Job description

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.

ABOUT TTI

Techtronic Industries (TTI) is a world leader in Power Tools, Accessories, Hand Tools, Outdoor Power Equipment, and Floor Care for Do-It-Yourself (DIY), professional and industrial users in the home improvement, repair, maintenance, construction, and infrastructure industries.

Primary Responsibilities

• Serve as subject matter expert in topics related to CFD including turbulent flow modeling techniques, acoustics, and heat transfer.
• Design axial fan/stator systems to meet performance metrics including flow rate, blow force, pressure ratio, efficiency, stall margin, and noise reduction through use of CFD and reduced order modeling
• Collaborate with multidisciplinary teams to optimize product design to meet performance, size, cost, noise, and manufacturability requirements
• Develop and validate analytical models to predict system behaviors across a range of operating conditions for tools such as leaf blowers, lawn mowers, string trimmers, BLDC motors, and other tools with rotary components
• Perform experimental testing of system components and full tools to validate models and refine design methodologies
• Develop design optimization techniques to improve power requirements, noise levels, and performance metrics for consumer products
• Model airflow in complex environments to improve flow patterns, noise reduction, and heat transfer
• Measure various properties and performance metrics to support new and mature product development
• Prepare detailed design documentation and presentations to communicate analysis results, design recommendations, and project status to project stakeholders
• Provide training to junior personnel in analytical tools, interpretation of results, and decision-making processes for successful airflow system design
• Maintain current knowledge of developments in the field to recommend innovations that improve quality and effectiveness of company products

Required Qualifications

• B.S. in Mechanical or Aerospace Engineering, M.S. or Ph.D. preferred.
• 5+ years of hands‑on experience with engineering design and analysis of turbomachinery at OEM, supplier, or consumer products company
