TL;DR · API Security Engineer

The API Security Engineer joins the security team to build a best-in-class API security program for modern financial services. This role involves shaping end-to-end security from design through runtime by partnering with product, platform, and security engineers. Key responsibilities include implementing runtime protections like behavioral detection, bot defense, and mTLS validation across API gateways and service meshes. The engineer will provide secure design guidance based on OWASP API Security Top 10, build CI/CD automation for policy-as-code and secrets scanning, and develop telemetry dashboards to measure risk. Required skills include expertise in OAuth2, OIDC, JWT, and tools like Traceable, Salt Security, and NoName. The role ensures secure engineering by mapping controls to NIST, ISO 27001, and PCI DSS frameworks within a financial services context.

What you'll do

  • Implement and tune runtime controls like behavioral detection, bot defense, and rate limiting across API gateways and service meshes.
  • Provide engineering teams with secure API design guidance for authentication, input validation, and error handling.
  • Build automation to embed security checks, secrets scanning, and policy-as-code into CI/CD pipelines.
  • Develop dashboards and analytics using API telemetry to measure risk and control effectiveness.
  • Define governance for API inventories, ownership, classification, and security requirements.
  • Integrate security requirements into backlog planning, threat modeling, and incident response workflows.
  • Map security controls to industry frameworks like NIST, ISO 27001, and PCI DSS for audit readiness.
  • Evaluate and pilot emerging technologies for API discovery and posture management.

What we're looking for

  • Must possess valid and unrestricted U.S. work authorization.
  • Bachelor’s degree in computer science, a relevant field, or an equivalent combination of education, work, and/or military experience.
  • 5+ years of related IT and cyber protection experience (preferred).
  • Strong foundation in API security concepts including authN/authZ (OAuth2/OIDC, JWT), session/token handling, rate limiting, and schema validation.
  • Practical experience with runtime protection in API gateways, WAF/WAAP, service mesh, ingress controllers, or specialized API security platforms.
  • Experience building automation in CI/CD and cloud-native environments using policy-as-code, scripting, and Git-based workflows.
  • Expert knowledge of and experience maintaining cyber technologies such as Traceable, Salt Security, and NoName.
  • CISSP or other professional cyber certification (preferred).
