About The Position

The Chan Zuckerberg Initiative was founded in 2015 by Priscilla Chan and Mark Zuckerberg to harness the power of technology to pursue some of society’s most ambitious goals — from curing or preventing all disease to transforming how students learn. At CZI, you’ll join a deeply collaborative, mission-driven community where your work helps drive breakthroughs across our flagship nonprofit organizations, Biohub and Learning Commons. Whether enabling scientific breakthroughs via open science and AI-powered biology or strengthening the tools teachers and students rely on every day, your contributions help turn bold ideas into real-world impact. Our teams operate at the intersection of innovation and scale, building the infrastructure, partnerships, and capabilities that allow scientists, educators, and innovators to tackle some of the most complex challenges of our time — and to do so with urgency, integrity, and optimism. The Biohub Communications team shapes how the world understands our science, our people, and our mission. We partner with researchers, engineers, and leaders across Biohub to tell stories that make cutting-edge science accessible, inspire collaboration, and highlight the breakthroughs that are advancing our understanding of biology and disease. Our team brings together expertise in media relations, brand, content, creative, digital communications, and social media to engage audiences ranging from the global scientific community to policymakers, partners, and the public. We believe the most impactful communications are grounded in curiosity, creativity, and scientific integrity—and we use storytelling to build trust, spark conversation, and amplify the discoveries that have the potential to transform human health. As part of the Marketing & Communications organization, you'll collaborate with a talented, mission-driven team that values experimentation, thoughtful strategy, and bold ideas. Together, we're building a distinctive voice for Biohub that reflects the ambition of our science and the people behind it. The Biohub social team is looking for a creative and collaborative Social Media Manager to shape how Biohub’s mission and story shows up across social media. In this role, you’ll own the strategy and management of Biohub’s social channels — figuring out what belongs on which channel, for which audience, and why — while also staying close to the execution and day-to-day rhythm of running our channels. This role covers both moments that need a specific, campaign-style push (launches, major announcements, events) and the always-on work of building a steady cadence of social content that keeps our community engaged and excited about Biohub’s work in frontier AI and biology. The ideal candidate is a low-ego collaborator, genuinely curious, brings forth a positive and engaged mindset, and has a bias for action and finding solutions. This role reports to the head of social and will be a part of the broader Marketing and Comms team.
