Collaborate with manufacturing, supply chain, and suppliers to optimize designs for manufacturability and cost.
Drive continuous improvement through innovative design methods and emerging technologies.
Mentor junior engineers and contribute to team development and best practices.
Lead or support technical research and contribute to continuous process improvement activities

Strong proficiency with CAD tools (e.g. Creo)
Deep understanding of precision mechanical design principles, ASME Y14.5-2018 GD&T, and tolerance stack-ups
Experience designing components for optical systems such as lenses, lasers, sensors, and imaging assemblies.
Hands-on experience with prototyping, metrology, testing, and verification of opto-mechanical assemblies.

Qualifications We Prefer:

Knowledge of thermal management, material science, adhesives, and mounting techniques used in optical systems.
Excellent communication and documentation skills.
