Nelly is building AI-powered technology to automate administrative workflows for medical practices, reducing paperwork and enabling better patient care.
We’re looking for a highly ambitious product person to own Nelly’s Billing Agent – our core AI product that automates consultation documentation and billing for German practices and directly drives practice automation & revenue. This role is for a top-tier, high-agency PM who wants full ownership: from user discovery in the practice to AI design, launch, and commercial impact.
About Nelly
We are building the AI-Driven Financial Operating System for European healthcare, solving the biggest challenges for patients and practices. We create what no bank or software platform can handle. Our all-in-one platform transforms chaotic administrative processes into intelligent, automated workflows, from patient care to billing to next-generation payments. Because we truly believe: healthcare should be less about paperwork and more about people.
Why? Because Europe is facing a massive shortage of medical professionals. And if we don't rethink the way practices work, the system won't be able to keep up. With our Series B funding of over €50 million from world-class investors, we are turning our vision into reality.
What to expect: We work with the best team, which is why we give everything together every day. We believe in Talent Density, because exceptional people make everyone around them better. At Nelly, we move fast and expect everyone to keep up. Stagnation isn’t an option, which is why we invest heavily in growth. AI isn't a nice-to-have at Nelly. We expect you to use it every day and give you everything you need to do so. You get trust and ownership and we expect you to speak up, even when it's uncomfortable.
Joining us, you will
Own strategy & roadmap for Billing Agent: translate global product strategy and business goals into a clear, outcome-driven roadmap that maximizes practice time savings and revenue, while building compounding products with other automation teams at Nelly
Own the product lifecycle from discovery to launch: synthesize customer feedback, data, and market & technology trends into prioritized decisions that balance quick wins with strategic bets
Sharpen the core Billing Agent experience while running new bets like a high-intensity PMF lab → form hypotheses, ship, measure, iterate fast, and make hard trade-offs between scope, speed, and quality
Visit practices and work on-site with dentists and dental assistants (ZFAs/ZMVs) to deeply understand workflows and build effective vertical AI
Co-build AI experiences with engineering & design —shaping our agentic product experience. You'll define data plans, metrics, and evaluation setups (usage + agent quality) to measure impact and deliver world-class user experience in both software and service
Drive decisions with GTM & finance on pricing, rollout, expansion (vertical & geo), and commercial success through precise communication
What you'll bring
Note: If you don't meet all the criteria, we still encourage you to apply and make the case for why you'd be a great fit. If you're exceptional talent, we're happy to adapt.
