• Strong experience in the design and development of complex catheter systems, including one or more of the following:
  • Multi-material composite catheter construction
  • Multi-lumen shaft design
  • Coil reinforcement structures
  • Torque transfer systems including braids and laser-cut hypotubes
  • Balloon integration and attachment methods
• Strong understanding of catheter materials including hypotubes, nitinol, polymer shafts, braids, coils, adhesives, and bonding processes
• Proficiency with 3D CAD software, preferably SolidWorks
• Demonstrated hands-on experience building prototypes, performing mechanical testing, and interpreting performance data
• Experience identifying and supporting appropriate catheter manufacturing processes and assembly methods
• Working knowledge of design controls, risk management, ISO 14971, ISO 13485, and 21 CFR Part 820
• Familiarity with applicable medical device standards including ISO 10555, ISO 11070, ISO 5840, ISO 25539, and related standards
• Strong analytical, problem-solving, and troubleshooting skills
• Effective verbal and written technical communication skills

Preferred Qualifications

• Experience with steerable or deflectable catheter systems
• Experience with complex multilumen shaft constructions or devices incorporating imaging, ablation, or therapeutic technologies
• Hands-on experience with catheter manufacturing processes including braiding, laser processing, bonding, reflow, tipping, and thermoforming
• Experience developing devices for structural heart, cardiovascular, or aortic applications
• Experience supporting transfer to manufacturing and production scale-up activities
• Familiarity with statistical analysis tools and engineering test method development

Skills, Knowledge, and Abilities

• Strong technical understanding of catheter design architecture and manufacturing methodologies
• Ability to work independently while managing multiple development priorities and timelines
