• This is a Direct Hire position, up to $150k/year (no C2C or Sponsorship or 1099 or Visa Transfer)
• 3 days on site in Orange, CA
• Must have experience in the field, definitely prefer HVAC industry experience - QA of electro-mechanical products/fluid management/pump/hydraulic products
• Must be able to pick up the ball/take initiative and deluver
• need to understand quality from the perspective of customer and market needs
• Must have been part of the process from product design to release and ideally first 90 days of product launch, need to be able to take bare components or whole units. you will test for relaibility for warrenty purposes. you do verification testing and prototyping. need to have both product and process design. experience the whole process of design testing. need to know how to create the test process.
• Vacuum and recovery pumps come into play for the position, need to understand the whole connected system; their vaccum pump product will be the first project you work on

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
