Our company is seeking a skilled and detail-oriented Quality Engineer to join our team in Houston, TX. In this role, you will own the quality assurance, structural weld compliance, and engineering documentation processes for grid-scale battery energy storage system (BESS) containers. You will be directly responsible for establishing weld inspection protocols, ensuring compliance with U.S. welding codes, and updating AutoCAD drawings to reflect real-world manufacturing quality updates, material adjustments, and weld change-orders. This is an immediate-start position open to both Direct Hire and Contract-to-Hire candidates. Key Responsibilities Quality Documentation & AutoCAD Updates: Modify, update, and manage engineering drawings in AutoCAD to accurately reflect manufacturing quality updates, non-conformance corrections, and changes in metal materials or weld types. Welding Inspection & Compliance: Develop, implement, and oversee strict weld inspection processes to verify that all structural enclosures meet applicable United States weld quality codes and standards. Defect Material Analysis: Troubleshoot fabrication floor quality issues, managing corrections related to varying metal materials, structural integrity, and weld defects. Thermal System QA: Verify the quality, fitment, and integration standards of air-cooled or liquid-cooled HVAC systems crucial for BESS thermal management. Continuous Improvement: Audit the production floor, manage root-cause analysis for fabrication errors, and update standard operating procedures (SOPs) to prevent repeat quality escapes. Requirements Required Qualifications Experience: 5 to 7 years of quality or manufacturing engineering experience in heavy container, industrial enclosure, or BESS manufacturing. Weld Code Expertise: Deep, practical knowledge of U.S. welding codes (e.g., AWS D1.1 or similar structural welding standards) and formal weld inspection methodologies. Technical Drafting Skills: Strong proficiency updating fabrication drawings in AutoCAD based on production quality changes and engineering revisions. Availability: Must be able to start ASAP in the Houston, TX area. Preferred Qualifications Certified Welding Inspector (CWI) or equivalent quality certification. Experience updating or reviewing models and drawings using Creo. Familiarity with the integration and quality testing of liquid-cooled or air-cooled HVAC units within industrial enclosures.
