The Role You'll be the face of our technology in every room that matters, proving, not just pitching, that our switch is the answer. From presales qualification to live demos to design reviews, you own the client conversation end to end, at our office or theirs, hardware in hand. You build the test setups, run the demos, and dig into the failure analysis when something breaks, because credibility here is earned, not claimed. And everything you learn feeds straight back into product, engineering, and sales.
