Security, Risk & Compliance

• Design identity controls aligned to Zero Trust principles and enterprise security policies.

• Partner with CSOC, audit, and risk teams on: Control validation Incident response Regulatory and audit requirements (SOX, SOC, internal controls)

• Contribute to risk assessments related to supplier dependency, SPOFs, and identity outages.

Collaboration & Influence

• Work closely with security architecture, infrastructure, application engineering, IAM operations, and vendors.

• Influence roadmap decisions through clear technical reasoning and executive-ready communication.

• Mentor senior and mid-level engineers and raise overall identity engineering maturity.

Qualifications

• Undergraduate degree in a related field or the equivalent combination of training and experience.

• 12+ years of experience in Identity & Access Management engineering.

• Skilled in using DevOps tools and experience in Policy as code.

• Deep hands-on expertise with Okta (Workforce Identity, MFA, SSO, policies, lifecycle).

• Strong working knowledge of Ping Identity products (PingFederate, PingOne, Ping Directory) or equivalent platforms.

• Expert understanding of identity standards: OAuth 2.0, OIDC, SAML Federation and token-based security

• Proven experience with directory services & LDAP (AD, cloud directories).

• Experience building identity platforms in AWS/GCP, including containerized/Kubernetes deployments.
