Overview 

The Site ReadinessTechnician plays a critical role in ensuring all delivered and installed equipment meets the project Quality Plan, industry standards, and manufacturer specifications. This role performs detailed receiving inspections, validates construction quality after mechanical completion, and ensures Battery Energy Storage System (BESS) equipment is ready for commissioning and energization. 

The ideal candidate has strong experience in utility-scale power systems—such as BESS, solar, thermal/gas turbine, or other power plant environments—and thrives in a fast-paced, travel-heavy field role. 

Key Responsibilities 

Equipment Receiving & Quality Inspections

Mechanical Completion Verification 

• Inspect equipment installations after mechanical completion to verify workmanship quality, adherence to codes/standards, and compliance with OEM requirements.

• Conduct detailed inspections on wiring terminations, cable routing, torque requirements, labeling, grounding, conduits, and enclosure integrity.

• Review and verify that installation meets NEC, IEEE, UL 9540/9540A, relevant utility standards, and project-specific QA/QC criteria. 
   

Documentation & Reporting 

• Maintain thorough inspection reports, punch lists, redlines, and photographic documentation.

• Track and verify corrective actions, ensuring issues are closed prior to energization or commissioning handoff.

• Support QA Manager in maintaining project-level Quality Plans and documentation control. 
   

Cross-Functional Collaboration 

• Work with construction teams, commissioning engineers, EPC partners, and OEM representatives to resolve field quality issues.

• Communicate findings clearly and professionally across disciplines, escalating issues when required.

• Support readiness reviews, quality walkdowns, and pre-energization verification activities. 
   

Required Qualifications 

• 3+ years of experience in one or more of the following:

• Power plants (thermal, gas turbine, peaker, etc.)

• Utility-scale solar

• Battery Energy Storage Systems

• High-voltage electrical or industrial environments 

• Data Centers 

• Strong ability to read and interpret electrical/mechanical drawings, one-lines, installation manuals, and QA/QC documentation.

• Experience performing field inspections, equipment verification, or construction quality control.

• Willing and able to travel over 80% to project sites nationwide.

• Understanding of codes and standards such as NEC, NFPA, IEEE, UL, ISO/IEC, and utility requirements. 
   

Preferred Qualifications

• Prior experience in QA/QC, commissioning, or field service roles.

• Familiarity with BESS architectures, inverters, transformers, MV equipment, and SCADA/telecom cabinets.

• Certifications such as NETA, AWS CWI, ISO 9001 auditor, or OSHA 30. 
   

Soft Skills 

• Strong attention to detail and a “zero-defect” mindset.

• Excellent communication and documentation habits.

• Ability to work independently in remote field environments.

• Professional, solution-driven approach to problem solving
