[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
