The Company's expanding portfolio of equipment and software solutions is used in both the wafer processing and final manufacturing of ICs, and in adjacent markets such as FPD, and LED manufacturing.

We design and manufacture advanced semiconductor inspection and metrology tools. Our solutions power innovation for the world's leading chip makers. As the industry moves faster than ever, we believe AI will be a key enabler of smarter, faster, and more reliable decision-making in semiconductor manufacturing.

We're building a new AI Innovation Team to explore, develop, and deploy cutting-edge machine learning systems across our product and process ecosystem. You'll be our founding Lead AI Engineer, responsible for setting the vision, building the team, and delivering impactful AI solutions at scale.

About the Role

This is a hands-on technical leadership role. You will work closely with senior tool designers, process engineers, and applications teams to understand complex workflows and data flows. You'll architect, prototype, and product ionize AI solutions that accelerate innovation, improve yields, and reduce tool downtime. You will also grow and mentor a team of three engineers specializing in LLMs, computer vision, predictive modeling, and MLOps.

Responsibilities

* Define the AI strategy and architecture for integrating machine learning into core engineering and manufacturing processes.

* Partner with tool, process, and applications engineers to map as-is processes and define a to-be AI/automation architecture and deliver measurable outcomes.

* Ship agentic assistants for use-cases. Stand up LLM + RAG + tool integrations (via MCP servers) that help engineers accelerate tool operation/setup/maintenance and explain trade-offs, grounded in internal docs, logs, and historical inspection outcomes.

* Lead projects across diverse areas:

* Predictive maintenance for tool health monitoring and failure detection.

* Computer vision for wafer defect detection, segmentation, and classification.

* LLM-based engineering assistants using RAG and MCP agents to make internal knowledge more accessible.

* Process optimization & yield improvement through data-driven insights and parameter tuning.

* Simulation and digital twins to model process behaviors and accelerate R&D.

* Build retrieval-augmented AI assistants to query internal knowledge bases, tools, and logs.

* Architect robust pipelines for data ingestion, labeling, storage, and retrieval across massive multi-modal datasets (images, telemetry, recipes, logs).

* Stand up scalable MLOps infrastructure: model registries, monitoring, evaluation, deployment, and governance.

* Hire, mentor, and manage a team of 3 engineers focused on LLM/Agents, CV/ML, and MLOps/Data.

* Work cross-functionally to integrate AI solutions into production environments safely and securely.

Minimum Qualifications

* 5+ years applied ML/AI experience, with 3+ years in a technical leadership role.

* Hands-on expertise with at least two of the following domains:

* Large Language Models - RAG, fine-tuning, agent frameworks, prompt optimization.

* Predictive Modeling - tool failure prediction, anomaly detection, time-series analysis.

* Computer Vision - defect detection, segmentation, or SEM/optical imaging.

* Strong background in ML systems architecture and production deployment.

* Advanced Python proficiency: C++/CUDA familiarity is a plus.

* Experience with MLOps stacks: containers, CI/CD, Ray…
