Job Description

Sandisk understands how people and businesses consume data and we relentlessly innovate to deliver solutions that enable today’s needs and tomorrow’s next big ideas. With a rich history of groundbreaking innovations in Flash and advanced memory technologies, our solutions have become the beating heart of the digital world we’re living in and that we have the power to shape.

Sandisk meets people and businesses at the intersection of their aspirations and the moment, enabling them to keep moving and pushing possibility forward. We do this through the balance of our powerhouse manufacturing capabilities and our industry-leading portfolio of products that are recognized globally for innovation, performance and quality.

Sandisk has two facilities recognized by the World Economic Forum as part of the Global Lighthouse Network for advanced 4IR innovations. These facilities were also recognized as Sustainability Lighthouses for breakthroughs in efficient operations. With our global reach, we ensure the global supply chain has access to the Flash memory it needs to keep our world moving forward.

We are seeking an experienced and visionary Sr. Technologist to join our organization in Milpitas, United States. This role is director‑equivalent in scope and impact, with a strong emphasis on technical leadership and hands‑on innovation rather than large team management.

In this pivotal role, you will establish and lead an AI Systems & Performance Lab focused on identifying and eliminating AI bottlenecks across real‑world workloads, software stacks, and diverse hardware configurations. You will define the lab’s technical vision, develop rigorous methodologies, and deliver insights that directly influence system architecture, platform strategy, and future hardware designs.

The ideal candidate brings deep expertise in AI workloads and system performance, paired with the ability to translate complex technical findings into clear architectural and business impact.

Essential Duties and Responsibilities:

AI Lab Vision & Technical Leadership

• Establish and articulate a clear technical vision and charter for the AI Lab, focused on AI workload characterization and performance bottleneck analysis.
• Define the research agenda, success metrics, and execution model aligned with organizational objectives and future technology directions.
• Serve as the technical authority for AI systems performance and workload analysis.

AI Workload & System Bottleneck Analysis

• Drive end‑to‑end analysis of AI training and inference workloads, spanning models, frameworks, runtimes, and full system stacks.
• Identify performance bottlenecks across compute, memory hierarchy, interconnects, storage, power, and software layers.
• Develop repeatable methodologies for root‑cause analysis across heterogeneous platforms (CPU, GPU, NPU, and custom accelerators).

Benchmarking & Infrastructure Development

• Architect and oversee the development of benchmarking, profiling, and workload characterization frameworks.
• Evaluate AI performance across multiple hardware configurations and system topologies, ensuring rigor, reproducibility, and scalability.
• Establish best practices for performance measurement, regression tracking, and comparative analysis.

Cross‑Functional Influence

• Partner closely with hardware, platform, and system architecture teams to translate workload insights into actionable design recommendations.
• Collaborate with AI software, product, and business teams to ensure performance findings inform roadmap and investment decisions.
• Influence next‑generation system and silicon direction using data‑driven insights from real workloads.

Technical Mentorship & Thought Leadership

• Provide technical mentorship and guidance to a small, highly skilled team of engineers and researchers.
• Drive thought leadership through internal publications, external papers, or patents in AI systems and performance engineering.
• Represent the AI Lab in technical reviews, architecture forums, and executive briefings.

Responsible AI & Governance

• Ensure AI performance research and system recommendations align with responsible and ethical AI principles.
• Incorporate considerations around efficiency, sustainability, and scalability into workload and system analysis.

Qualifications

Required:

• Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or a related technical field; Master’s or PhD strongly preferred.
• 15+ years of industry experience in systems engineering, AI infrastructure, performance engineering, computer architecture, or hardware/software co‑design.
• Deep hands‑on experience with AI workloads (training and/or inference), including modern deep learning models and frameworks (e.g., PyTorch, TensorFlow, JAX, or equivalent).
• Strong understanding of end‑to‑end system performance, including compute architectures, memory hierarchy, interconnects, storage, and software stacks.
• Proven ability to identify, analyze, and root‑cause performance bottlenecks across heterogeneous systems (CPU, GPU, NPU, accelerators).
• Demonstrated technical leadership with director‑level influence, driving strategy and outcomes without relying on large teams.
• Experience translating complex technical findings into clear architectural recommendations and business‑relevant insights.
• Excellent written and verbal communication skills, with experience presenting to senior technical and executive stakeholders.

Preferred:

• PhD or equivalent industry experience in AI systems, computer architecture, performance modeling, or large‑scale distributed systems.
• Hands‑on experience with AI accelerators (e.g., GPUs, NPUs, custom silicon) and their software ecosystems.
• Background in benchmarking, profiling, and workload characterization, including development of custom tools or frameworks.
• Experience influencing platform, system, or silicon roadmaps using workload‑driven, data‑backed insights.
• Familiarity with compiler stacks, runtimes, and low‑level performance analysis tools.
• Track record of technical thought leadership, including patents, publications, standards contributions, or widely adopted internal frameworks.
• Experience working across hardware, software, and product organizations in highly matrixed environments.

Leadership & Role Fit

• Comfortable operating as a senior technical authority with broad organizational influence and limited direct reports.
• Demonstrated ability to build new technical capabilities from scratch, including labs, methodologies, and infrastructure.
• Strong mentoring mindset, guiding senior and junior engineers through technical depth rather than formal management.
• Pragmatic, results‑oriented approach with the ability to balance research rigor and product impact.
