Job description

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.

What you'll own:

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  • Tie device health to access so an unmanaged or out-of-date laptop can't reach sensitive systems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

Your first 90 days

  • 30 days: You know every identity, device and critical SaaS app we run, and where the gaps are
  • 60 days: SSO, MFA and automated offboarding are complete across the core stack, and every laptop is enrolled in MDM with EDR running
  • 90 days: Core identity and SaaS configuration is managed as code, there's a working vendor review process, and the corporate security roadmap for 2027 is written and agreed

You might be a fit if you have:

  • 5+ years in corporate security, enterprise security or security-minded IT engineering, ideally at a fast-growing startup
  • Deep hands-on experience with an identity provider (Okta, Entra ID, or Google Workspace as IdP), including SSO, SCIM and conditional access
  • Experience running macOS fleets securely with an MDM (Jamf, Kandji, Fleet or similar) and EDR
  • Automation skills: you write Python, Bash or similar against APIs to remove repetitive work
  • Heavy daily use of AI tools like Claude Code, and good judgment about where they help and where they create risk
  • Sound, risk-based judgment, and the ability to explain a tradeoff to an engineer, a salesperson or an executive and leave them agreeing

Nice to Have:

  • Terraform or other config-as-code for identity, MDM or SaaS
  • Experience at a crypto, fintech or payments company, especially one with real money at stake
  • Having taken a company through SOC 2 or ISO 27001
  • Incident response or SOC background
  • Familiarity with blockchain analytics and transaction screening tools (Chainalysis, TRM)
  • Experience supporting a team split across time zones
Why Join Us
● Shape the future of payments and programmable money
● Work with bleeding-edge tech in a domain where innovation moves fast
● Join a mission-driven team focused on access, openness, and trust
● Be a key contributor, not just a cog—your work will ship fast and matter
● Collaborate with top-tier protocols, builders, and financial infrastructure providers
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.
