Responsibilities
Develop acausal component models: Build reusable, parameterized models of HVAC and electrical equipment from first principles that can be used for trade studies
Generate synthetic training datasets: Design parameter sweeps and scenario matrices that cover the operating envelope of real equipment, including off-design and fault conditions
Validate models against real-world data: Engage with expert engineers for model review, calibrate simulations to manufacturer specs or field measurements from customer deployments
Integrate with ML pipelines: Work with AI engineers to format, label, and deliver simulation outputs for model training and evaluation
Build and maintain component libraries: Create well-documented, tested libraries that scale across equipment types and can be composed into system-level models
