About the Role

At Tellen, we're building secure automation tools that fundamentally change the way auditors work — freeing teams from rote tasks so they can focus on judgment where it matters. We're operating in a niche, high-trust space, solving problems no one else is tackling. We're looking for a sharp, self-motivated Full Stack Engineer to join our small, fast-moving team. You'll work across the stack — from database design to frontend experiences — shipping production-ready code that delivers real value to customers.
