Position: Staff Engineer – Systems Simulation & Thermal Engineering

Location: Remote (Mexico)

Job Summary

We are seeking a Staff Engineer with strong expertise in systems simulation, thermal engineering, and product development to lead complex engineering and New Product Introduction (NPI) programs. The role will focus on high-fidelity system modeling, simulation-driven design, optimization, physical validation, and supporting controls development.

The ideal candidate will have hands-on experience with Modelica/Dymola, HVAC&R; or refrigeration systems, Python/Julia automation, Model-in-the-Loop (MiL), DOE, and multi-objective optimization, along with the ability to drive technical decisions across cross-functional engineering teams.

Key Responsibilities

- Lead system-level and component-level simulation for complex thermal/HVAC&R; systems.
- Develop and maintain high-fidelity Modelica/Dymola models and reusable component libraries.
- Drive simulation strategy for NPI and new technology development programs.
- Develop and deliver FMU/FMI models for Model-in-the-Loop controls validation.
- Apply DOE, Monte Carlo, tradespace analysis, and multi-objective optimization to evaluate design alternatives and system performance.
- Develop Python/Julia automation for parameter studies, data processing, simulation workflows, and performance analysis.
- Lead simulation-to-test correlation and physical validation activities.




- Translate simulation results into actionable engineering and architecture decisions.
- Establish simulation methodologies, validation standards, and engineering best practices.
- Collaborate closely with design, controls, testing, and product engineering teams.
- Mentor engineers and provide technical leadership on simulation-driven product development.

Required Qualifications
- 7+ years of experience in systems simulation, thermal engineering, mechanical engineering, or related product development.
- Strong hands-on experience with Modelica/Dymola and system-level modeling.
- Experience with HVAC&R;, refrigeration, heat transfer, or thermal systems.
- Strong programming/automation skills in Python and/or Julia.
- Experience with FMU/FMI and Model-in-the-Loop (MiL) integration.
- Strong understanding of DOE, statistical analysis, optimization, and simulation validation.
- Experience supporting NPI, product development, or new technology introduction.
- Strong problem-solving and technical leadership capabilities.
- Ability to work effectively with integral, cross-functional engineering teams.

Preferred Skills

- TIL Suite / JuliaSim
- modeFrontier
- MATLAB/Simulink
- Ansys Fluent / CFD
- Minitab / Six Sigma
- APQP, DFMEA, and DVP&R;
- Git / Azure DevOps
- Refrigeration cycle modeling and compressor performance analysis
