Job description

Join Utility Global

The Role

Utility Global is expanding into numerous industrial sectors and looking for a Senior Simulation Engineer to join our Applied Technology Team in Englewood, Colorado. As part of our organization, you will work with a highly motivated and driven team to leverage simulation as a tool to drive commercial electrochemical module design, help design experiments and interpret results, and to support cross-functional teams as required.

Key Responsibilities

• Develop and execute high-fidelity CFD simulations (Ansys Fluent preferred) for thermal-fluid and reacting flow systems.
• Lead simulation strategy for complex engineering challenges, ensuring models are physics-based, robust, and decision-driving.
• Design, build, and support hands‑on experimental setups to validate simulation predictions.
• Develop validation plans that define measurable metrics, instrumentation requirements, and acceptance criteria.
• Analyze experimental and pilot‑scale data, reconciling discrepancies between modeled and observed behavior.
• Iterate models based on empirical results to improve predictive accuracy and reduce uncertainty.
• Support mechanical and process design through simulation-informed decision-making and CAD collaboration (SolidWorks preferred).
• Collaborate cross‑functionally with engineering, operations, and technician teams to troubleshoot systems and drive root‑cause investigations.

Candidate Profile

• Minimum of 5 years post graduate degree, preferably 10+ years of engineering experience in Mechanical Engineering, Chemical Engineering, or related engineering discipline (advanced degree strongly preferred).
• Deep CFD expertise, including mesh strategy, solver setup, turbulence modeling, reacting flows, and multimode heat transfer.
• Demonstrated experience coupling simulations with real‑world experimental testing and pilot‑scale systems.
• Strong hands‑on experience running experiments, supporting production trials, or operating pilot hardware.
• Proven track record of validating simulation results against experimental data and improving model fidelity.
• Experience designing test plans, instrumentation layouts, and experimental methodologies.
• Proficiency in CAD tools (SolidWorks preferred) with practical understanding of manufacturable hardware design.
• High emotional intelligence, strong communication skills, and ability to thrive in a collaborative, cross‑functional applied R&D environment.
