Needle design & engineering
* design curved suturing needles (taper point, reverse cutting, specialty profiles).
* define key geometric features: tip radius, facet angles, edge symmetry, curvature.
* balance penetration force, drag, and edge durability for clinical use cases.
* convert surgeon and clinical feedback into measurable engineering requirements.
* define and support test methods for penetration force, drag, and edge retention.
materials & metallurgy
* select and specify metallic materials (e.g., stainless steel needle alloys).
* define cold working, annealing, and heat‐treatment strategies to achieve target mechanical properties.
* control hardness, ductility, toughness, and grain structure for performance and manufacturability.
* collaborate with material suppliers to establish performance‐based specifications.
manufacturing technology & industrialization
* develop needle designs compatible with high‐volume manufacturing.
* 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.
* partner with manufacturing engineering to improve capability, yield, and consistency.
* support automation and reduction of operator‐dependent variability.
professional experience
* 8–12+ years of experience in surgical needle design, development, or manufacturing.
* proven background supporting high‐volume precision manufacturing environments.
* advanced english
* willingness to travel to the usa
technical expertise
* strong understanding of needle geometry, sharpness mechanics, and tissue interaction.
* hands‐on experience working with metallic materials and heat‐treatment processes.
industry knowledge
* familiarity with regulated medical device development environments and applicable standards.
