Job details

Principal Engineer, PlatformOS

Anduril Industries builds advanced defense technology and Lattice OS, an AI-powered command-and-control platform. The PlatformOS team provides the core infrastructure, developer platforms, CI/CD, observability, and an agent/LLM platform that enable product teams to ship safely and quickly. Anduril is seeking a Principal Engineer to define the technical roadmap, architect distributed services, lead the agent/LLM platform, and drive a platform-led engineering culture.

Skills

  • 12+ years building production software in fast-paced environments
  • Hands-on coding (expected ~30% of time) using Python and TypeScript
  • Designing and operating platform/infrastructure tooling and distributed services
  • Deep knowledge of APIs, data modeling, event streaming, and schema design
  • Experience with CI/CD, IaC, deployment strategies, and observability/monitoring
  • Familiarity building or integrating LLMs, conversational UIs, and autonomous workflows
  • Strong cross-team communication and stakeholder influence
  • U.S. Person status (export-control/DoD requirement)

Responsibilities

  • Define and own the technical roadmap for PlatformOS (infrastructure, templates, CI/CD, observability, guardrails, agent platform).
  • Architect, design, and implement complex distributed services, tooling and APIs that other teams consume.
  • Co-lead the agent platform: host/manage LLMs, build chat UI, integrate autonomous workflows and developer tooling.
  • Standardize platform APIs, event streaming, schema registries, audit logging, and product analytics frameworks.
  • Drive platform observability, telemetry, reliability, and modern deployment practices (blue/green, canary).
  • Partner with cross-product service teams to remove friction, build consensus, and ensure platform adoption.
  • Mentor engineers, promote shared ownership, improve code review and delivery practices, and grow engineering culture.

Education

  • Bachelor’s degree in Computer Science, Engineering, or equivalent experience preferred
  • Advanced degree (MS/PhD) helpful but not required
  • Relevant continuing education or certifications in cloud/platform technologies a plus

Benefits

  • Comprehensive medical, dental, and vision (U.S. roles)
  • Company-covered life and disability insurance; mental health resources and coaching
  • Generous PTO with December holiday hiatus, caregiver and wellness leave
  • Family planning support (IVF, adoption, preservation) and parenting resources
  • 401(k)/retirement plans (US) with options; region-specific pension/superannuation
  • Professional development reimbursement, commuter benefits, and relocation assistance
  • Highly competitive equity grants typically included in full-time offers
