About Semtech and Our Team
At Semtech Corporation, innovation is at the heart of everything we do. Our advanced semiconductor technologies power critical communications infrastructure, high-performance connectivity solutions, and next-generation electronic systems, serving markets including industrial, automotive, data centres, and IoT worldwide.
To support our expanding product portfolio, ensuring exceptional product quality and long-term reliability is paramount. We are reinforcing our Reliability Engineering function within our global engineering organisation and seek an experienced technically driven _Staff / Senior Staff Reliability Engineer_** to join our team, ensuring product excellence from early definition through production release.
Job Summary
We are seeking a highly skilled Reliability Engineer to play a critical role in bringing cutting-edge semiconductor products through the New Product Introduction (NPI) process. You will lead product reliability qualification activities, working with cross-functional engineering teams to:
- Design and execute reliability testing programs
- Analyse and report on qualification data
- Collaborate with design, test, failure analysis, and manufacturing teams to investigate failures, predict lifetime performance, and ensure reliability goals
- Support product validation, customer-driven requirements, and industry standards compliance
This high-impact technical role offers the opportunity to work on next-generation semiconductor technologies within an innovative, global engineering team.
Responsibilities
-
Product Reliability Qualification (20%)
Lead the development and execution of reliability qualification plans for new semiconductor products, process changes, and customer-driven requests. Ensure data analysis and formal technical reporting align with engineering standards.
-
Failure Investigation & Root Cause Analysis (20%)
Partner with Design, Product Engineering, Test Engineering, and Failure Analysis teams to investigate reliability qualification failures. Identify root causes and recommend corrective actions for product improvements.
