We're looking for an engineer at heart who sees quality as a lever to build better products-not just test them. This role is for someone who thrives at the intersection of hardware, firmware, and software, with a deep understanding of how these systems interact-and where they can fail.

You bring a strong foundation in electro-mechanical systems, a hands-on mindset, and a passion for getting involved early to influence design decisions with data. You're naturally curious, analytical, and relentless in pursuing root cause. You partner effectively across teams and bring sound judgment to balance performance, reliability, and compliance at scale.

What You'll Do

Drive Quality in Design

• Partner with engineering teams to embed quality into every phase of product development across mechanical, electrical, firmware, and software systems
• Perform engineering analyses (e.g., fluid dynamics, heat transfer, load calculations) to validate performance targets such as flow rate and vacuum levels
• Build and test prototypes to validate real-world performance early in the development cycle
• Develop product specifications and assess process capability (Cpk, SPC) to ensure consistent, scalable quality
  
  

Own Verification & Validation (V&V)

• Design and execute comprehensive test plans to validate performance, usability, and safety requirements
• Create test environments that simulate real-world operating conditions
• Troubleshoot and resolve design issues through structured testing and root cause analysis
• Ensure full traceability from requirements through validation, including DFMEA integration
  
  

Collaborate & Influence

• Work cross-functionally with design, engineering, and manufacturing teams to deliver high-quality outcomes
• Provide meaningful input during design reviews-your perspective will directly shape the final product
• Support manufacturing ramp and resolve issues observed in production or the field
• Ensure compliance with global regulatory and safety standards (EPA, IECEx, ATEX, etc.)
  
  

Qualifications

• Bachelor's degree in Mechanical, Electrical, Electro-Mechanical Engineering, or a related field (Master's preferred)
• 10 years of progressive Quality Engineering/Assurance experience in a product-based environment involving hardware, firmware, and software
• Proven experience developing test environments, test procedures, verification plans, and conducting failure analysis
• Strong working knowledge of ISO 9001:2015, particularly in design and development
• Hands-on experience with verification and validation of electro-mechanical products
• Proficiency with CAD and simulation tools (SolidWorks, AutoCAD, Revit, or similar)
• Experience working with overseas ODM/OEM partners
• Excellent analytical, problem-solving, and documentation skills
• Strong communication skills with the ability to influence cross-functional teams
• Ability to manage multiple priorities and deliver on timelines
