Job Description

At Uni Systems, we are working towards turning digital visions into reality. We are continuously growing and we are looking for an Identity & Access Management Architect to join our UniQue team.

What will you be doing in this role?

  • Define and maintain modern authentication standards and reference architectures for applications and APIs using OAuth2, OIDC, and SAML.
  • Support project teams in implementing, troubleshooting, and securing authentication flows (Auth Code + PKCE, Device Code, Client Credentials, OBO), including production incident resolution.
  • Design and standardize token, session, claims, and permission strategies, including least-privilege access, consent governance, IdP normalization, and scalable API authorization models.
  • Configure and operate federation integrations (IdP/SP), including metadata management, certificate rollovers, and SSO troubleshooting.
  • Design and implement risk-based access controls, Conditional Access policies, MFA strategies, and phishing-resistant authentication aligned to application sensitivity.
  • Deliver and improve Entra ID tenant configurations, governance controls, and operational security posture.
  • Design and support external identity onboarding patterns (Entra External ID CIAM/B2B/B2C), balancing usability, security, and operational supportability.
  • Implement and operate Entra ID Governance and SailPoint IGA capabilities, including JML, access requests, certifications, SoD, entitlement management, lifecycle workflows, and role modeling.
  • Support application onboarding and integrations involving Enterprise Apps, App Registrations, service principals, managed identities, and hybrid identity dependencies.
  • Operate and modernize hybrid identity environments involving AD DS/AD FS, including federation, delegation, group structures, and cloud transition planning.
  • Develop and maintain PowerShell automation and operational tooling for identity lifecycle management, reporting, governance checks, troubleshooting, and repeatable operational tasks.
  • Design and improve provisioning and lifecycle integrations (SCIM, authoritative sources, reconciliation, JIT vs managed provisioning) while ensuring GDPR/EUDPR compliance, auditability, and access hygiene, including AI/agent identities where applicable.

Requirements

What do you need to succeed in this position?

  • Bachelor’s degree in IT or related field with 10+ years of experience, including 8+ years in IT security.
  • Strong experience with Entra ID / Entra External ID, enterprise app/API integrations, and hybrid identity environments (AD DS/AD FS).
  • Strong understanding of OAuth 2.0, OpenID Connect, SAML, token/session lifecycles, consent models, and enterprise authentication/authorization patterns.
  • Hands-on experience implementing and troubleshooting modern authentication flows (Auth Code + PKCE, Device Code, Client Credentials, OBO), claims mapping/normalization, and SSO integrations.
  • Experience with Enterprise Apps, App Registrations, service principals, managed identities, and IdP/SP federation integrations.
  • Strong knowledge of Conditional Access, MFA, phishing-resistant authentication, risk-based access controls, and safe rollout/break-glass practices.
  • Experience with CIAM/B2B/B2C onboarding patterns and balancing UX with security requirements.
  • Experience with SailPoint governance, JML processes, access requests, certifications, SoD, role/entitlement models, and provisioning approaches (SCIM, JIT, managed provisioning).
  • Solid understanding of AD DS concepts including domains/forests, trusts, delegation, OU/GPO, and hybrid identity impacts.
  • Experience designing IAM controls aligned with GDPR/EUDPR, auditability, traceability, and least-privilege principles, including AI/agent identities.
