Senior Design Engineer

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.
