About the Team

Product Security at Chainalysis keeps our SaaS platform — used by governments, banks, and crypto exchanges to investigate financial crime — secure by design. We partner directly with product and platform engineering on threat modeling, design reviews, penetration testing, and remediation of findings across our AWS and Kubernetes estate.

As a Staff Product Security Engineer, you'll be the technical lead for product security across one or more product areas. You'll run security reviews for new launches and AI tooling, perform hands-on pentests, ship code and fixes directly into product repos, own our Vulnerability Disclosure Program, and drive SOC2 and risk-framework work across R&D. You'll participate in a shared on-call rotation for production security incidents.

In this role, you'll:

• Lead Product Security across Chainalysis' SaaS offerings, partnering with product and platform engineering teams on design, code, and remediation
• Own Unified Security Review process for new product launches, vendor evaluations, and AI tooling — including custom penetration tests scoped to each review
• Drive Security Engineering Risk Management Framework, for consistent risk classification and remediation tracking across product
• Lead the Vulnerability Disclosure Program and security bug reporting workflow, from researcher intake through fix
• Drive SOC2 and compliance-related security remediation across product engineering, partnering with R&D leads on architectural fixes
• Provide security review and guardrails for internal AI platforms and coding agents (LLM gateways, prompt/response controls, agent permissioning)
• Participate in a shared on-call rotation for high-severity production security incidents

We're looking for candidates who have:

• 8+ years of application security engineering experience
• Strong production coding ability in at least one of Java (preferred), TypeScript/JavaScript, Python, or Go — enough to perform deep code review, write proof-of-concept exploits, and contribute fixes directly into product repos
• Building security automation into CI/CD pipelines
• Hands-on penetration testing of production SaaS applications, including custom tests scoped to new product launches
• Threat modeling, secure design reviews, and static/dynamic code analysis across the SDLC
• Identifying and remediating common web application vulnerabilities (OWASP Top 10)
• Experience securing internal AI/LLM platforms and coding agents (model gateways, prompt/response controls, agent permissioning)

Nice to have experience:

• Experience in Web3, Blockchain, or Digital Assets
• Experience building AI workflows, agents, and guardrailing

Technologies we use:

• Cloud and containers: AWS, GCP, Kubernetes (EKS/GKE)
• Infrastructure-as-Code: Terraform
• Security tooling: Wiz, SonarCloud, Burp, Cloudflare
• CI/CD and source control: GitHub, GitHub Actions, Artifactory and related build/deploy tooling
• Languages and scripting: Java, JavaScript, Python, Go
• AI Coding Agents, Tooling, Systems
