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. 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 

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
