Test Automation Engineer

•NI VeriStand to Python Migration (2 openings)

Location:

Kalamazoo, MI 100% onsite. Overview Client is a global medical device manufacturer. Their Acute Care R&D group develops connected electromechanical patient-support platforms (hospital beds and stretchers) with embedded firmware, sensing, actuation, and network connectivity. Verification runs on custom Hardware-in-the-Loop (HIL) benches built on National Instruments PXI hardware. The client is consolidating verification tooling onto a single Python-based test framework. This role migrates the existing NI VeriStand test asset library into that framework preserving functional equivalence, test coverage, and verification traceability. Analysis & reverse engineering Analyze the existing VeriStand library: system definition files, Real-Time Sequences, stimulus profiles, workspace configurations, custom devices and document functional intent, signal mapping, and coverage of each test Reconstruct test intent where documentation is thin or original authors are unavailable Produce a migration inventory and sequencing plan covering dependencies, complexity, and priority Migration & development Port VeriStand test logic into the Python framework, maintaining functional equivalence with the legacy implementation Build and extend Python hardware-abstraction layers over the NI stack

•nidaqmx (DAQ, analog/digital I/O), nixnet (CAN/CAN FD), pyvisa (instrument and serial control) and over PXI chassis and real-time targets Implement reusable fixtures, drivers, and utilities so the migrated suite is maintainable, not a one-for-one transliteration Integrate migrated tests into version control and automated execution Verification of the migration Design and execute an equivalence strategy: run legacy VeriStand and migrated Python tests against the same device under test and reconcile results Investigate discrepancies, distinguishing genuine defects from timing, resolution, or signal-conditioning differences between environments Document equivalence evidence to a standard suitable for design-control review Bench & hardware work Bring up and maintain HIL benches: PXI chassis, NI modules, signal conditioning, wiring harnesses, load banks, simulated sensors and actuators Debug at signal level with oscilloscopes, logic analyzers, multimeters, protocol analyzers Support fault-insertion and boundary-condition testing on electromechanical subsystems Documentation & quality Maintain traceability from migrated tests to source requirements and test protocols Support test-tool validation and produce documentation consistent with design-control and DHF expectations Participate in peer code review, protocol review, and defect triage 5+ years embedded systems, firmware, or system-level test engineering on physical hardware NI VeriStand hands-on: system definition (.nivssdf), Real-Time Sequences (.nivsseq), stimulus profiles, workspace/screen configuration, custom devices; deploying to NI real-time targets NI hardware: PXI/PXIe chassis, real-time controllers, DAQ modules, signal conditioning; configuration in
