About The Position

We are at an inflection point. With a Series B on the horizon and a growing portfolio of partnerships with drug developers and patient advocacy groups, we need a Chief of Staff who can operate as a true right hand to the Founder and CEO — someone who runs toward complexity, brings structure to ambiguity, and holds the highest standards of craft and detail. You will own high-stakes initiatives, manage venture fundraising end-to-end alongside the CEO, and serve as a force multiplier across the leadership team. If you have thrived in fast-moving, dynamic environments and want your work to directly improve patient outcomes, this is the role for you.

Requirements

8+ years of experience, with a strong foundation in management consulting (McKinsey, BCG, Bain, or equivalent) and subsequent operating experience at a high-growth startup
Prior experience supporting or managing a fundraising process (Series A>D ideally); demonstrated understanding of investor relations and venture dynamics
Track record of operating at the intersection of strategy and execution — you are as comfortable in a boardroom as you are building a process from scratch
Experience in healthtech or biotech or track record of operating in highly complex industries
Meticulous attention to detail — you catch errors others miss and hold every output to an exceptionally high standard
Proven, demonstrable AI literacy — you actively use AI tools (beyond prompting) in your daily workflow and can lead others in doing the same
Exceptional written communication — you write with clarity, economy, and impact
Skilled at managing multiple shifting priorities without dropping the ball — you thrive in dynamic environments where the roadmap changes week to week
High emotional intelligence and leadership presence — you know when to push, when to listen, and how to build trust quickly
A collaborative, low-ego operating style — you care about outcomes, not credit
A good person. We work with some of the most marginalized populations on the planet and empathy is key
Patient-focused and motivated to have a lasting, positive impact on humanity
Comfortable in a fast-paced, often ambiguous environment with rapid change
Action-oriented and excited to build a company from the ground up
