Johnson Controls is seeking a Senior Data Scientist with a strong practical background in deploying production‑ready AI/ML solutions. This role focuses on developing advanced agentic AI systems, time‑series analytics, and signal‑processing capabilities to optimize our building technologies, HVAC systems, and industrial IoT platforms. This is a hybrid position (onsite 3 days per week) based in Glendale, WI. Candidates must be commuting distance, or able to relocate.

• Design and deploy agentic AI systems that autonomously optimize building operations, energy consumption, and equipment performance
• Develop and implement advanced time‑series forecasting models for energy demand, equipment behavior, and operational patterns
• Apply signal‑processing techniques to analyze sensor data, detect anomalies, and extract meaningful patterns from noisy industrial environments
• Build end‑to‑end machine learning pipelines from data ingestion through model deployment and monitoring in production systems
• Lead predictive maintenance initiatives using ML models to forecast equipment failures and optimize maintenance schedules
• Collaborate with engineering and operations teams to translate business problems into practical data science solutions
• Mentor junior data scientists and establish best practices for model development and deployment

• Bachelor's degree in Data Science, Computer Science, Engineering, Statistics, or related field
• 7+ years of professional experience developing and deploying ML/AI solutions in industrial, IoT, or similar environments
• Experience delivering at least 2-3 production ML models with measurable business impact
• Agentic AI & Machine Learning
• Hands‑on experience building agentic AI systems or autonomous decision‑making algorithms
• Knowledge of reinforcement learning, multi‑agent systems, or autonomous optimization frameworks
• Exposure to LLM‑based agents, tool use, or reasoning frameworks for decision‑making
• Solid understanding of supervised and unsupervised ML algorithms with deployment experience
• Time Series Analysis
• Experience with time‑series forecasting using methods like ARIMA, Prophet, LSTM, or similar approaches
• Hands‑on work with seasonal patterns, trend analysis, and time‑series decomposition
• Experience applying time‑series techniques to real‑world datasets (sensor data, energy consumption, etc.)
• Familiarity with handling missing data, outliers, and non‑stationary time series
• Signal Processing
• Working knowledge of digital signal processing including filtering, FFT, and spectral analysis
• Experience processing sensor data from industrial equipment (vibration, temperature, pressure, acoustic signals)
• Ability to implement feature extraction from signal data and apply noise reduction techniques
