What you'll do:

As an MBIST Diagnostics Engineer you will be responsible for leading the development of robust diagnostic flows that span the entire lifecycle of memory test—from initial diagnosis through repair validation to post-silicon debug. Your day-to-day activities will involve collaborating with cross-functional teams to architect scalable solutions for embedded memories in advanced SoCs. You will analyse complex fail logs from automated test equipment (ATE), develop sophisticated algorithms for failure signature analysis and redundancy management, implement automation tools for workflow optimisation using scripting languages like Python or Perl, and establish reusable methodologies that can be adopted across multiple products. By mentoring fellow engineers and influencing design decisions early in the product lifecycle you will help shape future strategies for memory-test technologies while accelerating yield learning and improving overall product quality. Success in this role requires a deep understanding of MBIST architecture combined with strong analytical skills applied to real-world silicon challenges.

• Lead comprehensive SRAM MBIST diagnosis activities across intricate SoC designs by analysing ATE datalogs, fail logs, MBIST fail signatures, repair data, and silicon debug results to isolate failures and determine root causes.
• Develop and refine advanced memory diagnostic methodologies including redundancy analysis, BIRA/BISR flows, ECC architectures, self-repair techniques, and post-repair validation processes to ensure optimal performance.
• Architect innovative MBIST diagnostic solutions for embedded memories such as 3DIC, 2.5D stacked memory, HBM, DRAM, and chiplet-based architectures while defining controller requirements and error logging mechanisms.
• Evaluate MBIST diagnostic strategies based on memory architecture nuances, fault models, repair capabilities, and silicon debug needs to optimise overall system reliability.
• Influence design-for-diagnostics hooks by establishing observability requirements and repair access paths during product development phases to enhance debug infrastructure.
• Establish reusable memory diagnostics methodologies adopted across multiple products and technology generations to standardise best practices within the organisation.
• Develop end-to-end 3DIC memory diagnostics flows covering wafer test procedures through known-good-die validation up to stack/package testing and system-level validation.
• Correlate manufacturing test results with silicon behaviour by performing fault localisation and root-cause analysis while supporting silicon bring-up activities.
• Create automation frameworks using Python, Perl or TCL scripting languages for fail-log parsing, MBIST signature analysis, repair classification and diagnostic reporting.
• Mentor engineers across product teams on memory diagnostics methodology while providing technical leadership in MBIST diagnostics initiatives.
