 * Knowledge of global compliance standards for industrial laser products and electro-optical safety (IEC/FDA laser classes, CE, UL).

## Description

We are seeking a high-caliber Senior Mechanical Engineer to lead the design and development of next-generation industrial instrumentation, precision gauges, and advanced electro-optical measurement systems. You will be responsible for creating robust mechanical architectures that protect and optimize delicate optical paths in harsh industrial environments., * Optomechanical & Precision Design: Lead the mechanical architecture and detailed design of electro-optical instruments, laser-based gauges, sensor housings, and precision lens/mirror mounting fixtures.

 * CAD & Alignment Modeling: Build robust, parametric 3D models and precise 2D engineering drawings using SolidWorks. Design stable mechanisms to support precise optical alignment and minimize stray light.
 * Thermal & Structural Stability: Conduct rigorous Finite Element Analysis (FEA) to ensure micron-level structural stability, managing thermal expansion (CTE matching) to prevent optical misalignment under varying industrial temperatures.
 * Ruggedization & Environmental Protection: Design sealed enclosures incorporating ingress protection (IP ratings), and shock/vibration isolation without compromising optical window integrity.
 * Global Collaboration: Participate in and lead design reviews with global engineering teams, presenting technical data, optical-mechanical tolerances, and design choices fluently in English.
 * DFM & Supplier Alignment: Optimize designs for precision CNC machining, specialized surface coatings (anodizing, anti-reflective treatments), and die casting. Work closely with precision optical and mechanical suppliers to resolve tooling anomalies.
