Lead Reliability and Quality Engineer (Optical Systems)

Coherent Corp. Vietnam•Sunnyvale, CA

6h•Onsite

About The Position

Primary Duties & Responsibilities Lead reliability strategy development for new optical product platforms, ensuring robust design and manufacturability from early architecture stages through production ramp. Collaborate closely with optical designers, mechanical engineers, process engineers, manufacturing teams, and suppliers to identify technical risks and implement mitigation plans to prevent product failures. Lead root cause investigations and failure analysis activities, leveraging physics-of-failure principles and structured problem-solving techniques (8D, DMAIC, etc.). Drive quality improvements through process optimization, data-driven decision making, and continuous improvement methodologies (Lean, Six Sigma, SPC). Establish and improve quality systems, procedures, and metrics appropriate for a dynamic, startup-oriented environment while maintaining compliance with corporate and industry standards. Define and execute comprehensive qualification and validation plans to ensure product robustness, lifetime performance, and compliance with internal and customer reliability requirements. Develop and implement reliability test methodologies including accelerated life testing, environmental stress screening, HALT/HASS, and aging studies. Analyze reliability data using statistical methods to estimate lifetime performance, failure rates, and confidence levels; clearly communicate findings to technical and executive stakeholders. Partner with suppliers to evaluate process capability, manufacturing readiness, and long-term reliability risks. Support production ramp activities, ensuring scalability, yield improvement, and sustained reliability performance.Lead reliability strategy development for new optical product platforms, ensuring robust design and manufacturability from early architecture stages through production ramp.
