Job Description

We are seeking a Senior Staff AI/ML Engineer to lead the design, development, and deployment of advanced AI/ML and Generative AI solutions that drive innovation across our engineering, manufacturing, and business operations.

This role requires deep expertise in machine learning engineering, data science methodologies, and large-scale AI systems, combined with strong domain intuition in semiconductor/NAND environments. You will operate at the intersection of data, models, and real-world systems, translating complex, high-impact problems into scalable AI solutions.

Key Responsibilities

AI/ML, Data Science & Domain Integration

• Develop advanced machine learning, statistical, and optimization models to solve complex business and engineering problems
• Apply end-to-end data science rigor: problem framing, feature engineering, modeling, validation, and impact measurement
• Work with large-scale datasets (e.g., process, yield, test, operational data) to derive actionable insights
• Integrate domain knowledge (semiconductor/NAND processes, constraints, variability) directly into model design and interpretation

Generative AI & Intelligent Systems

• Design and deploy GenAI solutions (LLMs, RAG pipelines, agent-based systems) for engineering and operational use cases
• Build knowledge-driven systems leveraging enterprise data (documents, logs, process data)
• Develop evaluation frameworks to ensure quality, grounding, and reliability of GenAI outputs
• Apply GenAI to enable decision support, automation, and productivity at scale

End-to-End System Architecture

• Architect production-grade AI/ML systems, including:
• Data pipelines and feature engineering frameworks
• Model training and experimentation platforms
• Real-time and batch inference systems
• Design systems that balance accuracy, scalability, latency, and cost efficiency
• Establish patterns for integrating AI into existing enterprise platforms and workflows

MLOps & Production Excellence

• Build and scale MLOps pipelines (CI/CD, model registry, monitoring, drift detection)
• Ensure reproducibility, observability, and governance of AI systems
• Lead efforts to operationalize models into reliable, maintainable production systems

Collaboration & Mentorship

• Partner with cross-functional teams (engineering, manufacturing, product, IT) to translate requirements into solutions
• Mentor engineers and data scientists in advanced modeling, system design, and GenAI capabilities

Qualifications Required

• Master’s degree in Computer Science, Electrical Engineering, Statistics, Applied Mathematics, or a related quantitative field
• 8–12+ years of experience in AI/ML engineering, data science, or related domains
• Strong expertise in:
• Python and modern ML frameworks (PyTorch, TensorFlow, scikit-learn)
• Statistical modeling, experimentation, and data science methodologies
• Scalable ML system design and production deployment
• Proven track record of delivering production-grade AI/ML systems with measurable business impact

Preferred

• PhD in a relevant field (e.g., Machine Learning, AI, Statistics, Operations Research, Electrical Engineering) with significant industry experience
• Deep experience applying AI/ML in complex, real-world systems (e.g., semiconductor, manufacturing, or large-scale operational environments)
• Hands-on experience with:
• Generative AI / LLM systems (RAG, prompt engineering, evaluation frameworks, fine-tuning)
• MLOps platforms (MLflow, Azure ML, Kubeflow, or equivalent)
• Distributed data platforms (Spark, Databricks)
