About Fusion Auth

Fusion Auth is a fast-growing startup and leading provider of customer identity and access management (CIAM) software headquartered in Denver, Colorado. Our mission is to make authentication and authorization simple and secure for every developer. Our product helps businesses securely manage customer identities and access, ensuring a seamless and safe user experience for some of the largest brands in the world.

We are committed to delivering exceptional value and satisfaction to our clients through top‑notch service and support. With a great team and strong investors, we are expanding our team to help accelerate our growth and take Fusion Auth to the next level.

Fusion Auth is looking for a Senior SDR Lead to own and rebuild our outbound pipeline generation engine.

We're looking for an operator who can think strategically, execute tactically, and help establish a repeatable outbound motion targeting engineering leaders and technical buyers. You'll work directly with marketing leadership to define ICPs, refine messaging, develop account strategy, follow‑up with inbound MQLs, and execute outbound campaigns — all while carrying your own pipeline targets.

This role is both an individual contributor and a strategic partner to marketing and sales leadership. The ideal candidate combines strong outbound execution with strategic thinking, excellent cold calling skills, technical curiosity, and an ownership mentality. You love cold calling, multi‑threading accounts, selling to technical personas, building processes, experimenting with messaging, and owning results.

As Fusion Auth's outbound pipeline leader, you'll have the opportunity to shape the future of our outbound organization — documenting best practices, building playbooks, and eventually coaching future SDR hires as the team grows.
