About The Position

Serve as the technical lead for workforce identity platforms, with Okta as the primary IdP and integrations to complementary platforms (e.g., Ping/Entra Identity). Own end‑to‑end identity architecture, including authentication flows, federation, directory integrations, and token issuance. Lead design reviews and decisions for IdP resiliency, failover, and supplier‑risk mitigation strategies. Document existing and new architecture and act as a hands‑on engineer while also setting technical direction, patterns, and standards. Strong communication, influence, and stakeholder‑management skills, with the ability to distill complex identity and security architectures into clear and concise messaging.

Requirements

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.
Strong troubleshooting skills for complex authentication and federation failures.
Ability to operate in high‑visibility, high‑impact environments.

Support directory deployments in cloud‑native environments (AWS/GCP, containers, Kubernetes).
Build and operate identity infrastructure in AWS/GCP/Azure, using Infrastructure & Policy as Code (Terraform / CloudFormation) and Kubernetes & containerized identity services.
Automate provisioning, deployment, monitoring, and drift detection for identity platforms.
Support SRE‑style operational maturity: SLIs/SLOs, alerting, incident response, and runbooks for identity services.
Design identity controls aligned to Zero Trust principles and enterprise security policies.
Partner with CSOC, audit, and risk teams on control validation, incident response, and regulatory and audit requirements (SOX, SOC, internal controls).
Contribute to risk assessments related to supplier dependency, SPOFs, and identity outages.
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.
