Principal Engineer

Key Responsibilities

IAM & Directory Services Architecture Ownership

• Act as the principal technical owner for global IAM and directory services platforms supporting enterprise, partner, and customer-facing applications
• Define, document, and evolve end-to-end IAM architecture, including:
• Active Directory (enterprise-scale, hybrid, multi-region)
• Entra ID / Azure AD (including B2C and external identities)
• Oracle Unified Directory (OUD)
• Linux and Unix authentication and authorization integrations
• Establish reference architectures, engineering standards, and operational patterns for identity platforms
• Design for high availability, fault tolerance, disaster recovery, and regional resilience

Authentication & Authorization Reliability

• Ensure continuous availability of authentication and authorization services by proactively managing identity dependencies
• Own directory synchronization, federation, and authentication flows across hybrid environments
• Eliminate architectural and operational single points of failure
• Prevent identity issues that could result in:
• Global user access degradation
• Business application downtime
• Customer- and partner-facing access disruption

Security, Zero Trust & Risk Reduction

• Make identity the primary control plane for Zero Trust initiatives
• Enforce least privilege, strong authentication, and continuous verification
• Design and implement RBAC, ABAC, and policy-based authorization models
• Strengthen directory security posture by addressing:
• Privileged access exposure
• Legacy protocols and weak authentication mechanisms
• Inconsistent policy enforcement and configuration drift
• Reduce identity-based attack paths and systemic access risk
  

Non-Human, AI & Machine Identity Protection

• Architect and secure non-human identities, including:
• AI agent identities
• Robotic Process Automation (RPA) identities
• Service accounts, workloads, APIs, and system identities
• Define lifecycle management, authentication, authorization, and rotation strategies for machine identities
• Prevent credential sprawl, over-privileged access, and unmanaged secrets
• Ensure AI and robotic identities adhere to Zero Trust, least privilege, and auditable access principles
• Integrate non-human identity controls into enterprise IAM governance and monitoring

Integration & User Experience

• Improve identity integration across:
• Enterprise applications
• Partner platforms
• Customer-facing (B2C) ecosystems
• Ensure seamless, low-friction authentication experiences without compromising security
• Enable scalable access models for human and non-human identities
  

Mergers & Acquisitions (M&A) Support

• Serve as the IAM technical lead for M&A initiatives
• Assess acquired company identity architectures, directory services, and authentication models
• Design and execute secure identity integration, consolidation, or coexistence strategies
• Mitigate access risk during transitions while maintaining business continuity
• Ensure acquired environments align with enterprise IAM, Zero Trust, and security standards

Continuity, Innovation & Long-Term Strategy

• Ensure knowledge continuity and eliminate dependency on individual resources
• Define a multi-year IAM and directory services roadmap aligned with enterprise architecture and Zero Trust maturity
• Evaluate emerging identity technologies, protocols, and access models, including AI-driven identity use cases
• Mentor engineers and elevate IAM engineering maturity across the organization

Experience

Required Qualifications

• 12+ years of experience in Identity & Access Management, directory services, or security platform engineering
• Proven experience supporting global, highly available, business-critical identity systems

Technical Expertise

• Architectural-level expertise in:
• Active Directory (enterprise and hybrid environments)
• Entra ID / Azure AD, including B2C
• Oracle Unified Directory (OUD)
• Linux and Unix authentication mechanisms
• Strong understanding of:
• Authentication and authorization flows
• Identity federation and synchronization
• RBAC, ABAC, and policy-driven access models
• Zero Trust and identity-centric security architecture
• Hands-on experience with identity protocols:
• SAML 2.0, OAuth 2.0, OpenID Connect (OIDC), Kerberos, LDAP/LDAPS, SCIM, RADIUS, SSH key-based authentication, PAM (Pluggable Authentication Modules) for Linux, certificate-based authentication (X.509), and modern API-based identity integrations, etc.
• Experience with automation and integration:
• PowerShell, Python, APIs, infrastructure-as-code preferred
  

Architectural & Leadership Skills

• Ability to design for availability, resilience, and failure scenarios
• Strong systems thinking and long-term technical judgment
• Proven ability to influence architecture and strategy across teams without formal authority
• Comfortable operating in ambiguous, high-impact environments

Preferred Qualifications

• Experience supporting customer-facing digital platforms at global scale
• Cloud IAM experience across Azure, AWS, and/or GCP
• Familiarity with identity governance, privileged access, and compliance frameworks
• Experience working with globally distributed teams, including India-based engineering support models
• Prior experience supporting identity integration during M&A activities

Why This Role Is Critical

Identity is a Tier-0 dependency. Without a resilient, well-architected IAM foundation, failures in authentication, authorization, or machine identity control quickly become enterprise-wide risk events.

This Role Directly Protects The Organization From

• Identity-driven downtime and degraded user access
• Over-privileged or unmanaged AI, robotic, and service identities
• Increased risk during mergers, acquisitions, and integrations
• Delays or failures in Zero Trust adoption
• Compliance exposure and erosion of trust

This Principal Engineer ensures continuity, resilience, and long-term sustainabiliy of identity services—across humans, machines, and AI—that the business depends on every day.
