·        Partner with Collins commodity teams to support supplier selection and strategic regional supplier development initiatives.

·        Lead technical evaluation activities during supplier onboarding and industrialization phases.

·        Manage and support RFQ activities across multiple business units by evaluating supplier manufacturing capabilities, cost drivers, technical risks, and execution readiness.

·        Develop long-term supplier capability roadmaps to support business growth, risk mitigation, and supply chain diversification strategies.

Supplier-Focused Technical Leadership

·        Serve as the primary technical authority for machining and fabrication processes across key global suppliers.

·        Conduct on-site supplier capability assessments, technical deep dives, manufacturing readiness reviews, and production risk evaluations.

·        Provide expert guidance on machining parameters, tooling strategies, fixturing, inspection methods, process control, and manufacturing optimization.

·        Serve as the Subject Matter Expert (SME) for supplier-facing technical discussions and manufacturing issue resolution.

·        Quickly assess manufacturing challenges and provide hands-on support to restore production stability and quality performance.

Advanced Machining, Programming & Fabrication Expertise

·        Lead detailed manufacturability assessments (DFM/A) and influence product design for producibility, cost, and quality.

·        Define and approve complex manufacturing plans for high-precision aerospace components produced from aluminum, titanium, nickel alloys, stainless steel, and other aerospace-grade materials.

·        Possess hands-on knowledge of CNC programming principles, machining processes, cutting tool selection, workholding strategies, and process optimization techniques.

·        Evaluate machining programs, tooling requirements, inspection strategies, and quality control methods to ensure robust manufacturing execution.

·        Support suppliers in establishing optimized process flows, machining strategies, setup reduction initiatives, and error-proofing methods.

·        Identify manufacturing risks early and implement preventive actions to ensure successful production launches.

APQP Leadership & Industrialization Governance
·        Lead Pre-FAI activities with suppliers to verify manufacturing readiness and ensure parts are produced correctly the first time.

·        Ensure suppliers meet manufacturing maturity, process capability, and quality requirements prior to key program milestones.

·        Validate manufacturing processes before formal FAI execution to minimize launch risk and reduce non-conformance.

·        Identify systemic risks and partner with suppliers on long-term corrective and preventive actions.

Supplier Performance Improvement

·        Lead major technical recovery and stabilization efforts at underperforming suppliers.

·        Drive continuous improvement in quality, productivity, takt time, yield, delivery performance, and cost using Lean Manufacturing and Six Sigma methodologies.

·        Serve as the technical escalation leader for severe supplier manufacturing and quality issues.

·       Develop and execute supplier improvement plans focused on sustainable operational excellence.

Critical Issue Resolution

·        Lead root cause analysis (RCCA/8D) for machining defects, dimensional instability, material issues, special process failures, and chronic yield problems.

·        Facilitate cross-functional collaboration between suppliers, quality, engineering, sourcing, and program management teams.

·        Provide rapid troubleshooting support for machining, programming, tooling, inspection, and manufacturing process issues.

·        Ensure corrective actions are effectively implemented, verified, and sustained.

Documentation, Compliance & Change Management

·        Oversee supplier compliance with aerospace standards (AS9100, AS9102) and internal manufacturing governance requirements.

·        Guide suppliers through engineering change implementation, configuration control, and manufacturing process changes.

·        Prepare technical reports, supplier risk assessments, capability evaluations, and executive-level status updates.

·        Support supplier audits, qualification reviews, and customer-facing manufacturing readiness activities.
