About Ostro At Ostro, our mission is to help millions of people live healthier lives by being the missing, caring link between those who make medicines, treatments, and diagnostics, and those who take them. We create personalized healthcare journeys that boost engagement and drive improved value for consumers, HCPs, and life sciences brands.

About The Role At Ostro, we are transforming how life sciences connect with the people who need their innovations most. Every day, we help millions live healthier lives by bridging the gap between those who make medicines, treatments, and diagnostics — and those who take them. Our patent-pending AI technology powers personalized healthcare journeys that make access to trusted information as seamless and intuitive as the best consumer experiences. As the leader in AI-powered omnichannel engagement for life sciences, Ostro is trusted by a majority of the world’s top 20 pharmaceutical companies. Our intelligent platform orchestrates compliant, personalized interactions across web, email, SMS, and emerging channels — creating a unified intelligence layer that drives meaningful behavior change and better health outcomes. We are not your typical life sciences company. Our team brings together experts from leading healthcare and life sciences organizations — including McKinsey, OptimizeRx, Doximity, Klick, Real Chemistry, and Publicis Health — alongside product and engineering talent from some of the world’s most innovative technology companies like Amazon, Google, YouTube, Microsoft, and Hims. This mix of scientific, regulatory, and consumer expertise allows us to reimagine how information flows between patients, providers, and the brands that serve them. Our founding team has built consumer products acquired by Google and enterprise technologies deployed across the Fortune 500. Backed by leading investors including RRE Ventures, Bling Capital, Founders Fund, and Greycroft, we’re scaling rapidly and redefining what digital health engagement can achieve. We are a remote-first team of around 70 (and growing!) united by curiosity, honesty, and a shared passion for improving healthcare. We call ourselves Ostronauts — explorers building the future of life sciences together. If you thrive in a collaborative, fast-moving environment and want your work to make a measurable impact on global health, come join us as we shape the next era of intelligent life sciences commercialization.
