Security Concierge Jobs

Who we are: Sardine is the leading agentic risk platform for fighting financial crime. Our integrated solution unifies data across risk teams to help organizations stop fraud in real time, prevent AI-driven attacks, and automate fraud and AML operations. Sardine’s platform is strengthened by one of the fastest-growing fraud consortiums in the market, spanning more than 6 billion profiled devices, 800 million consumers, and 3 million businesses worldwide. Leading companies including FIS, GoDaddy, Intuit, Edward Jones, ZoomInfo, and Checkout.com rely on Sardine to secure and grow trust in their products. Our culture: We hire talented, self-motivated individuals with extreme ownership and high growth orientation. We value performance and not hours worked. We believe you shouldn't have to miss your family dinner, your kid's school play, friends get-together, or doctor's appointments for the sake of adhering to an arbitrary work schedule. We're a remote-first team spread across time zones, so no office to report to - work from wherever helps you do your best work. Just a couple of things to keep in mind: pay is based on where you're located, and you'll need to keep a home base in the country you're hired in. So while we love the "coffee shop today, mountains tomorrow" life, this isn't a passport-optional, work-from-anywhere-on-Earth kind of remote - think flexible within your country, not borderless. Location: Remote - United States The role Sardine makes risk and payment decisions for banks and fintechs. Our customers audit us closely, and application security is a large part of what they examine. Money moves through this platform, so real adversaries study it. Your job is to find what they would find, especially authorization flaws and business logic abuse, and then make the whole class of bug go away. The application security team is small. The estate is large: Go, Node.js, Python, Ruby, and Java services running on multi-cloud and Kubernetes. That ratio shapes the wo

We partner across IT and Security to understand risk, build practical defenses, and support a rapidly evolving technical environment. About the Role We are looking for an Enterprise Security Engineer with a focus on vulnerability management, novel vulnerabilities, and zero-day response.

Translate technical findings into clear attack paths, business impact, and actionable remediation. Develop and validate emergency mitigations when patches are unavailable, coordinate with system owners, vendors, and incident responders, and drive durable fixes through verified closure. Improve asset visibility, ownership, vulnerability data quality, and reporting. Build and operate security tools and integrations using code, APIs, automation, and AI agents. Design controls for agent access, execution, and accountability. Contribute across endpoint, network, identity, and SaaS security, and support incident investigations when needed. You might thrive in this role if you: Have independently investigated novel or emerging vulnerabilities and driven enterprise remediation from uncertain initial reports through mitigation

About Ramp Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends.
