Job Description

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.

Job Responsibility

  • 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

Requirements

  • 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

Nice to have

  • Working knowledge of networking fundamentals, experience with CNIs or cloud networking infrastructure preferred
  • Experience designing, building, and operating high-scale observability or infrastructure systems

What we offer

  • Employees (and their eligible dependents) can enroll in medical, dental, and vision insurance as well as voluntary life insurance
  • Employees are automatically covered by Palantir’s basic life, AD&D and disability insurance
  • Commuter benefits
  • Relocation assistance
  • Take what you need paid time off, not accrual based
  • 2 weeks paid time off built into the end of each year (subject to team and business needs)
  • 10 paid holidays throughout the calendar year
  • Supportive leave of absence program including time off for military service and medical events
  • Paid leave for new parents and subsidized back-up care for all parents
  • Fertility and family building benefits including but not limited to adoption, surrogacy, and preservation
  • Stipend to help with expenses that come with a new child
  • Employees can enroll in Palantir’s 401k plan
