As an AI / Machine Learning Engineer, you’ll design, develop, and deploy production AI solutions across machine learning, deep learning, reinforcement learning, and AI agents. A key focus of this role is using reinforcement learning (RL) to optimize dynamic manufacturing decisions such as scheduling, dispatching, planning, and resource allocation. You’ll work with simulation environments, operational data, and real-world feedback to build intelligent systems that can learn, adapt, and improve complex factory operations. What You’ll Do • Design, train, evaluate, and deploy machine learning and deep learning models. • Develop reinforcement learning solutions for complex decision-making and optimization problems. • Build RL environments, reward functions, policies, and evaluation frameworks. • Train and optimize agents using simulation and operational data. • Explore techniques including policy optimization, model-based RL, multi-agent systems, and hierarchical learning. • Build scalable training, inference, monitoring, and retraining workflows. • Partner with software engineers to integrate AI capabilities into production and customer-facing products. • Contribute to MLOps, experiment tracking, model versioning, observability, and lifecycle management. • Research and prototype emerging technologies including Generative AI, Agentic AI, LLMs, RAG, and multi-agent systems. • Collaborate with data scientists, software engineers, cloud architects, and semiconductor domain experts. What We’re Looking For Required • Strong foundation in machine learning and deep learning. • Hands-on experience building and deploying production ML systems. • Strong Python development skills. • Experience with PyTorch and/or TensorFlow. • Demonstrated experience developing reinforcement learning solutions. • Strong understanding of RL concepts including environments, policies, rewards, value functions, and exploration strategies. • Experience with modern RL methods such as PPO, SAC, DQN, Actor-Critic, or similar approaches. • Experience training and evaluating RL agents in simulation environments. • Ability to formulate complex optimization problems as reinforcement learning problems. • Experience with Git, testing, code reviews, CI/CD, and production software development. Preferred • Experience building AI agents or autonomous decision-making systems. • Experience with discrete-event simulation or simulation-driven learning. • Experience combining RL with optimization techniques. • Knowledge of scheduling, dispatching, operations research, or industrial optimization. • Experience with Azure, AWS, or Google Cloud, Docker, Kubernetes, or MLflow. • Experience with Generative AI, LLMs, agent frameworks, or RAG. • Semiconductor manufacturing experience is a plus.     Why This Role Reinforcement learning is a core strategic capability for this team, not simply a research topic. You’ll help develop next-generation manufacturing optimization solutions and intelligent agents capable of learning and adapting to complex factory operations. You’ll join an experienced, collaborative team of data scientists, AI engineers, software developers, and cloud architects working on challenging industrial AI problems with direct customer and business impact. Additional Information Time Type: Full time Employee Type: Assignee / Regular Travel: Yes, 10% of the Time Relocation Eligible: No The salary offered to a selected candidate will be based on multiple factors including location, hire grade, job-related knowledge, skills, experience, and with consideration of internal equity of our current team members. In addition to a comprehensive benefits package, candidates may be eligible for other forms of compensation such as participation in a bonus and a stock award program, as applicable. For all sales roles, the posted salary range is the Target Total Cash (TTC) range for the role, which is the sum of base salary and target bonus amount at 100% goal achievement.
