Role Description This is not a strategy role. It is not a coordination role. It is a get-in-and-do-it role for someone who wants real ownership, moves fast, and finds energy in problems that have never been solved before. You will own the important projects that currently have no clear owner. You will work directly with leadership on high-priority initiatives that are undefined by design, because they are new. Each project starts from scratch: new domain, new constraints, no template. You will figure out what the right question is, get smart fast, and drive it all the way to done. The best version of this person is someone who would rather build the map than wait for one. You do the research, write the recommendations, make the call, and keep moving. If you are looking for a role where you can put your head down and execute on work that matters, this is it. This role is best suited for those energized by fast-paced environments, excited to build in a high-growth setting, and deeply motivated by our mission. If you’re looking for meaningful challenges, dynamic work, and the opportunity to make a real impact — we’d love to meet you. Key Responsibilities - Own projects end-to-end. From scoping the actual problem to delivering a finished outcome. These initiatives are high-priority and undefined by design. - Do the work. Research new domains from scratch, structure the problem, produce real outputs: recommendations, plans, frameworks. Not summaries of what others should do. - Write clearly and drive alignment. Turn ambiguous situations into a point of view leadership can act on. Keep stakeholders informed and bring the right people in at the right time. - Make decisions and move. You will not have perfect information. You will make the call anyway and adjust as needed. - Work across functions. Operations, product, clinical, legal, finance. You go where the project needs you, not where the org chart points. - Drive multi-million dollar initiatives from concept through execution, staying accountable for outcomes at every stage. Qualifications - Doer first. You do not delegate the hard parts. You go deep, get your hands dirty, and produce work product others can act on. - Moves fast under uncertainty. Comfortable without a playbook. Makes good calls with incomplete information and adjusts quickly when things change. - Writes well. Clear, structured, direct. You can take a complex situation and turn it into something people can act on. - Strong judgment. Knows which details matter and which do not. Spends time accordingly. - High ownership. Full accountability for outcomes, not just effort. Takes initiative without being asked. - Mission-driven. Genuinely believes preventive healthcare is one of the most important problems to get right and wants their work to be part of making it real. Requirements - 7+ years of experience with a track record of owning hard, ambiguous problems and driving them to completion. - Has built something from scratch. A team, product, process, or business. Understands what zero-to-one actually requires. - Has managed complex, multi-stakeholder projects where they were the one holding the thread together. - Can point to specific examples of turning a vague, undefined problem into a clear path forward and then executing it. - Strong written communication. You can show your work, and it holds up. Benefits - Base Salary: $180,000 - $210,000 - Stock options - Comprehensive health, dental, and vision plans for you and your family - Wellness and commuter benefits - Competitive vacation policy - A culture that emphasizes learning - Professional development budget for continued learning - Opportunity to directly impact our mission of saving lives through early cancer detection
