Reliability Engineer — Advanced Thermal Management

Coherent Corp.•Clinton Township, PA

1d•$115,000 - $160,000•Hybrid

About The Position

This role is responsible for identifying applicable standards and test methods, developing reliability qualification plans, coordinating reliability testing, supporting failure analysis, and preparing customer-ready reliability data packages for advanced thermal management products. The engineer will lead and manage reliability test planning and execution for various thermal management products including semiconductor packaging, liquid cold plates, T800 Thermadite, CVD diamond, thermal spreaders, embedded cooling structures, and related thermal assemblies. The position involves translating customer requirements and expected failure mechanisms into robust reliability test plans and acceptance criteria, and supporting various reliability test methods. Collaboration with internal teams, customers, suppliers, and external labs is crucial for qualification strategy, test methods, sample sizes, success criteria, and reporting. The role also includes supporting failure analysis efforts, translating findings into actionable recommendations, and supporting customer technical reviews and product scale-up decisions.
