Head of Marketing

At Weave, our mission is to evolve how therapeutic knowledge is captured, transformed, and communicated throughout drug development. We do this by equipping human experts with AI instruments to enable drugs to be brought to patients as rapidly, safely, and inexpensively as possible.

The Weave Platform streamlines regulatory workflows from start to finish by intelligently, creatively, and effectively infusing every step with AI. Together with our customers, Weave is designing and building the AI workbench for the entire therapeutic lifecycle.

Reporting directly to Chief Executive Officer, the Head of Marketing will serve as a key member of the leadership team, responsible for driving all marketing strategy and pipeline impact. This operationally minded marketing leader will define and execute Weave Bio’s full-stack marketing function, ensuring scalable processes, predictable performance, and strong positioning and demand generation discipline. This leader will build and mentor a growing team, refine segmentation, personas, and channel strategy, and establish the foundation for sustained growth as Weave Bio expands globally.

Drive the company through its next phase of growth by refining segmentation, ICPs, and persona strategy, optimizing mid‑market and enterprise engagement, and establishing integrated campaigns that support predictable, sustained growth.
• Complex SaaS Marketing: Bring experience managing multi‑channel marketing programs for complex, AI‑and‑data‑driven software products, ranging from lighter‑touch digital motions to high‑consideration enterprise initiatives.

• Early‑Stage SaaS Growth Environment: Operate effectively in a fast‑paced, venture‑backed environment with high growth expectations and limited layers of structure. Collaborate with the CEO, CCO, and investors to shape marketing strategy, narrative, and positioning, ensuring Weave Bio’s continued leadership in AI‑driven regulatory technology. Bring a bias toward execution, a focus on measurable impact, and an ability to scale systems and people as the company grows.
