At Inspira, you'll work directly with the founders to identify the highest-leverage opportunities across our business, design the solutions, and build them yourself. No handoff. No waiting for someone else to execute. You move, it moves. The business is at an inflection point. We have strong demand, a proven model, and a global network of counselors helping students get into the world's best schools. What we need now is the operational infrastructure to match our ambition — and the person to build it. That's this role. The Work This is a player-coach role. You'll lead teams and develop people while staying close enough to the work to know when something isn't right — and fix it yourself when it needs to be fixed. We're not looking for someone who manages from a distance. We're looking for someone who sets the standard by living it. Student-Counselor Matching & Customer Operations Own t

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.
