Who You Are Have 7+ years of experience in security or infrastructure engineering roles, with demonstrated ownership of enterprise security domains such as SaaS security, IAM, Zero Trust, endpoint security, or cloud-delivered security services Approach every project AI-first: you design with AI, refine with AI, and take full responsibility for validating and owning what you deploy — you are not a passive consumer of AI output Hands-on by default — you are equally comfortable writing policy-as-code, reviewing architecture, and debugging a production issue Proficient with Terraform for building and maintaining infrastructure-as-code across enterprise security systems Experienced operating in AWS environments, with strong familiarity with cloud security services, IAM policies, and secure architecture patterns Experience with enterprise IdP solutions such as Okta, AWS Cognito Experienced with enterprise security tooling such as Cloudflare (WAF, gateway), Wiz (CNAPP/cloud security), and CrowdStrike (EDR/endpoint) Knowledgeable in secrets management, JITA, and modern identity patterns including SSO, SCIM, and privileged access workflows including SAML 2.0, SCIM, OAuth and OIDC — note this is not a dedicated IAM role; fluency in these areas supports broader enterprise security ownership, not identity program management Experienced mentoring engineers and working through influence: you raise the bar for the people around you and hold team-wide technical standards
