Job description

About The Role

We are looking for a Modeling & Simulation Scientist to join our team. In this role you will use Computational Fluid Dynamics (CFD) expertise to provide support for design, development, and optimization of medical devices. This role offers a unique opportunity to model cardiovascular hemodynamics, supporting product innovation, design iteration, and regulatory submissions. Working closely with cross-functional teams, you will use simulation-driven insights to predict device performance, identify worst-case scenarios, and accelerate product development through virtual testing. The successful candidate will perform CFD analyses by applying principles of fluid mechanics, material behavior, and medical device durability to solve complex engineering challenges and advance patient care.

This position will be located at our facility in either Flagstaff or Phoenix, Arizona, with the possibility of a hybrid work arrangement.

Responsibilities

• Provide analytical support in the areas of medical product design, optimization and new product development.
• Perform CFD/FSI modeling of transient flow, species transport, porous jumps, multiphase flow, mass transport and heat transfer analysis to support accelerated product design and evaluation.
• Perform other analytical procedures that will assist in the application, design and manufacture of medical products.
• Advance the use of data driven modeling using AI/ML and PINNs techniques.
• Develop techniques to combine data driven modeling with physics-based modeling.
• Verify and validate computational analyses.
• Support continuous improvement of modeling workflows, tools, and best practices.
• Review and provide feedback on modeling approaches and analyses performed by peers.
• Document and communicate results through technical reports and presentations.

Required Qualifications

• Master of Science degree in mechanical or biomedical engineering with a minimum of 5 years’ experience in computational fluid dynamics analysis
• Experience in computational fluid dynamics software, specifically analysis in Fluent, Star CCM , COMSOL or similar with related pre- and post-processing software
• Experience in cardiovascular hemodynamics
• Programming or scripting experience (Python, MATLAB, or similar) for automation and data processing
• Experience creating user-defined functions for modeling; experience with AI/ML
• Advanced experience in solid modeling, specifically SolidWorks
• Proven ability to embrace new concepts and learn quickly
• Ability to independently manage multiple simulation projects, solve complex modeling challenges, and collaborate effectively across multidisciplinary teams
• Excellent communication and technical documentation skills
• Ability to travel up to 5%

Desired Qualifications

• Doctoral degree in mechanical or biomedical engineering
• Experience with verification and validation of computational models, and with techniques such as Particle Image Velocimetry (PIV)
• Experience with thrombosis modeling
