Firmware Verification/Test Engineer (Blackbox)

Title : Firmware Verification / Test Engineer (Blackbox)

Location: Burnsville, MN OR Lincoln, NE – 100% ONSITE. Preference is on local, will look at Nationals if a perfect fit

Length of Contract: 8 Months

Ideal Start: as early as 5/12 if we can get someone there

Scope: They will need figure out what test cases need to be written, write the test case and then will be running / executing the test case and then integrating them into Azure Devops.

This beltpack device contains a microphone and 3.5 aux audio path, wireless interfacing using the DECT standard, bluetooth, and an onboard screen with button and rotary controls--all tied together with an embedded linux OS software stack. The beltpack connects to an access point which sends audio over the network to another device called a matrix. The matrix mixes together desired audio sources and sends the audio to the beltpacks or other RTS products or non-RTS destinations on the network.

Candidates will be evaluated for effectiveness in verifying the above system. Ideal candidates will have an understanding of audio and RF fundamentals and have a history of testing each from a functional perspective. This is a position in the software team; however, the position is responsible for leading verification activities. This includes verifying the functions at the system level according to the system requirements and also providing feedback and authoring changes against the requirements.
