Fluid Dynamics Engineer
About The Position
Kunin Technologies is revolutionizing the critical mineral supply chain by implementing advanced separation technologies to capture value from overlooked resources. As ore grades plummet globally, traditional extraction methods are failing. Kunin Technologies utilizes breakthrough performance, ion-exchange media significantly more value can be produced from each resource, reducing waste, and unlocking metal abundance. This role is responsible for the flow behavior inside the module: inlet and outlet manifolds, distribution across elements, pressure drop, channeling, dead zones, residence time, and mass transfer. Your CFD models and measurements decide the module's internal geometry and its performance specification. You are part of a new team in Chattanooga, TN dedicated to the module: how fluid moves through the housing and its elements, how the hardware is engineered and sourced, and how elements become finished modules at production rate. This role matures to cover the hydraulic scale-up of modules across sizes and applications, in-line hydraulic QA methods, and performance modeling that feeds directly into customer project design. By the end of Q4 2027, we expect our media production line to be integrated with automated assembly into finished modules. By 2030, we want to be the world’s largest producer of ion-exchange equipment solutions. This role requires collaborating with internal production and operations teams & external joint-development partners.
Requirements
- Bachelor’s degree in mechanical, chemical, or aerospace engineering
- 1+ years of experience with CFD tools such as ANSYS Fluent, COMSOL, or OpenFOAM.
- Experience with experimental flow measurement: pressure, flow rate, and tracer or dye studies.
- 1+ years of experience using software tools such as Matlab or Python.
- Ability to work in fast paced and demanding atmosphere
- Creative problem solving that brings together fluid mechanics, porous media flow, separation chemistry, and mechanical design disciplines.
- Must be a U.S. citizen.
Nice To Haves
- advanced degree a plus.
Responsibilities
- Model flow through modules and their elements: manifold design, distribution across elements, pressure drop, channeling, and residence time distribution, using CFD and reduced-order models
- Design and run bench flow loops to validate models: pressure, flow, and tracer measurements on single elements and full modules
- Module internals design with the mechanical engineer: inlet and outlet headers, element seating and seals, spacers, and flow distribution hardware
- Mass transfer and breakthrough performance characterization – working with our chemists
- Hydraulic test protocols and QA specifications for production modules
Benefits
- equity
- Tennessee has no income tax
