Sr. AI / ML Research Engineer

Description - External

At Trane Technologies and through our businesses including Trane and Thermo King, we create innovative climate solutions for buildings, homes, and transportation that challenge what’s possible for a sustainable world. We’re a team that dares to look at the world’s challenges and see impactful possibilities. We believe in a better future when we uplift others and enable our people to thrive at work and at home. We boldly go.

We are seeking a Sr. AI / ML Research Engineer to help build next-generation physics-based AI capabilities for fluid and thermal systems. This role is ideal for a candidate who combines deep expertise in computational fluid dynamics, scientific computing, and modern machine learning to accelerate simulation, design optimization, and digital engineering workflows.

The ideal candidate will bring hands-on experience applying physics-informed neural networks, neural operators, surrogate modeling, reduced-order modeling, and related scientific ML methods to real engineering problems. They will work across research and product teams to translate advanced methods into robust, production-oriented solutions that improve simulation speed, fidelity, and decision-making.

What’s in it for you

Be a part of our mission!

As a world leader in creating comfortable, sustainable, and efficient environments, it is our responsibility to put the planet first. For us at Trane Technologies, sustainability is not just how we do business—it is our business. If you want to apply advanced AI to high-impact engineering systems and help define the future of physics-based product development, we invite you to join us.

In this role, you will

Develop and apply AI/ML methods for CFD and multi-physics simulation problems, especially in fluid flow, heat transfer, turbulence, and system-level thermal management.
Build physics-informed neural networks and related scientific ML approaches for forward modeling, inverse problems, parameter estimation, data assimilation, and hybrid simulation workflows.
Create surrogate and reduced-order models that accelerate high-fidelity simulation while preserving engineering accuracy.
Apply Design of Experiments methods to simulation campaigns, data generation strategies, sensitivity analysis, and efficient exploration of high-dimensional design spaces.
Work with structured and unstructured simulation data from commercial and open-source solvers such as ANSYS Fluent, STAR-CCM+, OpenFOAM, Moldflow, or similar platforms.
Design training, validation, and benchmarking workflows for scientific ML models using both simulated and experimental datasets.
Partner with domain experts, software engineers, and product teams to deploy research into usable tools and scalable engineering workflows.
Partner with external vendors and strategic technology providers to evaluate, adapt, and transition advanced AI/ML solutions into scalable in-house capabilities and engineering workflows.
Contribute to technical strategy in physics AI, scientific machine learning, model validation, and engineering optimization.
Communicating results clearly to technical and non-technical stakeholders and support adoption across the organization.
