Flourish CISO

About the position We are seeking a hands-on, deeply technical, and strategic Chief Information Security Officer (CISO) to lead our cybersecurity program. As a "player-coach,” you will be responsible for setting the security vision and strategy while also rolling up your sleeves to architect and implement robust security controls. You will be the senior-most leader for information security, tasked with protecting our firm, our partners, and our clients across our diverse and highly regulated business lines. This is a critical leadership role for a security expert who thrives on building, securing, and scaling modern, cloud-native financial technology. Since 2017, Flourish has been on a mission to help financial advisors evolve from holistic advice to holistic implementation to more fully serve their clients and achieve better outcomes. We focus on independent Registered Investment Advisors (RIAs), delivering financial products that advisors can't easily access today through beautiful, scalable, and easy-to-use technology. Today, we work with over 1,000 RIAs that collectively represent more than $2.6T in assets under management across two products — Flourish Annuities and Flourish Cash — and with our recent acquisition of Sora Finance, we'll be adding a lending offering in 2026. Headquartered in New York City, we are an independently-operating, wholly-owned subsidiary of MassMutual Life Insurance Company. Read on if you are interested in joining a small, highly-collaborative, rapidly-growing startup—backed by the support and stability of a Fortune 500 company.
