About the job

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.
  • Education: Bachelor of Science in Mechanical Engineering
  • 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.
