You will be the technical authority defining the architecture and long-term vision for identity and access management systems that secure thousands of enterprise customers globally.

The Auth Platform team is responsible for both internal and external AuthN and AuthZ. The team is a very critical part of CrowdStrike's cloud platform, frequently collaborating with many product groups across the organization. The team builds and extends services that are capable of making 1+ trillion decisions per day — making reliability, scale, and security non-negotiable.

PLEASE NOTE: This role is hybrid, requiring 2-3 days per week on-site at one of the posted locations.

What You'll Do:

Own and drive the technical strategy and roadmap for the Auth Platform

Architect and evolve our multi-tenant identity infrastructure supporting MSSP (Managed Security Service Provider) models — including hierarchical tenancy, delegated administration, cross-tenant access patterns, and fine-grained access controls

Design and scale high-volume authentication systems and extremely high-volume authorization systems capable of handling millions of AuthN and trillions of AuthZ decisions with ultra-low latency and 99.999% (5 nines) availability

Lead cross-region AuthN/AuthZ architecture ensuring consistent, secure, and performant identity operations across global deployments

Drive the vision for next-generation authentication systems — including passwordless, continuous authentication, and AI-driven adaptive access controls

Lead the design of fine-grained access controls including ABAC, ReBAC, and policy engine frameworks

Define standards for OAuth 2.0, OIDC, SAML, FIDO2/WebAuthn, and token lifecycle management

Drive Zero Trust and adaptive authentication initiatives

Mentor senior engineers and elevate the technical bar across the organization

Partner with Product, Security, and Engineering teams to align on priorities and deliver outcomes

What You'll Need:

15+ years of software engineering experience with 6+ years in identity/auth systems

Deep expertise in multi-tenant SaaS architecture including MSSP or hierarchical tenancy models with fine-grained access controls at scale

Proven experience building and operating high-volume authentication and extremely high-volume authorization systems — handling millions of AuthN and trillions of AuthZ decisions with ultra-low latency and 99.999% availability

Experience designing cross-region identity and authorization architectures with strong consistency and failover guarantees

Experience with both internal (service-to-service, machine identity) and external (user-facing) AuthN/AuthZ systems at hyperscale

Hands-on experience or strong vision for next-gen auth systems — passwordless, device trust, continuous verification, and AI-driven access policies

Strong knowledge of ABAC, ReBAC, RBAC and policy engines (OPA, Cedar)

Proficiency in Go, Python, or Java

Experience with cloud-native platforms (AWS, GCP, or Azure) and Kubernetes

Proven ability to own technical strategy and influence across organizations

Strong communication skills for both technical and executive audiences

Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.
