Job Summary:
We are looking for an experienced and technically driven Staff / Senior Staff Reliability Engineer to join our growing engineering team and play a critical role in bringing advanced semiconductor products successfully through the New Product Introduction (NPI) process from early definition through to production release.

In this role, you will take ownership of product reliability qualification activities, working closely with cross-functional engineering teams to design, execute, analyse, and report on reliability testing programs that directly impact product quality, customer confidence, and long-term product performance.

You will work across design, product engineering, test engineering, quality, manufacturing, and failure analysis teams to investigate qualification failures, predict product lifetime performance, and ensure reliability commitments are successfully delivered throughout the development lifecycle.

This is a high-impact technical role offering the opportunity to work on cutting-edge semiconductor technologies within a global engineering organisation focused on innovation and engineering excellence.

Responsibilities:

• Lead the planning and execution of product reliability qualification activities for new semiconductor products, process changes, and customer-driven qualification requests, including data analysis and formal technical reporting. (20%)
• Partner with Design, Product Engineering, Test Engineering, and Failure Analysis teams to investigate reliability qualification failures, identify root causes, and provide recommendations for corrective actions and product improvements. (20%)
• Perform product reliability modelling, lifetime calculations, and failure mechanism analysis using stress test data, ongoing reliability monitoring data, and field reliability performance information. (20%)
• Collaborate with Design Engineering, Test Engineering, and external vendors to design and develop reliability test hardware including HTOL and HAST boards used for qualification testing programs. (15%)
• Support Manufacturing Engineering, Operations, and Quality teams in evaluating manufacturing issues that may impact product reliability and assist with technical disposition decisions relating to held manufacturing lots. (15%)
• Review and maintain alignment with evolving semiconductor industry reliability standards including JEDEC, AEC, ESDA, IPC and other qualification frameworks while supporting customer requests relating to qualification data, FIT rates, and technical reliability inquiries. (10%)

Minimum Qualifications:

• Bachelor’s degree in Electrical Engineering, Electronics Engineering, Engineering Physics, or closely related discipline
• Minimum 5+ years of experience within Semiconductor Reliability Engineering
• Proven experience developing and executing semiconductor reliability qualification plans and formal qualification reporting
• Experience performing product lifetime calculations, reliability modelling, and qualification data analysis
• Demonstrated experience supporting semiconductor products through New Product Introduction (NPI) and production release activities
• Strong written and verbal communication skills with experience working across cross-functional engineering teams

Desired Qualifications

• Advanced knowledge of semiconductor industry standards including JESD47, JEP122, JS-001, JS-002, AEC-Q100, AEC-Q101 and AEC-Q006
• Strong understanding of semiconductor fabrication processes, assembly, test methodologies, and semiconductor device physics
• Working knowledge of MOSFET, BJT, and integrated circuit architecture fundamentals
• Working knowledge of ESD/LU testing and tools such MK1/MK2 would be highly advantageous
• Experience identifying semiconductor die and package failure mechanisms during reliability testing and failure analysis activities
• Experience using statistical and data analysis tools such as JMP, Minitab, Excel, and related engineering software tools
• Experience with DOE (Design of Experiment) methodologies and structured engineering experimentation
• Additional experience in Failure Analysis, Product Engineering, Test Engineering, Quality Engineering, Applications Engineering, Wafer Fabrication, or Product Validation would be highly advantageous
• Master’s Degree or PhD in a related engineering discipline would be considered beneficial

Why Join Us?

• Work on advanced semiconductor technologies powering critical global communications and connectivity infrastructure
• Join a highly collaborative engineering organisation working on next-generation product innovation
• Play a critical role in ensuring product quality, reliability, and successful delivery of cutting-edge technologies to market
• Collaborate with talented global engineering teams across product development, design, quality, manufacturing, and operations
• Build your career within a technically challenging environment focused on continuous innovation and engineering excellence
