Identity & Access Management Architect – Okta Migration

Rivian • Palo Alto, CA

10h • Hybrid

About The Position

Client is seeking a hands-on IAM Architect to lead our enterprise workforce identity migration from Microsoft Entra ID to Okta (~1,800 users), targeting a federation cutover in Q3 2026. You will own the migration architecture end-to-end — federation design, app integrations, cutover, and stabilization — working alongside our internal Enterprise Cybersecurity team and an external implementation partner. Beyond the migration, you'll help build and operate our identity ecosystem, with the opportunity to contribute to a custom identity orchestration and governance platform. This is a 6-month contract with strong potential for conversion to a full-time role.

Requirements

• 7+ years in identity and access management, with 3+ years hands-on Okta experience building, deploying, and maintaining Okta Workforce Identity Cloud environments.
• At least one completed enterprise migration from Entra ID / Azure AD to Okta as architect or technical lead.
• Deep expertise in SAML, OIDC, OAuth 2.0, SCIM, and directory integration (AD/Entra ID hybrid scenarios).
• Experience operating and administering Okta in production: policy management, app integrations, lifecycle workflows, troubleshooting.
• Experience designing MFA and adaptive access policies at enterprise scale.
• Strong documentation skills; able to produce audit-ready artifacts.
• Proven ability to work alongside system integrators while retaining architectural ownership.

Nice To Haves

• Okta Certified Consultant or Okta Certified Architect.
• Experience building custom identity automation or governance tooling using Python/SQL, event-driven pipelines, and APIs.
• Working knowledge of data platforms (Databricks, Spark, or comparable) for event ingestion and processing.
• Experience with ABAC/policy-based authorization models and JIT/ephemeral privileged access patterns in AWS.
• SIEM integration experience (log normalization, detection engineering for identity signals).
• Familiarity with IGA platforms, PAM solutions, and enterprise password managers.
• Experience in regulated or automotive environments (TISAX, ISO 27001, NIST 800-53).

Responsibilities

• Lead technical architecture for the Entra ID to Okta workforce identity migration: federation design, app integration sequencing, cutover planning, rollback strategy, and hypercare.
• Design and build SSO/SAML/OIDC integrations across the enterprise application portfolio; architect multi-tenant deployment (separate US/EU tenants) to meet regional data requirements.
• Architect lifecycle management and provisioning workflows (HR-driven joiner/mover/leaver), including SCIM integrations.
• Define and implement MFA, adaptive authentication, and device assurance policies aligned to a zero-trust roadmap.
• Serve as technical counterpart to the implementation partner: review designs, challenge assumptions, hold delivery quality to standard.
• Maintain and operate the Okta environment post-cutover: policy tuning, integration onboarding, incident support, and operational runbooks.
• Produce audit-ready documentation for an ISO 27001 / TISAX-aligned control environment.
• Contribute to the design and build of a custom identity orchestration layer (Databricks or equivalent): attribute-driven provisioning, ABAC policy models, JIT privileged access, anomaly detection, automated deprovisioning, and audit/recertification capabilities.
• Support integration of identity and authorization event logs into the cybersecurity SIEM.
