Platform Engineer - Identity Infrastructure

A World-Changing Company

Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.The Role

As a Platform Engineer on Palantir's Identity Platform team, you will design, build, and operate secure-by-design identity infrastructure and tooling. You will make identity governance and access management easier and more secure to implement for Palantirians and customers worldwide. As part of Palantir's best-in-class Information Security organization, you will research, implement, and scale innovative solutions that help Palantir stay ahead of a dynamic threat <landscape.You> will help the team build the next-generation identity platform that treats agents and workload identities as first-class principals: the access graph that makes entitlements legible, the policy engine that makes authorization enforceable and auditable, and the token-issuance layer that keeps access short-lived, scoped, and least-privilege by default. Your work will shape the arc of these components from design to <production.You> will join the high-performing Identity Platform team, engineers who are passionate about delivering identity outcomes at scale that reduce risk and friction. The team builds and operates the identity platforms that serve both corporate and production (customer-facing) infrastructure, and the paved-road tooling and secure baselines that teams across Palantir deploy on. Your goal will be to make the secure path the easy path. Your work will directly strengthen the identity substrate beneath Palantir's most critical deployments, from a globally distributed workforce to regulated and air-gapped environments.

Core Responsibilities

Develop automation and tooling for corporate and customer-facing identity platforms

Build, secure, and manage geo-redundant containerized services (EKS and ECS) in AWS and Azure

Scale the implementation of Single Sign-On (SSO) integrations across multiple Entra ID tenants using infrastructure-as-code frameworks

Build tooling to standardize and scale operational workflows across AWS, Azure, and Google Cloud Platform (GCP)

Extend the identity platform to non-human identities, treating workloads and AI agents as first-class principals with scoped, short-lived credentials

Build the governance layer: an access graph that makes entitlements legible and a policy engine that makes authorization decisions enforceable and auditable

Design token-issuance and federation flows that make least-privilege, ephemeral access the default

Research and drive adoption of emerging authentication and session security standards (such as device-bound session credentials and continuous access evaluation) in collaboration with Security Engineers

Pressure-test designs and partner with Identity Security Engineers to threat model implementations before they ship

Partner with Security Compliance Engineers to build services that reduce the cost and complexity of compliance enforcement

What We Value

Technical proficiency in identity protocols (SAML, OIDC, OAuth 2.0, LDAP, Kerberos, FIDO2, WebAuthn)

Experience managing identities and governance workflows on platforms such as Entra ID, Keycloak, AWS Cognito, or Okta

Experience with policy engines and authorization-as-code, and with relationship-based access modeling or entitlement graph design

Experience with token issuance and federation, including OAuth 2.0 token exchange, short-lived credentials, and workload identity federation

Non-human identity experience: workload and machine identity (service-to-service authentication, mTLS, workload attestation), plus interest in agentic identity (agents as principals, delegation and on-behalf-of flows, and attribution across a delegation chain)

What We Require

• 3+ years of experience in Site Reliability Engineering (SRE), DevOps, software engineering, or an equivalent discipline, with a strong passion for security
• Experience deploying and operating containerized services (EKS, ECS, or similar) in AWS, Azure, or Google Cloud
• Experience building and operating production services or APIs, not only automation scripts
• Expert-level proficiency in a language such as Go (preferred), Python, or TypeScript
• Experience with infrastructure-as-code (Terraform, Helm, CloudFormation, or similar)
• An active TS/SCI security clearance, or eligibility and willingness to obtain one
