IAM Architect

Job Overview We are seeking a senior Identity Management and Identity Governance & Administration (IGA) Architect to define and execute the firm's long-term identity strategy, governance model, target-state architecture, and technology roadmap. This individual will serve as the firm's identity subject matter expert, partnering with technology, cybersecurity, risk, compliance, audit, and business stakeholders to modernize the organization's identity capabilities and establish identity as a foundational security control across the enterprise. This role will assess the current Identity Provider and IGA landscape, including existing solutions, use cases, legacy systems, access governance processes, entitlement models, and application integrations. The candidate will identify what is working well, where gaps and risks exist, and define a clear path toward a modern, secure, scalable next-generation Identity Provider and IGA framework. This is a highly visible role requiring both strategic leadership and hands-on execution. The successful candidate will architect and help build the next-generation identity platform, manage the transition from legacy systems, strengthen SOC1-related identity controls, and partner closely with IT, security, cloud, application, infrastructure, risk, compliance, and audit stakeholders. Responsibilities Define and lead the firm's Identity and Access Management strategy, target-state architecture, operating model, and multi-year roadmap across identity governance, access management, privileged access, and non-human identities. Evaluate, select, and implement identity technologies and platforms, leading architecture reviews, technology assessments, proof-of-concepts, and vendor selection initiatives to support evolving business, security, and regulatory requirements. Establish enterprise identity standards, governance frameworks, and success metrics, while partnering with technology and business leaders to drive adoption, manage risk, and continuously mature the firm's identity capabilities. Own and lead the firm’s Identity Management, Identity Provider, and Identity Governance & Administration strategy and roadmap. Assess current identity solutions, IGA processes, access models, legacy integrations, and control gaps across the firm. Architect the next-generation identity and IGA framework covering human identities, non-human identities, privileged accounts, service accounts, workload identities, API identities, and AI agentic workload identities. Define and implement governance standards for joiner/mover/leaver processes, access requests, approvals, provisioning, deprovisioning, entitlement management, access reviews, and role models. Design modern authentication, authorization, federation, and delegation patterns using technologies such as OpenID Connect, OAuth 2.0, SAML, Kerberos, LDAP, Microsoft Entra ID, AWS IAM, Active Directory, and Secret Management platforms. Establish governance and lifecycle controls for non-human identities, including ownership, risk classification, access review, secret rotation, and least-privilege enforcement. Design identity patterns for On-Behalf-Of workflows, delegated permissions, service-to-service access, application impersonation, and AI/agent-based access scenarios. Lead the smooth migration of legacy applications and systems to the next-generation Identity Provider and IGA architecture. Partner with IT stakeholders to understand current challenges and define practical, secure, and scalable identity solutions. Own and improve SOC1-related controls for Identity Provider and IGA processes, including audit evidence, control documentation, access reviews, and remediation tracking. Remain hands-on in building and implementing identity solutions, integrations, workflows, standards, and proof-of-concepts. Requirements Demonstrated experience defining enterprise Identity and Access Management strategies, architectures, operating models in complex environments. Experience evaluating, selecting, and implementing identity technologies, including leading platform assessments, proof-of-concepts, vendor evaluations, and architecture review processes. Proven ability to influence and partner with senior technology, cybersecurity, risk, compliance, and business stakeholders to drive identity transformation initiatives and align identity capabilities with organizational objectives. Proven experience leading or supporting identity and IGA transformation programs in a large enterprise environment. Strong hands-on knowledge of IGA capabilities, including access request, approval workflows, provisioning, deprovisioning, joiner/mover/leaver processes, entitlement management, access certification, role-based access control, and application onboarding. Experience with major IGA platforms such as SailPoint, Saviynt, Omada, One Identity, Microsoft Entra ID Governance, or equivalent solutions. Deep technical knowledge of Microsoft Entra ID, on-premises Active Directory, AWS IAM, Kerberos, LDAP, federation, and hybrid identity environments. Strong understanding of OpenID Connect, OAuth 2.0, SAML, delegated authorization, On-Behalf-Of flows, and service-to-service authentication. Experience with non-human identity management, including service accounts, workload identities, machine identities, API identities, secret management, ownership models, and lifecycle controls. Experience with AI agentic workload identity, permission delegation, and autonomous or automated access patterns is strongly preferred. Strong understanding of SOC1 controls, audit readiness, access governance, privileged access controls, and identity-related risk management.
