Bachelor's degree in Electrical, Mechanical, Industrial Engineering, Quality Systems, or a related technical field preferred.
5-10 years of quality engineering experience, ideally in energy systems, heavy equipment, utility infrastructure, or renewable energy projects, with direct experience in BESS, inverters, or related high-voltage electrical systems.
Strong technical understanding of BESS equipment, manufacturing processes, testing procedures, and relevant codes/standards (IEEE 1547, UL 9540/9540A, IEC, ISO 9001).
Proficiency in data analysis, root cause analysis tools (8D, FMEA, etc.), and quality management software.
Excellent communication, problem-solving, analytical, and leadership skills.
Ability to work independently and manage multiple tasks.

Nice To Haves

Certified Quality Engineer (CQE) or ISO 9001 Lead Auditor certification preferred.
Willingness to travel to supplier and project sites as required (up to 40%)
Familiarity with ERP/MES/QMS software for tracking supplier performance and quality metrics
Knowledge of BESS technologies and components, including lithium-ion batteries, thermal management, and power electronics, is highly desirable

Responsibilities

Plan and conduct audits and assessments of potential and existing suppliers and their manufacturing facilities to ensure compliance with quality standards like ISO 9001 and specific BESS industry frameworks (e.g., UL 9540/9540A, IEC standards).
Develop and implement supplier quality management plans, quality control plans, and programs for incoming materials and components.
Collaborate with suppliers and internal cross-functional teams (engineering, procurement, production) to identify, log, track, and resolve non-conformances (NCRs) and quality issues. Drive timely root cause analysis (RCA) and implement effective corrective and preventive actions (CAPA) with vendors.
Maintain complete and traceable quality records, inspection reports, and closeout documentation. Manage the supplier database, including performance records and certifications.
Participate in and oversee Factory Acceptance Tests (FAT), In-Process Monitoring (IPM), and Pre-Shipment Inspections (PSI) for key BESS components (modules/packs, racking, containerized systems, inverters, switchgear).
Monitor and report on supplier quality performance using key performance indicators (KPIs) and data analysis to identify trends and drive continuous improvement initiatives. Educate and facilitate the use of Lean Manufacturing and Six Sigma tools with suppliers where needed.
Ensure suppliers adhere to all applicable local and international regulatory, safety (e.g., fire safety), and compliance requirements.
Work with the engineering and supply chain teams to support new product launches, qualify new parts, and ensure that quality is "engineered" into the product design from the concept phase.
Act as the primary liaison between internal teams and external suppliers, providing technical guidance on quality-related matters and helping to define clear responsibilities.
