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.

 

 

About the Role

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.

 

Identity and access

Run SSO, MFA and automated provisioning (SCIM) across Google Workspace and the rest of our stack

Build joiner/mover/leaver flows so new hires have the right access on day one and departing people lose it within minutes

Run regular access reviews and keep admin and privileged access to a minimum

Endpoints

Define and enforce macOS baselines through MDM: disk encryption, EDR, OS updates, device compliance

Tie device health to access so an unmanaged or out-of-date laptop can't reach sensitive systems

Address the new risks of AI agents and coding assistants running on employee machines, including what they can read, where data goes and what they're allowed to run

SaaS security

Harden Slack, Notion, Google Workspace, our CRM and the rest of the stack: least privilege, external sharing and guest controls, and data protection guardrails

Find and reduce shadow IT, and keep seats and licenses tight

Vendors and third parties

Run security reviews for new vendors and integrations, and maintain a tiered inventory of the ones we can't operate without

Plan in advance for when a critical vendor is breached or goes down, so we're never improvising

Detection and response

Make sure identity, endpoint and SaaS activity is logged and actionable

Own corporate incidents such as phishing, account takeover and lost devices, and take part in company-wide incident response and blameless postmortems

Compliance and customer trust

Own the corporate and IT controls for SOC 2 and similar frameworks, with evidence collected automatically rather than by screenshot

Help answer enterprise customers' security questionnaires and reviews
