About the Role

At Tellen, we’re building secure automation tools that fundamentally change how auditors work—freeing teams from rote tasks so they can focus on judgment where it matters. We’re solving hard problems in a niche, high-trust space. We’re looking for a technical leader who can own both product execution and engineering quality. At Tellen, your ‘team’ is a set of AI agents. You’ll manage and coordinate them, drive product development from the ground up, and ensure what ships is well-designed, robust, and valuable to our customers.
