What You'll Do

Design and develop mechanical components and assemblies for HVAC and environmental monitoring sensors, including pressure transducers, differential pressure sensors, flow sensors, and IAQ/IEQ devices.
Create detailed CAD models, drawings, GD&T, material specifications, and tolerance analyses optimized for accuracy and manufacturability.
Support FEA and thermal analysis to validate mechanical robustness under HVAC-relevant conditions, including airflow, vibration, humidity, and thermal drift.
Support rapid prototyping for complex products.
Support and lead environmental qualification and reliability testing, including pressure cycling, humidity/condensation testing, thermal shock, and leak testing.
Optimize sensor mechanical interfaces for easy installation in air ducts, cleanrooms, mechanical rooms, and building automation systems.
Partner with Electrical, Firmware, Test Engineering, and Manufacturing teams on sensor integration and verification.
Support VAVE, cost reduction, and design improvements across the product lifecycle.
Contribute to NPI and sustaining engineering activities by solving technical problems, documenting design decisions, and supporting product improvements.
