Reliability Engineer

Role Summary

We are seeking a talented and motivated Reliability Engineer to join our team. You will play a crucial role in ensuring the reliability, performance, and safety of our products at multiple levels of the manufacturing process is proven through defined, industry standard semiconductor and satellite communication product qualification programs.

Responsibilities

The core responsibilities include:

• Conduct reliability testing and analyses to identify failure points at IC, IC package, Module and Motherboard level.

• Develop and execute reliability test plans for semiconductor devices, including stress testing, accelerated life testing, and environmental testing.

• Implement and maintain reliability modelling and prediction tools to assess the long-term performance of semiconductor devices.

• Investigate root causes of failures, analyse failure data, and make recommendations to enhance product reliability.

• Interpret customer qualification requirements and support all new product qualification proposals.

• Develop and maintain reliability models, metrics, and documentation to support product development and reliability improvement efforts.

• Contribute to the development of reliability documentation, including reliability plans, reports, and specifications.

• Work closely with cross-functional teams, including design, process engineering, and quality assurance, to integrate reliability considerations into the product development process.

• Conduct risk assessments, including Failure Mode and Effects Analysis (FMEA), to proactively identify potential failure modes and mitigation strategies.

Person Specification

Need to Have

• Experience in applying reliability tools and methodologies, such as Weibull analysis, accelerated life testing, reliability prediction, and root cause analysis.
