System Engineer Packaging Jobs in Texas (NOW HIRING)

Power Generation delivers integrated energy solutions that support reliable, efficient, and lower-emission operations across upstream, midstream, LNG, and industrial applications. Our technologies include natural gas treatment, power systems integration, and advanced process solutions that enable customers to optimize energy utilization and reduce environmental impact. 

The Principal Battery Energy Storage System (BESS) Integration Engineer serves as a technical authority for the evaluation, specification, integration, commissioning, and lifecycle management of battery energy storage systems supporting advanced power generation solutions.

This role provides system-level engineering leadership across BESS technology selection, electrical integration, protection, controls, communications, safety, and commissioning. Working closely with electrical, controls, civil, mechanical, procurement, construction, commissioning, safety, and operations teams, the engineer develops technical standards and specifications, evaluates vendors, and ensures BESS solutions deliver the required performance, reliability, safety, and long-term value.

The position will have particular focus on BESS integration supporting AI and hyperscale data centers, behind-the-meter generation, microgrids, and other complex power systems.

Key Responsibilities

• Lead the development of technical requirements and performance specifications for utility-scale and behind-the-meter BESS installations, including capacity, duration, dynamic response, reliability, grid-forming/grid-following operation, and black-start capability.
• Evaluate BESS technologies, system architectures, suppliers, and integrators; develop technical bid evaluations and support vendor selection and commercial negotiations.
• Define electrical integration requirements between BESS, generation assets, medium-voltage distribution systems, switchgear, transformers, microgrids, and data center loads.
• Establish protection, controls, communications, and energy-management requirements, including voltage and frequency regulation, load sharing, state-of-charge management, and emergency operating modes.
• Develop system-level operating philosophies and Theory of Operation documentation for normal, islanded, generator-support, load-transient, black-start, emergency, and maintenance conditions.
• Lead technical safety and reliability assessments, including thermal-runaway mitigation, fire protection, HAZOP, FMEA, risk assessments, and applicable code and standards compliance.
• Develop lifecycle and total-cost-of-ownership evaluations considering degradation, auxiliary power, augmentation strategies, warranties, operating costs, and end-of-life requirements.
• Develop repeatable engineering, site-layout, installation, and construction standards for BESS deployments.
• Lead or support factory acceptance testing, site acceptance testing, commissioning, energization, troubleshooting, performance validation, and turnover to operations.
• Collaborate across engineering, procurement, construction, operations, safety, and commercial teams to ensure BESS solutions meet technical, contractual, and business requirements.

Required

• Bachelor's degree in Electrical Engineering, Power Systems Engineering, Energy Systems Engineering, or a related technical discipline.
• Minimum 7 years of experience in power systems, energy storage, renewable integration, utility infrastructure, or data center power projects, including direct experience with utility-scale or industrial BESS.
• Experience integrating BESS with generation assets, medium-voltage distribution systems, microgrids, or other complex electrical systems.
• Strong knowledge of battery technologies, power conversion systems, protection and controls, power-system modeling, energy management, and grid-forming/grid-following inverter technologies.
• Experience reviewing EPC and vendor engineering packages, technical specifications, equipment designs, and system integration requirements.
• Strong systems-engineering judgment, analytical problem-solving, technical communication, and cross-functional collaboration skills.

Preferred

• Master's degree in Electrical Engineering, Power Systems, Energy Systems, or a related discipline.
• Experience supporting AI or hyperscale data center power infrastructure, behind-the-meter generation, or high-availability power systems.
• Experience with gas-engine integration, microgrids, islanded power systems, or black-start applications.
• Familiarity with IEC 61850, Modbus, DNP3, OPC UA, digital substations, or related power-system communication protocols.
• Experience with power-system simulation and analysis tools such as ETAP, PSCAD, or equivalent.

Candidates who exceed minimum qualifications may be considered for higher-level positions based on experience, capability, and business needs. Career progression includes R&D Electrical Engineer Advisor, R&D Electrical Engineer Senior Advisor and R&D Electrical Engineer Chief Advisor.
