Senior Principal Stent Frame Design Engineer

About the Role We are looking for an experienced Design Engineer to join our team, focused on developing self-expanding stent frames for implantable transcatheter medical devices.  In this role, you will apply expertise in stent frame design, shape memory materials, computational engineering, structural mechanics, and engineering evaluation to develop and optimize complex stent geometries. You will collaborate with cross-functional teams to translate clinical use conditions, material properties, product requirements, and manufacturing capabilities into innovative, manufacturable device designs.

This position provides an opportunity to solve complex technical challenges, develop advanced computational methods, and influence next-generation cardiovascular technologies from concept through commercialization.

Diversity is a core value  are passionate about building and sustaining an inclusive and equitable work environment for all Associates. We believe every member of our team enriches our work environment by exposing us to a broad range of perspectives to understand and engage with our customers, suppliers, and each other.

This position will be located at one of our facilities in Phoenix or Flagstaff, Arizona, with the possibility of a hybrid work arrangement. Responsibilities Lead the design and development of self-expanding stent frames and related implantable structures for transcatheter cardiovascular devices, translating design input requirements into robust design solutions while delivering against project priorities and timelines from concept through commercialization.

Develop and optimize stent frame architectures, geometries, and materials to meet device performance requirements, including but not limited to radial stiffness, flexibility, fatigue durability, deployment behavior, and manufacturability.

Apply knowledge of structural mechanics, material behavior, and manufacturing processes to guide design decisions, evaluate technical tradeoffs, and develop robust design solutions.

Develop and deliver comprehensive design packages, including detailed CAD models, parametric designs, engineering drawings, specifications, tolerance analyses, performance evaluations, and technical rationales supporting design decisions in accordance with ASME and applicable quality system requirements.

Plan, execute, and document engineering evaluations, mechanical testing, and design of experiments (DOE), to evaluate stent performance, optimize designs, and reduce technical risk.

Partner closely with Modeling & Simulation (FEA) team to evaluate stent frame behavior under representative use conditions, including compression, catheter loading, delivery, deployment, and cyclic mechanical loading, and use computational analysis results, experimental testing, and dimensional or image-based measurements to inform design decisions.

Collaborate with teams specializing in materials, manufacturing, quality, testing, suppliers, etc. to develop manufacturable stent frame designs.

Lead and participate in technical design reviews, serve as a formal technical reviewer within the quality system, and apply structured problem-solving methods.

Develop and improve computational design and engineering capabilities through automating design workflows for parametric CAD product modeling, FEA, DOE, tooling, statistical analysis, etc.

Contribute to innovation through new device concepts, hands-on prototyping, engineering evaluation methods, and intellectual property generation while providing technical guidance and mentorship to other Design Engineers.

Required Qualifications Bachelor's degree in Mechanical Engineering, Biomedical Engineering, or a related engineering discipline with a minimum of 8 years of relevant design engineering experience

Demonstrated experience in one of the following areas:

Transcatheter Stent Frame Design: hands-on experience designing and developing self-expanding or balloon-expandable stent frames, nitinol-based implantable structures, or closely related transcatheter cardiovascular devices, ORComputational Design & Engineering: experience applying computational design and engineering methods to complex mechanical structures, parametric CAD modeling (e.g., using Solidworks, Rhino/Grasshopper), computational workflow automation, and experience integrating experimental or image-based data (e.g., UCT) into engineering analyses to inform designs

Strong understanding of structural mechanics, material behavior, and mechanical performance,…
