Combustion Engineer

About us: Prometheus Applied Technologies develops combustion solutions for spark-ignited engines running natural gas, biogas, hydrogen, methanol, and other lower-carbon fuels. Our work covers prechamber ignition, mixture preparation, adaptive spark control, and the CFD and test methods behind them. We support power generation, heavy-duty on/off road, gas compression, marine, and related engine programs from Fort Collins, Colorado.

The role: We are hiring a junior engineer who wants to build a career as a combustion simulation specialist. You will learn our development method by doing the work: geometry preparation, mesh, boundary conditions, combustion and flow simulation, and comparison to engine and optical data. This is a mentored role, not a solo CFD posting.

What you will do: Build and run CFD cases for in-cylinder flow, mixing, and combustion under guidance Prepare geometry and meshes from CAD; document assumptions and setups so others can repeat the work Compare simulation results with engine test data, optical measurements, and prior Prometheus cases Support design iterations on prechamber, intake-flow, and injector-related hardware Write clear notes, plots, and short technical summaries for the engineering team Learn our standards for simulation, validation, and customer deliverables

What we are looking for: Bachelor’s degree in mechanical engineering or a closely related field (recent graduate or early career)Coursework in thermodynamics, fluid mechanics, and heat transfer Exposure to CFD (ANSYS Fluent, CONVERGE, STAR-CCM+, OpenFOAM, or similar)—course projects count Comfort with CAD and engineering drawings Careful documentation and a willingness to follow an established method Ability to work on-site in Fort Collins and take direction from senior engineers Helpful, not required Engine lab, dyno, or data-acquisition experience Combustion, internal combustion engines, or reacting-flow coursework Python or MATLAB for post-processingFEA exposure

How to apply: Send a résumé, GPA, and a short note on one simulation or fluids project you completed (what you modeled and how you checked it).Prometheus Applied Technologies Fort Collins, Colorado
