Backed by Greylock, NEA and Entrepreneur First.
About the role
You will be the most senior hands-on application security engineer at Cleo, owning both how security is built into our products from design through release and the security posture of the products we ship, both on-premise and SaaS, as our customers experience them. This is a Staff-level individual contributor role with real program ownership: you set the standards, build the guardrails, and work directly with engineers in the code. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Own and mature Cleo’s SSDLC: security requirements, threat modeling, and design reviews for high-risk product changes, APIs, and integrations
- Run and tune SAST, SCA, secrets detection, container, and IaC scanning
- Build reusable secure patterns, reference implementations, and policy-as-code controls that make the secure path the default path
- Own the penetration testing program: scope and coordinate third-party engagements, perform targeted testing yourself, and validate findings through retesting
- Run our Vulnerability Disclosure Program, including researcher communications and coordinated disclosure
- Coordinate the CVE lifecycle for Cleo products and support product-security incident response

You report to the CISO and partner daily with Engineering, and our Cloud Security team. You are not a one-person department: security engineers and consulting partners execute under your direction. Your job is to set direction, make the hard technical calls, and build leverage through automation and partners rather than carry every task yourself.
