Who We Are: At Bandwidth , we shape how the world connects. We're the global communications software company and Tier 1 network operator with global reach. The voice, messaging, and emergency services infrastructure behind the brands and apps you use every day. Because we own the network we build on, the problems you'll solve here are bigger, more complex, and more impactful. And as communications shifts to AI, we're the infrastructure layer making it possible. We call ourselves BANDmates because building something this big takes collaboration, different perspectives, and the freedom to bring your authentic self to the table.

Ready to build what's next? #JoinTheBand What We Are Looking For: Bandwidth is looking for a Sales Account Manager to take over an established book of about 350 SMB customers, worth roughly $8MM in annual recurring revenue. Half the job is protecting what we have: keeping customers healthy, responsive, and confident in Bandwidth. The other half is finding where they could do more with us. That means moving smaller accounts upmarket and winning traffic that large customers are still sending to competitors. Your success is measured on the performance of your book, so judging where to spend your time matters nearly as much as how you sell. What You'll Do: Take ownership of an existing book of ~350 SMB accounts, roughly $8MM ARR, as the primary point of contact. Use account data (spend trends, product mix, and usage volume) to decide which accounts need attention, which have room to grow, and which are at risk. Protect and grow the total revenue of your book. Retain existing spend, catch risk early, and expand where there's opportunity. Move customers upmarket through product expansion and winning a larger share of wallet from customers who use multiple providers. Build relationships with several contacts at each key account, from technical stakeholders to business decision-makers. Learn each custome
