• Lead daily scrap review activities, evaluate customer returns, identify causes, and initiate corrective actions when needed.
• Track samples and associated documentation through the foundry and finishing process, including process instructions and production records.
• Create, update, and audit procedures, SOPs, work instructions, BOMs, and related process documentation.
• Support new and existing sample activity and coordinate quality documentation, including PPAP or revision-related requirements as applicable.
• Oversee foundry lab operations and serve as backup to the Lab Technician, helping ensure required testing is completed accurately and on time.
• Participate in continuous improvement initiatives and partner with production and plant leadership to strengthen quality performance.
• Provide day-to-day direction and support to the Foundry Lab Technician.

What You'll Bring

Qualified candidates will possess:

• High school diploma required.
• Approximately 5-7 years of related quality experience.
• Foundry or metallurgy industry experience required; iron casting experience strongly preferred.
• Experience with process control and production quality in a manufacturing environment.
• Experience creating, modifying, or auditing SOPs, work instructions, process instructions, and BOMs.
• Experience with ERP or manufacturing systems; Odyssey experience is a plus.
• Strong mathematical reasoning, computer skills, attention to detail, and technical aptitude.
• Strong communication and relationship-building skills across operators, leadership, customers, and team members.
• Ability to delegate, provide direction, and contribute ideas for process improvement; prior supervisory experience is preferred.

Why Join Mid-City Foundry?

• Family-owned iron foundry with more than 80 years of history and long-term customer relationships.
• Hands-on quality role with direct impact on production, process control, and continuous improvement.
• Opportunity to work closely with quality and plant leadership while helping shape stronger processes.
