Position Summary

Infleqtion is poised for significant growth after completing our transition to a publicly traded company (NYSE ticker symbol “INFQ”). We are seeking a Senior Supplier Quality Engineer to drive supplier quality, resolve complex manufacturing issues, and strengthen supplier quality processes. This role will work closely with Engineering, Supply Chain, Purchasing, and Quality to ensure suppliers consistently meet technical specifications, manufacturing requirements, and quality standards.

• Qualify and develop suppliers through capability assessments, first article inspections, risk evaluations, and continuous improvement initiatives.
• Develop and improve supplier quality processes, including supplier approval, incoming inspection, change management, escalation, and performance monitoring.
• Investigate supplier nonconformances, distinguish manufacturing defects from internal specification issues, and drive appropriate resolutions.
• Plan and conduct internal supply chain and external supplier audits covering purchasing controls, traceability, inventory accuracy, receiving inspection, and corrective action effectiveness.
• Support applicable AS9100 quality management requirements and SOX compliance activities in collaboration with cross-functional teams.

· Proficiency interpreting engineering drawings, specifications, bills of material, inspection plans, test requirements, and configuration-control requirements.

· Experience with nonconformance management, material review, root-cause analysis, corrective and preventive action (CAPA), and supplier corrective action requests (SCARs).

· Ability to develop and review quality plans, first-article inspection packages, inspection/test records, certificates of conformance, and traceability documentation.

· Experience applying quality tools such as 5 Why, fishbone analysis, FMEA, control plans, process capability, statistical process control, and risk-based thinking.

· Strong documentation discipline and ability to maintain objective quality evidence that is complete, accurate, traceable, and ready for customer or Government review.

· Effective communication and collaboration skills with suppliers, procurement, engineering, manufacturing, program management, and customers.
