Responsibilities

Design and develop mechanical components and assemblies for including wearable IoT devices, manufacturing equipment, and more using SolidWorks
Support hardware design from concept and prototyping through design-for-manufacture, with an eye toward size, weight, and performance constraints
Isolate and iterate on component/feature designs with a constant eye toward system integration
Conduct analyses including mechanical (e.g. stress and tolerance stack-up) and design risks (e.g. failure modes)
Work with rapid prototyping (3D printing, CNC) and manual fabrication to iterate on designs quickly
Create and maintain engineering drawings, and BOM updates
Support integration of mechanical, electrical, and firmware subsystems into cohesive products
Assist in developing and executing verification and validation test plans and procedures
Collect, analyze, and document test data against functional and performance specifications
Identify and troubleshoot mechanical and system-level issues during bring-up and field testing
Develop and execute verification and validation test plans covering functional, environmental, and durability requirements
Design and execute structured data collection protocols in lab and field environments
Set up and operate data acquisition systems (DAQ, oscilloscope, serial logging) to capture outputs across test conditions
Analyze and interpret collected datasets to assess system performance, identify anomalies, and support design decisions
Maintain complete and current project documentation in accordance with Simbex's Quality Management System
Prepare engineering analyses and present findings to cross-functional teams
Lead and support design reviews for production releases
