Senior Design Engineer – Surgical Suture Needles

Corza Medical is dedicated to providing exceptional products and services to surgical providers. The Senior Design Engineer – Surgical Suture Needles will focus on the design and development of high-performance suturing needles, ensuring they meet clinical performance standards through careful material selection and manufacturing processes.

Responsibilities:

• Design and develop curved suturing needles including taper point, reverse cutting, and specialty profiles
• Define critical geometric features such as tip radius, facet angles, edge symmetry, and curvature control
• Balance penetration force, drag, and edge durability across intended clinical use cases
• Translate clinical and surgeon feedback into measurable engineering requirements
• Define and support test methods for penetration force, drag, and edge retention
• Select and specify metallic materials used in surgical needles (e.g., stainless steel alloys)
• Define cold working, annealing, and heat treatment strategies to achieve target mechanical properties
• Control hardness, ductility, toughness, and grain structure to optimize performance and manufacturability
• Collaborate with material suppliers to establish performance-based material specifications
• Develop needle designs compatible with high-volume manufacturing processes
• Support and optimize forming, stamping, grinding, and edge creation processes
• Define electropolishing, passivation, and surface finishing requirements
• Support application of silicone or friction-reduction coatings where applicable
• Partner with manufacturing engineering to improve process capability, yield, and consistency
• Support automation and reduction of operator-dependent variability
• Work closely with Quality, Manufacturing, Supply Chain, and Regulatory teams
• Support technology transfer from development to production
• Provide technical input for risk analysis, design reviews, and continuous improvement efforts

Requirements:

• 8–12+ years of experience in surgical needle design, development, or manufacturing
• Strong understanding of needle geometry, sharpness mechanics, and tissue interaction
• Hands-on experience with metallic materials and heat treatment processes
• Experience supporting high-volume precision manufacturing
• Familiarity with regulated medical device development environments
• Bachelor's degree in Mechanical Engineering, Materials Science, Metallurgy, or related discipline
• Regular travel to our Tijuana, Mexico facility monthly
