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.
Responsibilities:
Mechanical Design & Development
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
System Integration & Testing
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
Data Collection
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
Manufacturing Process Support
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.
Documentation & Process
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
Required Qualifications:
BS in Mechanical Engineering, Systems Engineering, or closely related field
Proficiency in SolidWorks 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
Electrical fundamentals including wiring and simple schematic interpretation
Familiarity with verification and validation processes, test plan development, and documentation
Strong written and verbal communication skills; comfortable presenting to cross-functional teams
Detail-oriented, organized, and able to manage multiple tasks in a fast-paced environment
Preferred Qualifications:
Experience with wearable, consumer electronics, or medical device product development
Exposure to IoT hardware: enclosure design for PCBs, connectors and cable routing
Familiarity with Agile and stage-gate product development processes
SQL and Python script proficiency and understanding
