Senior Director, Head of Marketing

When was the last time you achieved the impossible? If that thought feels overwhelming, you might want to pause here, but if it sparks excitement, read on.

In 2015, we pioneered a “moneyball for biotech” approach, pooling projects and promising early‑stage research from academia together under one financial umbrella to reduce risk and unleash innovation. This model allows science and small teams of experts to lead the way. We build bridges to groundbreaking advancements in rare disease, and develop life‑changing medicines for patients with unmet needs as fast as humanly possible.

Together we define white space, push boundaries, and empower people to solve problems. If you're someone who defies convention, join us and work alongside some of the most respected minds in the industry. Together, we'll ask “why not?” and help reengineer the future of biopharma. At Bridge Bio, we value curiosity and experimentation—including the ethical & thoughtful use of AI to improve clarity, speed, and quality of work.

You are a seasoned rare disease commercialization leader who thrives at the intersection of science, strategy, and execution. You have led — or been a critical architect of — at least one rare disease launch, and you understand that in a small‑patient, high‑science category, every HCP interaction and every patient touchpoint matters. You know how to build a brand from the ground up, how to mobilize a field team around a clear and compelling narrative, and how to make the most of a narrow but deep opportunity.

The Senior Director, Head of Marketing will serve as the commercial brand authority for Calci (encaleret) — Bridge Bio's oral CaSR negative allosteric modulator in NDA review for Autosomal Dominant Hypocalcemia Type 1 (ADH1). This is a first‑in‑class asset targeting a chronically underserved rare endocrine population, and this role represents a defining commercial leadership opportunity. You will own the full marketing function for Calci: leading HCP marketing, patient marketing, and KOL engagement under a single integrated brand strategy.

You will report directly to the SVP, Sales & Marketing — Endocrinology and will be expected to be on‑site in both our San Francisco and Palo Alto home offices on a weekly basis.

This is not a role for someone who needs a playbook. It's a role for someone who writes one.
