Mechanical Engineer, Thermal & Fluid Systems

At Switch, we don’t just design, build and operate data centers—we are enabling the technology of the future. Led by Founder & CEO, Rob Roy, we believe in revolutionary innovation, operational excellence and the principle of karma. Switch is where talented people come together to EVOLVE the digital world.

We believe that innovation isn’t just about technology—it’s about the people, culture, and purpose that make it happen. Every Switch team member contributes to a mission greater than themselves: to create the world’s most advanced digital infrastructure that powers the progress of humanity.

As a Mechanical Engineer, you will design, model, and validate thermal and fluid systems used in Switch data center environments. This role exists to improve cooling performance, efficiency, and scalability through simulation-driven engineering and system modeling.

You will leverage CFD, 3D modeling, and system simulation tools to validate designs and support development of digital twin capabilities. Your work directly informs design decisions and supports Product Development, Design Engineering, and Construction teams.

Develop 3D CAD models for piping and fluid cooling systems

Perform CFD simulations to evaluate thermal and airflow performance

Conduct system-level simulations to assess cooling infrastructure performance

Analyze chiller and environmental performance under varying conditions

Support development of digital twins through simulation outputs and visualization

Collaborate with Design Engineering and Construction teams to validate system performance

Participate in system modeling activities using SysML or similar frameworks

Prepare and present technical reports based on simulation results

Contribute to continuous improvement of thermal and fluid system design practices

You apply strong fundamentals in heat transfer and fluid dynamics

You approach modeling and design with precision and attention to detail

You translate simulation results into practical engineering decisions

You communicate technical concepts clearly across teams

You collaborate effectively in cross-functional environments

You take ownership of work from modeling through validation

Required:

Bachelor’s degree in Mechanical Engineering (or related field) with 3+ years of experience, or Master’s degree with 1–2 years of experience

Strong background in heat transfer and fluid dynamics

Experience performing CFD simulations

Experience designing 3D CAD models for mechanical systems

Experience with industrial cooling systems, including chillers and piping

Ability to read and interpret piping diagrams and engineering schematics

Experience with CAD tools (e.g., Solid Works, Siemens NX, or PTC Creo)

Experience with CFD tools (e.g., ANSYS or similar)

Strong problem-solving skills and attention to detail

Preferred:

Experience in data center or AI infrastructure environments

Familiarity with system-level modeling tools (e.g., SysML, CATIA Magic)

Experience in rapid prototyping or product development environments

Exposure to power or infrastructure systems
