Capital markets are undergoing a fundamental shift. Assets that live in fragmented systems and manual workflows are moving onto blockchains -systems designed to move and store value more transparently and efficiently.
While this unlocks more open and programmable financial systems, it also introduces significant complexity. For most users, interacting with this new infrastructure is still too difficult.
Fun builds the infrastructure that powers consumer-facing fintech applications - handling onboarding, account access, and money movement so users can interact with blockchain-based systems as seamlessly as they do with traditional finance.
For fintech builders, Fun provides a best-in-class onboarding and deposit stack that drives conversion and unlocks user growth. We operate at the intersection of financial infrastructure, complex engineering, and product experience.
Our Security Lead covers application, cloud and AI security. We're hiring a Senior Corporate Security Engineer to own everything else that keeps Fun safe day to day: the identities, laptops, SaaS tools and vendors every employee and contractor depends on. Some companies call this enterprise security; whatever the name, it's the place where IT and security meet.
You'll be our first dedicated hire in this area, so you'll set the baseline as well as maintain it. We want someone who treats corporate security as an engineering problem. That means configuration in code, access granted by automation instead of by hand, and controls strong enough that a breached vendor or a phished employee is an inconvenience, not an incident.
Location and Work Environment This role is primarily in-person at our Midtown, NYC headquarters. We work together Monday through Thursday for fast, iterative collaboration and optional WFH Fridays to reset and recharge.
