We are seeking an experienced Director of Sales Engineering to build and lead Mattermost’s global technical presales team.

Are you a technical presales leader who has built a team that wins the technical decision, and wants to do it for customers who protect national security and critical infrastructure? Do you want to own how a global team of Sales Engineers demonstrates, evaluates, and proves a platform that runs where other collaboration tools cannot, from classified networks to the tactical edge?
