TL;DR · API Security Engineer

As an API Security Engineer, you will join the security team to build a best-in-class program protecting critical API ecosystems within the financial services sector. You will be responsible for implementing runtime protections such as behavioral detection, bot defense, and rate limiting across gateways and service meshes while providing secure design guidance based on OWASP standards. Your daily work involves building automation for CI/CD pipelines, including policy-as-code and SAST/DAST testing, and developing analytics dashboards from telemetry to measure risk. You will utilize tools like Traceable, Salt Security, and NoName to manage discovery and posture. Key technical competencies include expertise in OAuth2, OIDC, JWT, and mTLS, alongside experience with Open API schemas. You will ensure compliance with industry frameworks like NIST, ISO 27001, and PCI DSS to secure modern financial infrastructure.

What you'll do

  • Implement and tune runtime controls like behavioral detection, bot defense, and rate limiting across gateways and service meshes.
  • Provide engineering teams with guidance on secure API patterns including authentication, authorization, and input validation.
  • Build automation to integrate security checks, policy-as-code, and scanning tools into the CI/CD pipeline.
  • Develop dashboards and analytics from API telemetry to measure risk and inform leadership decisions.
  • Establish governance for API inventories, ownership, classification, and consistent security standards across teams.
  • Integrate security requirements into the DevSecOps lifecycle through threat modeling, design reviews, and incident response.
  • 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

  • 5+ years of related IT and cyber protection experience is desired.
  • Bachelor’s degree in computer science, a relevant field, or an equivalent combination of education, work, and military experience.
  • Strong foundation in API security concepts including OAuth2, OIDC, JWT, rate limiting, and schema validation.
  • Practical experience with runtime protection using API gateways, WAF/WAAP, service mesh, or specialized API security platforms.
  • Experience building automation in CI/CD and cloud-native environments using policy-as-code and scripting.
  • Expert knowledge of cyber technologies such as Traceable, Salt Security, and NoName.
  • CISP or other professional cyber certification is desirable.
  • Must possess valid and unrestricted U.S. work authorization without requiring sponsorship.
