• Perform engineering analysis including tolerance stack-ups, material selection, mechanical characterization, and performance evaluations
• Build, refine, and troubleshoot prototype devices through hands-on bench development and iterative testing
• Lead or support design verification activities including DV planning, development of test methods, protocol generation, and execution of mechanical and simulated-use testing
• Collaborate with Operations, Tooling, Quality, and Manufacturing Engineering teams to develop robust and scalable manufacturing processes
• Support Design for Manufacturability (DFM) initiatives related to catheter assembly, braiding, bonding, thermoforming, laser processing, and other specialized manufacturing techniques
• Prepare and maintain Design History File (DHF) documentation including design inputs, design outputs, risk management files, protocols, reports, and engineering change documentation
• Translate user needs, physician feedback, and clinical requirements into actionable engineering design inputs and specifications
• Participate in design reviews, technical discussions, and project planning activities to support program milestones and deliverables
• Support root cause investigations, CAPA activities, and product/process improvement initiatives
• Ensure compliance with applicable FDA regulations, ISO standards, and Aptyx Quality System requirements
• Mentor junior engineers and provide technical guidance where applicable
• Perform other duties as assigned in support of engineering and business objectives

Required Qualifications

• Bachelor's or Master's degree in Biomedical Engineering, Mechanical Engineering, or related engineering discipline
• Minimum of 3 years of medical device product development experience; 5+ years preferred
• 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
• Strong documentation discipline and attention to detail within regulated environments
• Ability to collaborate effectively within cross-functional teams including R&D, Quality, Manufacturing, Regulatory, and Program Management
• Hands-on engineering mindset with strong troubleshooting and iterative development capability
• Ability to communicate complex technical concepts clearly to both technical and non-technical audiences

Physical Demands and Work Environment

This position requires work within office, laboratory, manufacturing, and cleanroom environments. The employee must be able to:

• Sit, stand, and move throughout engineering labs and manufacturing areas
• Perform detailed hands-on prototype assembly and bench testing activities
• Use hands and fingers for fine motor assembly and measurement tasks
• Operate laboratory and test equipment safely and effectively
• Lift and move materials and equipment within safe working limits
• Communicate effectively both verbally and in writing

Reasonable accommodations may be made to enable individuals with disabilities to perform essential functions.

Measurement of Performance

• Achievement of project milestones and technical deliverables within established timelines
• Quality, completeness, and compliance of engineering and DHF documentation
• Effectiveness of prototype development, testing, and technical problem solving
• Contribution to successful product development and commercialization activities
• Collaboration and responsiveness within cross-functional project teams
• Compliance with regulatory, quality, and design control requirements
• Contribution to process improvements, innovation, and technical excellence within the engineering organization
