Enterprise Customer Success Manager

Enterprise Customer Success Manager

About the role
Distribution keeps the world running. It gets pipes, parts, and products where they need to go. Yet many distributors still sell the way they did 20 years ago. Proton is changing that. We’re the AI-powered industry cloud for B2B distributors, bringing together CRM, PIM, Quote and Order Entry automation, Pronto, and AI agents in one platform.

Our best CSMs aren’t software experts first. They’re curious people who love figuring out how a business really works while also being able to. They ask “why” until they get to the real answer. They talk with customers about growth, margins, and how reps spend their day, not just about features. When there’s no easy answer, they don’t stop. They rally the right people at Proton and find a way forward.

As an Enterprise Customer Success Manager, you’ll own a ~$2.5M ARR book of enterprise and mid-market customers. One day you might be in a CEO’s office helping them craft their AI strategy. The next, you might be riding along with a rep to see why a workflow isn’t sticking. The work will stretch you. It’s also deeply rewarding, because you’ll see your impact show up in your customers’ growth.

This is a hybrid role based in the greater Boston area, with 10+ customer visits a year.
