Job Title: Senior Mechanical Engineer: Test Development Engineering 
Location: South Jordan, Utah (onsite)
Department: Quality Assurance As a Senior Mechanical Engineer in Test Development Engineering, you will play a critical role in the design, validation, and sustainment of precision assembly, test, and calibration equipment. You will be responsible for designing and maintaining jigs, fixtures, and metrology test systems that ensure product performance, repeatability, and compliance with quality standards. Your work will directly enable calibration traceability, measurement accuracy, and test automation across manufacturing and product validation environments. You will also manage documentation, test protocols, and calibration procedures to ensure long-term reliability and compliance of test and measurement assets.Key Responsibilities:Design and Development:Conceptualize, design, and document assembly jigs, test fixtures, and precision metrology systems to support both production and validation testing.Develop custom calibration and test instruments, including mechanical, pneumatic, and electro-mechanical assemblies for high-accuracy measurements.Integrate sensors, load cells, displacement transducers, pressure gauges, and other instrumentation into test systems to support product calibration and verification.Collaborate with cross-functional teams (Design, Manufacturing, Quality, Calibration Labs, and Contract Manufacturers) to define test requirements and system capabilities.Utilize CAD software (Creo, SolidWorks) to create detailed 3D models and drawings of mechanical systems, with GD&T applied for precision alignment and repeatability.Generate and maintain Requirement Documents, Calibration Procedures, and Test System Specifications to ensure alignment between product and test design intent.Participate in supplier design reviews and qualification of external test and calibration equipment.Testing, Validation, and Calibration:Develop and validate test procedures, calibration methods, and verification plans for measurement systems and mechanical fixtures.Ensure measurement system analysis (MSA), gage R&R, and traceability to NIST or equivalent standards in all calibration processes.Conduct statistical evaluations of test data to assess system reliability, repeatability, and reproducibility.Analyze performance results and implement design improvements to maintain precision, accuracy, and robustness under production conditions.Collaborate with electronics and software engineers to define mechanical interfaces for automated test systems and integrate sensors into data acquisition platforms.Maintenance and Troubleshooting:Diagnose and resolve issues with jigs, fixtures, or test systems, including alignment errors, sensor drift, and calibration failures.Develop preventive maintenance and recalibration schedules for all test and measurement equipment.Support production and test engineering teams by providing quick-turn mechanical solutions to test station downtime or measurement deviations.Documentation:Create comprehensive documentation for design specifications, calibration procedures, maintenance manuals, and traceability records.Maintain revision-controlled records for test system configurations, calibration certificates, and design changes.Ensure compliance with internal quality management systems and industry standards (ISO 17025, ISO 9001, or equivalent).Continuous Improvement:Identify opportunities to enhance test accuracy, throughput, and system robustness through mechanical and process improvements.Implement design-for-calibration and design-for-test principles in future product and fixture designs.Stay current with advances in precision mechanics, metrology instrumentation, and automated test system design.Participate in continuous improvement initiatives, lean design efforts, and equipment standardization programs.
