Systems Design Engineer

About the role

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
