About the role.
As a Principal Solutions Architect at Solo.Io, you’ll be responsible for delivering technical projects that ensure our customers get the maximum value out of our offerings. While product onboarding and adoption is a core focus, responsibilities include help with migrations, feature adoption and any technical problem whose scope is larger than what can reasonably be worked through a support ticket. Our customers are some of the most knowledgeable platform engineers and software developers in the world, and your job is to work with them on how to best architect solutions using Solo products.
