For over 20 years, Smartsheet has empowered teams to manage work seamlessly and scale solutions smarter. Now, in our most ambitious chapter yet, we are uniting human teams with AI agents. By orchestrating the work agents do best, automating manual tasks and uncovering insights at scale, we create the space for people to focus on what truly matters: judgment, creativity, and big thinking. That is magic at work, and it’s what we show up for every day. AI is reshaping what product security can accomplish, both as a target and as a tool. We're looking for a Principal Security Engineer to own the highest-leverage application security work at Smartsheet: leading threat modeling and product security reviews across a modern SaaS platform used by millions of customers, serving as the team's technical authority on AI security risk, and setting the technical standard for application security practice across the engineering organization.

You will partner closely with our Design Director as a trusted right hand, owning the hardest and most ambiguous problems, setting the quality bar, and helping decisions move so design is never the bottleneck. Two things sit at the center of this role: designing for AI-native experiences, and rethinking how design itself gets done in AI-first workflows. We are fully immersed in both, and this role has a real hand in shaping where they go. We want someone genuinely eager to learn, test, and experiment here, but with the judgment to tell where AI raises the quality of the work and where it just adds noise. The aim is to use AI where it genuinely makes the work better, not to adopt it for its own sake.

You can hold “this is hard and might not work” and “let’s do it anyway, here’s how” in the same breath. You lead through craft and influence rather than authority, you take a vague problem and give it shape, you bring strong opinions but invite better ones, and you raise risks early and honestly. You lift the people around you by example, and the whole team’s work gets sharper because you are on it. What
