Principal Platform Software Engineer

As a Principal Platform Engineer on the Identity and Access Management (IAM) team, you’ll provide technical leadership for Tier-0, mission-critical identity services powering authentication and authorization at cloud scale. You’ll design highly available and reliable distributed systems, lead complex technical initiatives, and help build the next generation of identity infrastructure for AI and agentic ecosystems. This is a hands-on individual contributor role with broad impact across architecture, engineering, and service operations. Required Technical Skills • Strong programming skills in Java, Go, C++, Python, or a similar language. • Deep understanding of distributed systems, concurrency, fault tolerance, and high-availability architectures. • Significant experience designing and operating large-scale, mission-critical cloud services. • Strong experience with REST APIs, microservices, cloud architectures, CI/CD, and automated testing. • Strong understanding of authentication, authorization, application security, and secure software development. • Experience troubleshooting complex production systems and driving reliability and performance improvements. • Understanding of security and compliance requirements such as FedRAMP and PCI DSS. Preferred Qualifications • Deep experience with Identity and Access Management (IAM) systems. • Experience operating Tier-0 or similarly critical services with stringent availability requirements. • Experience with OCI, AWS, Azure, or GCP. • Experience with observability, SLOs, distributed tracing, and reliability engineering. • Experience with OAuth 2.0, OpenID Connect, SAML, SCIM, JWT, or related identity standards. • Experience with applied cryptography. • Familiarity with emerging identity models for AI agents, machine identities, delegation, and agentic systems. Expectations • Own the technical direction and long-term health of critical IAM capabilities. • Solve complex and ambiguous problems spanning multiple systems and teams. • Make sound architectural decisions balancing security, reliability, scalability, and maintainability. • Drive Tier-0 service availability and reliability through resilient architecture and operational excellence. • Lead complex initiatives from architecture through production operation. • Anticipate technical and operational risks and drive solutions proactively. • Help define identity and authorization architectures for the emerging agentic ecosystem. • Influence technical decisions across teams and mentor other engineers. • Remain hands-on through implementation, prototyping, debugging, and technical reviews. Success Indicators • Delivers secure, highly available IAM systems at significant scale. • Improves the reliability and resilience of mission-critical services. • Drives major technical initiatives across service and team boundaries. • Anticipates and resolves complex architectural and production challenges. • Advances next-generation identity capabilities for AI and agentic workloads. • Raises the technical effectiveness of the broader engineering organization. • Earns trust through strong technical judgment, execution, ownership, and influence.
