Chief of Staff

Superlinear Partners is a family office making direct private investments in B2B services, industrials, manufacturing, and healthcare. The Executive Assistant to the CEO is at the intersection of the principal's personal life and the firm's business operations, and is one of the most trusted seats in the organization. The Role - You'll be the right-hand to the CEO across both worlds: a complex personal life (multiple residences, planes, boats, family logistics) and an active investment business (deals, events, special projects, a 30+ person team). Today, the split is roughly 70% personal / 30% business. That ratio will shift over time. This is a high-trust, high-ownership role. You'll move fast, anticipate needs before they surface, and bring an obsessive eye for detail to everything from a dinner reservation to a board offsite. You'll say no on the CEO's behalf, you'll fix things quietly, and you'll make the entire operation look effortless.
