Senior Field Systems Engineer

As a Senior Field Systems Engineer at Alliance Laundry Systems you will serve as the tip of the spear for diagnosing and resolving the most complex intermittent and high-impact issues affecting our laundry machines deployed at customer sites around the world. Working as part of a specialized rapid-response team of electrical and firmware engineers you will travel to customer facilities domestically and internationally to capture debug data deploy diagnostic firmware and gather the evidence needed to reproduce issues in our Ripon WI lab. You will play a critical role in investigating complex intermittent and difficult-to-reproduce issues spanning embedded firmware subsystem interactions and communications between edge machines IoT gateways and connected peripherals. Your findings will directly drive the development of production firmware patches that protect our brand delight our customers and keep our machines running at peak performance
