System Design Engineer

The System Design Engineer designs and engineers complex electromechanical devices. This role requires a passion for technology product development, particularly in consumer electronics, and experience collaborating with cross-disciplinary engineering teams. The ideal candidate understands human-centered design and brings strong technical problem-solving, communication, leadership, and interpersonal skills. This role also supports the manufacturing processes for our established line of electromechanical sensor systems (producing ~100,000 units annually).

They should also be high-energy, self-motivated, proactive, and comfortable working in a fast-paced, evolving environment.

• Design and develop mechanical components and assemblies for including wearable IoT devices, manufacturing equipment, and more using Solid Works
• 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

• Monitor manufacturing activities for electromechanical sensor systems, providing engineering support to troubleshoot and resolve production issues promptly.
• Maintain and troubleshoot electromechanical manufacturing fixtures and test equipment, utilizing both hands-on and remote methods.
• Analyze production data to identify trends, lead root cause analysis (RCA) efforts for failures, and proactively support manufacturing sites to maximize up-time.
• Interface with internal teams and external suppliers to address manufacturing-related concerns that arise.
• Perform annual and as-needed service visits for equipment installation and maintenance. Requires ~5% travel, both domestic and Mexico.

• 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

• BS in Mechanical Engineering, Systems Engineering, or closely related field
• Proficiency in Solid Works for 3D modeling, assemblies, and engineering drawings
• Understanding of GD&T, tolerance stack-up analysis and design-for-manufacture principles
• Hands-on prototyping experience: 3D printing, manual machining, and other fabrication methods
• Analog and digital signal acquisition and measurement experience
