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 Senior Software Engineer on Network Infrastructure you will be joining a team whose mission is to make a highly dynamic and intricate Kubernetes networking tech stack a pleasure to interact with, in addition to being legible, robust and secure.

The Network Infrastructure team owns the tech responsible for north-south and east-west traffic flows across 100s of zero-trust K8s clusters running variable workloads. The team solves the novel technical challenges emergent at the intersection of scale, usability and security: enabling dynamic control over ephemeral infrastructure (10s of thousands of firewall rules targeting 1000s of short-lived pods) across multiple compliance regimes, using CNCF tools like envoy, cilium with K8s controllers to operate them.

In this role, you will be working in one of the most technically challenging spaces at Palantir.

Core Responsibilities
  • Drive Palantir’s infrastructure strategy while grappling with the needs of your team’s diverse customer base
  • Build the APIs through which both internal and external software developers interact with network infrastructure
  • Deeply understand and leverage K8s networking primitives and the broader OSS ecosystem around K8s
  • Champion a long-term roadmap to reduce operational burden, ensure scalability, reduce risk, and strive for transformative impact
What We Value
  • Clear and concise verbal and written communications with a focus on impact and ability to articulate the value your work provides
  • Ability to engage stakeholders and ensure timely delivery to address core business needs
  • Passion for designing thoughtful and robust APIs
  • Deep familiarity with K8s, and the broader ecosystem of software around K8s
  • Working knowledge of networking fundamentals, experience with CNIs or cloud networking infrastructure preferred
  • Experience designing, building, and operating high-scale observability or infrastructure systems
  • Strong coding skills in Go, Java, or equivalent
What We Require
  • 3+ years of professional software development experience
  • 1+ years of experience contributing to the system design or architecture (architecture, design patterns, reliability and scaling) of new and existing systems
  • Bachelor's degree in Computer Science or equivalent
