Job Description:

Techtronic Industries (TTI) Outdoor Products is seeking a Sr. CFD Engineer with extensive experience in aerodynamic system design and optimization using reduced order modeling and computational fluid dynamics (CFD). This role will utilize CFD to optimize airflow dynamics for TTI’s next generation leaf blowers, lawn mowers, string trimmers, and other outdoor lawn and garden products. It will involve both steady state analysis for design optimization as well as transient analysis for acoustics and identification of system instabilities. The Sr. CFD Engineer will be a member of the Advanced Analytical Engineering team and will help drive key decisions related to aerodynamics, rotor design, and aeroacoustics while working closely with Project Engineering teams across the Outdoor Products business unit. This is an interdisciplinary position and requires a high degree of self-motivation. Technical skills and willingness to learn are essential.
