[Remote] Physical Systems Modeler - 1D Simulation

Note: The job is a remote job and is open to candidates in USA. P-1 AI is a company focused on building engineering AGI with a product named Archie that enhances engineering capabilities. The Physical Systems Modeler - 1D Simulation will develop simulators and component models to generate synthetic training data for Archie, ensuring high-quality datasets that reflect real-world behavior of physical systems. 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 Skills Have built 1D physics-based physics in languages like Julia (ModelingToolkit) or Modelica (Dymola, OpenModelica), Simulink Understand thermodynamics, heat transfer, and fluid mechanics at an engineering level Can derive governing equations from first principles and implement them numerically Have experience with numerical methods for ODEs/DAEs and understand solver trade-offs Experience in Mechanical, Chemical, or Electrical Engineering Experience with HVAC system modeling or building energy simulation Prior work simulating a large number of system configurations for design space exploration Contributed to open-source modeling projects (SciML, OpenModelica, Modelica Standard Library) Experience with FMI/FMU model export and co-simulation Are fluent in Python for data processing and pipeline integration Benefits Healthcare Dental Vision insurance 401k with employer matching Unlimited PTO Company Overview P-1 AI is a technology company focused on developing an artificial general engineering intelligence (AGEI).
