• Collaborate with sales teams on technical proposals, RFIs/RFQs/RFPs, customer presentations, and solution reviews.
• Perform system sizing, equipment selection, and application analysis for energy storage, renewable generation, and microgrid systems.
• Design and evaluate system architectures involving BESS, PCS/inverters, microgrid controllers, EMS/SCADA systems, and utility interconnections.
• Support system integration, Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), commissioning, and troubleshooting activities.
• Serve as a technical advisor to customers, EPCs, consultants, and utility stakeholders throughout the project lifecycle.
• Ensure solutions comply with customer requirements, industry standards, and utility interconnection guidelines.
• Work closely with controls, software, systems, and product engineering teams to resolve technical challenges and improve solution offerings.

Key Competencies

• Strong customer-facing and technical communication skills.
• Ability to translate customer needs into practical engineering solutions.
• Systems-thinking approach to integrating generation, storage, controls, and utility interfaces.
• Structured problem-solving and troubleshooting capability.
• Strong collaboration across sales, engineering, product management, and project teams.
• Ownership, accountability, and adaptability in a fast-paced environment.

Travel Requirement: 30 - 40% travel for customer meetings, site visits, commissioning support, and technical workshops.

Minimum Qualifications

Bachelor's degree in Electrical Engineering, Power Systems Engineering, or a related discipline.

• Experience in microgrids, energy storage, power systems, renewable energy, or distributed energy applications.
• Strong understanding of:
• Battery Energy Storage Systems (BESS)
• Distributed Energy Resources (DER)
• Power Conversion Systems (PCS) and inverter technologies
• Microgrid architecture and operation
• Utility interconnection requirement
• Electrical power systems and protection fundamentals
• Experience with microgrid controllers, EMS/SCADA systems, or plant-level controls is highly desirable.
• Ability to interpret single-line diagrams, electrical schematics, and system architecture drawings.
• Familiarity with power system modeling and analysis tools such as ETAP, MATLAB/Simulink, PSCAD, PLECS, or DIgSILENT.
• Validate control performance through:
• Software-in-the-Loop (SIL)
• Hardware-in-the-Loop (HIL)
• Factory and site acceptance testing (FAT/SAT)

Preferred Qualifications

• Advanced degree (M.S.) in Electrical Engineering or related field.
• Experience with grid-forming and grid-following inverter technologies.
• Knowledge of IEEE 1547, UL 9540/9540A, NFPA 855, NEC, and utility interconnection standards.
