Head of Security

About Plenful

Plenful is on a mission to transform healthcare operations from the inside out. Fresh off our $50M Series B and backed by Notable Capital, Bessemer Venture Partners, TQ Ventures, Susa/Kivu Ventures, and other leading investors, we’re building the category-defining AI automation platform that healthcare teams rely on to operate smarter, faster, and more efficiently. Our technology empowers healthcare operators across hospital and health systems, pharmacies and payors to eliminate manual work, reduce administrative burden, and improve compliance, all while unlocking critical revenue to fund programs for their in-need patient populations.

Built by healthcare operators for healthcare operators, Plenful is driven by a deep understanding of the challenges facing today’s care teams. We’re passionate about equipping healthcare workers with world-class tools that deliver real, measurable impact, and we’re proud to serve 100+ leading health systems, pharmacies, and healthcare organizations across the country. If you’re excited to help shape the future of healthcare, we’d love to meet you. Apply now to join our growing team.

About the Role

Security is now a strategic differentiator for Plenful, and we're building the function from the ground up. As Head of Security, you'll own security across the company — product and application security, cloud infrastructure, corporate security, governance, compliance, and customer trust.

You'll set the strategy, hire the team, and build the processes that let us scale securely without losing the speed of a high-growth startup. You'll partner across Engineering, Product, IT, Legal, and Executive Leadership to embed security into everything we build.

We're looking for a builder — someone who's comfortable in ambiguity, has stood up security programs from zero before, and wants to build an organization that scales with the business.

In your first 12 months, you'll build and execute a company-wide security roadmap, stand up a high-performing security organization, mature our cloud, application, and corporate security capabilities, and strengthen the compliance and customer trust programs that support enterprise growth.
