Who We Are

Osanni Bio is a development-stage therapeutics platform, headquartered in San Francisco, California. We are creative and agile innovators, relentlessly curious about finding new ways to target the biology behind diseases with the greatest unmet need and determined to do something about it.

Who We Are

Osanni Bio is a development-stage therapeutics platform, headquartered in San Francisco, California. We are creative and agile innovators, relentlessly curious about finding new ways to target the biology behind diseases with the greatest unmet need and determined to do something about it. At the center of Osanni is its innovation engine, which is optimized for discovering new scientific insights, designing novel drug concepts, and efficiently advancing programs to a meaningful proof-of-concept. Once a program is sufficiently de-risked, it graduates into its ecosystem of affiliate companies, which are equipped with the dedicated focus, specialized talent and support necessary to scale. Osanni's architecture marries the scientific depth and operational power of a centralized platform with the speed, agility and accountability of independent companies. The result: an opportunity to create and deliver more transformative medicines. We hold patients and the physicians who care for them as our North Star. It guides our purpose, sharpens our decision-making, and defines our impact. Osanni is currently advancing programs in ophthalmology, cardiology and beyond. We are building a highly skilled team, passionate about having an impact on human health. Be part of creating an organization where people enjoy their work and their colleagues, are valued for their individuality, and can't imagine working anywhere else.

Our Values

Osanni is guided by three core values: Integrity + Impact, because we give a hoot; Agility + Accountability, so we swoop and soar; and Collaboration + Connection, to be one Osanni Flock. Together, they shape how our team shows up for patients, for each other, and for the mission.

• Build each calendar around the executive's preferred meeting formats and rhythms, including whether a request warrants 30, 45, or 60 minutes; a call versus video versus in-person; and when travel or commute schedules can or cannot accommodate calls

• Support the VP Legal with document management, signature routing, and tracking of contracts and corporate records

Events & Culture

Confidentiality & Ways of Working

• Handle highly confidential corporate, financial, legal, and personnel information with discretion and sound judgment

• 8+ years of experience as a senior-level Executive Assistant supporting CEO and other C-suite executives, including experience supporting multiple executives simultaneously in a fast-paced, high-growth environment


• Experience coordinating Board of Directors meetings and interacting with board members, investors, and outside counsel


• High emotional intelligence and strong relationship-building instincts, with a demonstrated ability to earn executives' trust, understand their priorities, and act as a calm, professional “gatekeeper”


• Advanced proficiency with Microsoft Office and collaboration tools such as Google Workspace, Zoom, Slack, and DocuSign


• Exceptional organizational skills and attention to detail, with the ability to manage complex calendars and competing priorities


• Excellent written and verbal communication skills, with a professional and approachable presence at all levels
