Senior Level Head of Service Management Jobs

Responsibilities

Identity and Access Management (IAM) owns the identity foundation for USDS JV: who every person, workload, and service is, how they authenticate, and what they are allowed to do. Our scope covers three connected domains: customer identity for our consumer and enterprise products (TikTok, CapCut, Lark, and others), workforce identity for full-time employees, contractors, and outsourced personnel, and access governance across more than 100,000+ microservices and applications. We work with product engineering, infrastructure, Trust and Safety, Cyber Defense, HR, privacy, legal, and compliance to make identity secure, reliable, and easy to use at very large scale. We are not just running directories and approval workflows. We engineer identity and authorization as a platform: consistent primitives, authoritative data, automated controls, and evidence that shows who has access to what, and why. Responsibilities:
- Own Customer Identity Across Products: Build and maintain a detailed understanding of the custom-developed customer identity and account systems behind TikTok, and other products, including registration, authentication, MFA and passkeys, session and token management, account recovery, account linking, and federation/SSO. Assess where architectures and controls diverge, set common security standards, and drive convergence on shared identity primitives where it reduces risk.
- Own Workforce Identity and Lifecycle: Direct identity for all worker populations, including FTEs, interns, contractors, outsourced and vendor personnel, and other non-employee identities. Establish authoritative HR and vendor sources of truth, sponsor ownership and expiration for non-employees, and automated joiner-mover-leaver workflows that provision on day one and revoke promptly on transfer or termination.
- Govern Privileged and Workload Access: Set standards for privileged access, just-in-time and break-glass access, service accounts, and service-to-service / workload identity. Reduce standing privilege and long-lived credentials in favor of short-lived, auditable, centrally managed access.
- Build Access Visibility Across 100,000+ Services: Build an entitlement inventory and access graph that answers who has access to what across 100,000+ services and applications, what each permission actually allows within that service, how access was granted, and who owns it. Resolve effective access across roles, groups, policies, and inherited permissions rather than relying on raw grants.
- Run Access Reviews and Least Privilege at Scale: Design a risk-based access review and certification program covering human and non-human identities, segregation-of-duties checks, and remediation of unused, excessive, or orphaned access. Push accountability to service owners through tooling, integration contracts, and automation rather than manual central review.
- Define Authorization Standards: Establish authorization models (RBAC, ABAC, relationship-based) and policy-enforcement patterns that product and infrastructure teams can adopt consistently. Make build-versus-buy decisions for IGA, PAM, directory, and policy-engine capabilities that balance security, reliability, cost, and long-term maintainability.
- Build and lead a high-performing organization and Own a department-level 6–12-month roadmap and an annual IAM security plan covering capability development, risk reduction, operational maturity, and resource needs in line with USDS JV's security priorities. Prioritize investment by identity risk exposure, business impact, service health, and available capacity.

Qualifications

Minimum Qualifications:
- Bachelor's degree in Computer Science, Engineering, Information Security, or a related field, or equivalent practical experience.
- 12+ years of experience in security engineering, identity engineering, or related infrastructure roles, including 5+ years leading teams in identity and access management, with hiring, performance management, and development of managers or technical leaders.
- A track record of defining identity architecture and department-level technical plans, or plans of comparable scope, and owning delivery and ongoing operation of enterprise-scale or consumer-scale identity services.
- Deep technical expertise in authentication and authorization, including OAuth 2.0, OpenID Connect, SAML, SCIM, MFA, FIDO2/WebAuthn and passkeys, session and token security, and RBAC/ABAC authorization models.
- Hands-on leadership experience with workforce identity lifecycle and identity governance, including joiner-mover-leaver automation, access reviews and certifications, privileged access management, and least-privilege programs.
- Strong engineering judgment across distributed systems, APIs, and data pipelines, with the ability to guide architecture and implementation decisions for high-availability, low-latency services.
- Ability to turn identity risk and business requirements into prioritized plans, influence partners across organizational boundaries, and explain technical trade-offs clearly to executives and engineers.

Preferred Qualifications:
- Experience leading consumer identity (CIAM) for products with hundreds of millions to billions of users, including account takeover prevention, account recovery, and balancing security with user experience.
- Experience assessing or consolidating multiple custom-built identity systems across different products or business units.
- Experience building entitlement discovery, effective-access analysis, or access-graph capabilities across thousands of services, and running access certification programs at that scale.
- Experience with fine-grained or relationship-based authorization (for example, Zanzibar-style systems) and centralized policy engines.
- Experience with workload and service identity, including mTLS, SPIFFE/SPIRE or equivalent, secrets management, and eliminating long-lived credentials.
- Experience managing identity for large contractor and outsourced workforces, including vendor-sourced identity data and sponsor-based access.
- Experience with enterprise IGA, PAM, and directory platforms (for example, SailPoint, CyberArk, Okta, Microsoft Entra ID) as well as custom-built alternatives.
