Palantir Technologies

Full-stack Engineer

• We are a software engineering team with expertise in enabling ML models in production.
• We deploy AI models to run in a variety of environments.
• Our customers rely on us for frontier AI capabilities running on hardware they control.
• You will own services end-to-end, and work across the full stack, from inference engines, GPU scheduling to deployment pipelines, observability, and integration with Palantir's platform.
• The goal is to deliver new models and capabilities quickly and continuously.

Software Engineer – Hosted Model Infrastructure

• Building high-performance model serving infrastructure that integrates with security models, hardware constraints, and different inference engines
• Designing intelligent request handling including authentication, rate limiting, concurrency control, and audit logging for multi-tenant model access
• Building and maintaining packaging and deployment pipelines enabling fast, secure, and reliable model rollouts across on-premises and air-gapped environments
• Developing observability for production AI systems to enable easy service monitoring and fast incident triage and resolution
• Debugging complex issues and performance problems throughout the stack, including open source inference engines, container runtimes, and GPU drivers, in environments you cannot always access directly
• Designing and running testing and benchmarking infrastructure that validates model deployments across varying GPU hardware before they reach production
• Working with product teams and customers to understand requirements, debug production issues, and deliver the models and capabilities they need
• Integrating hosted model infrastructure with Palantir's deployment, configuration, and identity systems

Security Engineer

• Own the day-to-day identity security posture across corporate, production, customer, and US Government identity planes
• Drive the rollout of agent identity infrastructure - short-lived credentials, lifecycle bound to a human principal, controlled workload onboarding
• Architect authentication, federation, and authorization systems - including SAML, OIDC, and policy-driven access control models (RBAC, ABAC, policy-as-code) - across workforce and workload identity
• Scale non-human identity patterns across service, workload, and agent populations - short-lived credentials, mTLS, identity-based networking
• Drive adoption of just-in-time access patterns across the identity program, partnering with platform and engineering teams on governance rollout and policy enforcement
• Lead identity threat modeling on a regular cadence; publish findings and track remediation
• Serve as a primary security reviewer on identity architecture decisions and cross-team RFCs
• Research and drive adoption of emerging identity security primitives and standards in partnership with Security Engineers across InfoSec
• Partner with engineering teams across Palantir to reduce the attack surface of identity integrations at scale

Senior Identity Security Engineer

• Track and review tax payments, shadow payroll, and tax equalization across multiple countries
• Initiate expat-related tax and payroll payment requests; review payroll outputs for accurate and compliant reporting.
• Verify mobility and tax cost reporting for accruals and cross charges
• Maintain relationships with external tax service providers to ensure our employees receive best-in-class support and advice
• Build strong relationships with internal stakeholders across all levels of the business to drive projects and initiatives related to mobility processes and internal systems
• Identify opportunities to integrate AI and automation into mobility tax workflows — from data gathering and reconciliation to vendor communication and compliance tracking
• Partner with Palantir's internal AI and data teams to help build and refine tools that improve the speed, accuracy, and scalability of global mobility operations
