TL;DR · API Security Engineer

The API Security Engineer joins the security team to build a best-in-class program protecting critical API ecosystems within the financial services sector. This role involves designing end-to-end protections, implementing runtime controls such as bot defense and mTLS validation, and providing secure design guidance based on OWASP standards. The engineer will integrate security into the DevSecOps lifecycle by building CI/CD automations, including policy-as-code and SAST/DAST testing. Key responsibilities include managing API inventories, developing telemetry dashboards, and ensuring compliance with NIST, ISO 27001, and PCI DSS frameworks. Required skills include expertise in OAuth2, OIDC, and JWT, along with experience using tools like Traceable, Salt Security, or NoName. The candidate will collaborate with product and platform teams to translate complex security signals into actionable, scalable controls for high-velocity engineering environments.

What you'll do

  • Implement and tune runtime controls such as behavioral detection, bot defense, and rate limiting across API gateways and service meshes.
  • Provide secure design guidance to engineering teams regarding authentication, authorization, input validation, and OWASP API Security standards.
  • Build automation for the CI/CD pipeline including policy-as-code, automated security checks, and secret scanning.
  • Develop dashboards and analytics using API telemetry to measure risk, control effectiveness, and program outcomes.
  • Establish governance for API inventories, ownership, classification, and consistent security requirements across the organization.
  • Integrate security requirements into the DevSecOps lifecycle through threat modeling, design reviews, and incident response planning.
  • Map security controls to industry frameworks like NIST, ISO 27001, and PCI DSS to ensure audit readiness.
  • Evaluate and pilot emerging technologies for API discovery, posture management, and runtime detection.

What we're looking for

  • You must possess valid and unrestricted U.S. work authorization.
  • A bachelor's degree or an MS is preferred.
  • CISSP or other professional cyber certifications are desirable.
  • 5+ years of related IT and cyber protection experience is desired.
  • You must have a strong foundation in API security concepts including OAuth2, OIDC, JWT, and rate limiting.
  • You must have practical experience with runtime protections such as API gateways, WAF/WAAP, or service mesh.
  • You must be able to build automation in CI/CD and cloud-native environments using policy-as-code and scripting.
  • You should have expert knowledge of cyber technologies like Traceable, Salt Security, or NoName.
