About The Position

Sage is seeking a Chief of Staff to partner directly with its CEO, Raj Mehra, to extend his capacity and effectiveness across the company’s highest priorities. Following its recent Series C, Sage is entering a new phase of growth that requires increased focus, alignment, and operational rigor. This role marks the first Chief of Staff hire at a pivotal moment for the company. The Chief of Staff will play a crucial role in shaping how Sage scales over its next phase of growth. This is a high-impact, high-visibility role for a strategic operator who can manage ambiguity, take initiative, and is motivated by building. The Chief of Staff will act as a force multiplier; owning critical initiatives, improving how decisions are made and executed, and driving alignment across the organization. The right candidate brings sharp business judgment, operational discipline, and an entrepreneurial spirit. They are equally comfortable zooming out to influence strategy and driving execution at a detailed level. The Chief of Staff will also work in partnership with Sage’s cofounders, executive leadership team, and executive assistants. This is an individual contributor role, reporting to the CEO. The position is based in Sage's Union Square office, working in-office every Tuesday through Thursday at a minimum, aligning closely with Raj’s in-office schedule.
