Manufacturing Engineer IV - Coil Production na AAON Inc

Description

Job Summary: This position is responsible for designing, developing, and optimizing manufacturing processes specific to the production of various types of coils in an HVAC setting. This role ensures efficient, cost-effective, and high-quality coil manufacturing by improving process capability, ensuring manufacturability of coil designs, and supporting production teams with technical expertise.

Essential Responsibilities: Manufacturing Engineering support of all products and processes.

• Provide manufacturing engineering support for HVAC coil production across all product lines.
• Develop, review, and improve workflow design, coil brazing processes, tube expansion, fin stamping, leak testing, and assembly procedures.
• Implement design-for-manufacturability principles with a focus on coil geometry, material compatibility (copper, aluminum, steel), and coil configuration.
• Lead process improvements in brazing, automated fin/tube insertion, coil bending, and leak testing operations.
• Establish, document, and maintain standard operating procedures (SOPs), work instructions, and quality control procedures tailored to coil production.
• Manage cross-functional project teams for capacity expansion projects (new fin press lines, brazing automation, leak-test stations).
• Design and improve factory layout to optimize coil material flow, brazing cell efficiency, and ergonomics.
• Collaborate with design engineering to improve coil designs for manufacturability, reliability, and cost reduction.
• Evaluate and recommend new equipment and tooling for fin presses, tube expanders, brazing stations, coil testers, and automated handling systems.
• Provide technical support to production teams for troubleshooting coil-related defects such as fin damage, tube leaks, and brazing quality issues.
• Drive continuous improvement initiatives using Lean Manufacturing and Six Sigma methodologies to reduce scrap, improve throughput, and ensure safety.
• Train operators and technicians on new processes, tools, and equipment related to coil manufacturing.
• Ensure lessons learned from coil manufacturing challenges are documented and integrated into future process designs.
• Serve as a subject matter expert for coil production processes, including brazing, refrigerant charging, coil coating, and corrosion prevention methods.
• Mentor junior engineers and technicians to build coil manufacturing expertise within the organization.

Qualifications

Requirements:

Essential:

• Must have 6+ years’ experience as a manufacturing or industrial engineer, with at least 3 years in HVAC or coil production strongly preferred.
• Must possess a Bachelor’s in Science in Engineering, or related field, from accredited educational institution. Education beyond the minimum is an added advantage for career development.
• Project management experience as a Manufacturing or Industrial Engineer.
• Proficient with lean manufacturing, 6-Sigma, or other continuous improvement methodologies.
