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 aligned with OWASP standards. The engineer will integrate security into the DevSecOps lifecycle by building automation for CI/CD pipelines, performing threat modeling, and developing data analytics to measure risk. Key technical requirements include expertise in OAuth2, OIDC, JWT, and schema validation, alongside experience with API gateways, WAFs, and service meshes. Candidates should be proficient in policy-as-code, scripting, and tools like Traceable, Salt Security, or NoName. The role ensures compliance with industry frameworks such as NIST, ISO 27001, and PCI DSS while securing high-velocity financial data flows.

What you'll do

  • Implement and tune runtime controls such as behavior 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 from 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 equivalent work experience is required.
  • 5+ years of related IT and cyber protection experience are desired.
  • CISSP or other professional cyber certification is desirable.
  • You must have a strong foundation in API security concepts including authN/authZ, session handling, and rate limiting.
  • You must have practical experience with runtime protection tools 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.
  • Experience with OpenAPI tooling, threat modeling, and aligning controls to financial industry standards is preferred.
