Cybersecurity IAM Architect - Staff Engineer

OneMain Financial; Baltimore (MD); On-site; USD 150,000 - 190,000; Full time

Job summary

OneMain Financial is seeking an IAM Architect to design enterprise-wide identity security architectures aligned to NIST, spanning cloud, on‑premises, SaaS, and hybrid environments.

You will translate business and regulatory requirements into secure IAM blueprints, lead architecture reviews, and mentor junior engineers. Strong collaboration with IT, risk, and product teams is essential.

Qualifications

• 7-10 years in cybersecurity with 3+ years in IAM architecture or related design role
• Deep working knowledge of NIST CSF, SP 800-53, SP 800-171, and SP 800-207 Zero Trust
• Experience designing IAM architectures for enterprise systems, cloud, SaaS, APIs, and hybrid environments
• Strong understanding of IAM domains: lifecycle management, SSO, MFA, federation, PAM, RBAC, ABAC, PBAC, access reviews
• Hands-on familiarity with Okta, Entra ID, SCIM, SAML, OAuth, OIDC, LDAP, Kerberos, and privileged access technologies
• Strong understanding of AI/GenAI security concepts: agent identities, delegated access, auditability of agent actions
• Experience in regulated environments and aligning identity controls to compliance frameworks
• Excellent communication, collaboration, documentation, and executive-facing presentation skills

Responsibilities

• Lead IAM architecture reviews for new technologies, applications, AI agents, and enterprise systems
• Identify identity-related gaps such as over-permissioned roles, shared credentials, weak delegation
• Advise on risk mitigation for authentication, authorization, privileged access, and secrets management
• Collaborate with engineering, cloud, infrastructure, and AI teams to ensure secure deployment
• Provide guidance to project and product teams throughout the SDLC with secure-by-design IAM controls
• Develop and maintain IAM standards and identity governance frameworks

Job description

Architecture & Solution Design

• Develop enterprise-wide IAM and identity security architectures aligned to NIST standards, including NIST CSF, SP 800-53, SP 800-171, and SP 800-207 Zero Trust principles

• Design scalable identity solutions for authentication, authorization, federation, lifecycle management, access governance, privileged access, and policy enforcement across cloud, on-premises, SaaS, and hybrid environments

• Define secure design patterns for AI agent identities, non-human identities, workload identities, service accounts, API access, secrets, delegated authority, and agent-to-tool interactions

• Translate business, regulatory, and technical requirements into secure IAM solution blueprints, reference architectures, and reusable identity patterns

• Establish least-privilege access models using RBAC, ABAC, PBAC, just-in-time access, dynamic credentials, and context-aware controls where appropriate

Solution Review & Risk Mitigation

• Lead IAM architecture and security reviews for new technologies, applications, AI agents, automation platforms, APIs, and enterprise systems

• Identify identity-related gaps in proposed solutions, including over-permissioned roles, shared credentials, weak delegation models, insufficient audit trails, and unmanaged non-human identities

• Advise on risk mitigation strategies for authentication, authorization, privileged access, identity lifecycle, secrets management, token use, tool binding, and agent runtime access

• Collaborate with engineering, cloud, infrastructure, application, and AI platform teams to ensure secure deployment of identity-enabled systems and services

• Provide technical guidance to project and product teams throughout the system development lifecycle, with emphasis on secure-by-design IAM controls

Governance & Standards

• Develop and maintain IAM architecture standards, identity control frameworks, access governance policies, and secure design patterns in alignment with NIST and industry best practices

• Participate in or lead internal security governance boards and architecture review boards with a focus on identity risk, Zero Trust alignment, and AI agent access governance

• Ensure solutions meet internal risk, compliance, and regulatory requirements, including CMMC, PCI DSS, and audit expectations for identity controls

• Define governance expectations for joiner/mover/leaver processes, entitlement reviews, separation of duties, privileged access, service account ownership, non-human identity inventories, and exception management

• Contribute to maturity assessments and continuous improvement efforts for IAM architecture, identity governance, and AI agent identity management capabilities

Collaboration & Leadership

• Act as a subject matter expert on IAM, Zero Trust identity, non-human identity governance, and AI agent identity security for stakeholders across IT, engineering, compliance, risk, and AI product teams

• Mentor junior architects and security engineers on identity architecture, secure access patterns, and governance-driven solution design

• Communicate complex identity, access, AI agent, and risk concepts clearly to business leaders and non-technical audiences

• Stay up to date on emerging threats, identity technologies, AI agent security patterns, and changes to the NIST ecosystem

Required Qualifications

• 7-10 years of experience in cybersecurity, with 3+ years in IAM architecture, security architecture, or a similar solution design role

• Deep working knowledge of NIST frameworks, including CSF, SP 800-53, SP 800-171, and SP 800-207 Zero Trust

• Demonstrated experience designing and reviewing IAM architectures for enterprise systems, cloud environments, SaaS platforms, APIs, and hybrid environments

• Strong understanding of IAM domains including identity lifecycle management, IGA, SSO, MFA, federation, PAM, RBAC, ABAC, PBAC, entitlement management, access reviews, and separation of duties

• Hands-on familiarity with identity platforms and standards such as Okta, Microsoft Entra ID, SCIM, SAML, OAuth, OIDC, LDAP, Kerberos, and privileged access technologies

• Strong understanding of LLMs, AI, and GenAI solutions, including agentic AI, MCP/tool hardening, non-human identity governance, agent-to-tool authorization, delegated access, and auditability of agent actions

• Experience working in a large regulated environment and aligning identity controls to compliance frameworks

• Excellent communication, collaboration, architecture documentation, and executive-facing presentation skills

Preferred

• Industry certifications such as CISSP, CISM, CISA, CCSP, or identity-focused certifications

• Experience with Zero Trust Architecture, modern identity security models, and enterprise access governance programs

• Experience with policy-as-code, DevSecOps, infrastructure-as-code security, and automated identity control validation

• Experience developing governance models for non-human identities, machine identities, workload identities, AI agents, service accounts, secrets, and API credentials
