATLAB/Simulink, ETAP, and related simulation tools.

• Solid understanding of control logic development, system modelling, and performance analysis.

• Experience with MV/HV substation integration and system protection philosophies.

• Strong analytical, problem-solving, and stakeholder coordination skills.
