  • Strong knowledge of REST, GraphQL, API gateways, microservices, HTTP, TLS, JSON, OAuth 2.0, OpenID Connect, JWT, API keys, mutual TLS, service identities, authorization, and common API abuse patterns.
  • Hands-on experience with enterprise API security and WAF platforms.
  • Experience analyzing security telemetry, investigating attacks, scripting in a common language, and integrating security platforms with SIEM, SOAR, ticketing, or workflow automation tools.
  • Experience with at least one major cloud platform (AWS, Microsoft Azure, or Google Cloud Platform), including API gateway, identity, logging, and load-balancing services.
  • Strong written and verbal communication skills to explain technical risk and remediation to engineering and non-technical stakeholders.
