Anduril Industries is looking to transform U.S. and allied military capabilities with advanced technology by bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

Requirements

  • 12+ years of software engineering experience in a fast-paced environment (startup or high-velocity delivery context).
  • Hands-on experience building production systems (expect to code ~30% of your time). We use Python and TypeScript.
  • Strong experience building platforms, infrastructure tooling or distributed services that support other engineering teams.
  • Deep architectural knowledge: distributed systems, service architecture, APIs, deployment pipelines, observability, reliability.
  • Proven experience in data modeling and API design across domains.
  • Familiarity building or integrating AI/agent systems, working with LLMs, conversational UI/UX, or autonomous workflows.
  • Experience with high-scale distributed systems (multi-region cloud or multi-cluster), service-oriented architecture.

Responsibilities

  • Define and lead the technical roadmap for PlatformOS that includes building core infrastructure, service templates, CI/CD pipelines, deployment tooling, observability/monitoring, guardrails, agent platform, chat UI/LLM integration.
  • Architect, design and develop complex distributed services, tooling and APIs that empower other engineering teams to ship safely and quickly.
  • Integrate PlatformOS capabilities into a cohesive experience across product and platform teams and evolve data-modeling strategies across multiple domains.
  • Co-Lead the development of the agent platform: manage and host large-language models (LLMs), build chat interfaces (OpenWebUI-based), integrate autonomous workflows, and provide developer/self-service tooling.
  • Standardize and unify PlatformOS’s APIs under a cohesive, scalable platform API strategy. Own platform observability, product analytics frameworks, event streaming, schema registries and audit-logging.
  • Lead by example. Apply modern software engineering practices (automated testing, blue/green/canary deployments, infrastructure as code, telemetry, reliability)
  • Mentor and coach engineers, establish shared ownership models (remove single points of failure), improve review practices, accelerate velocity while preserving correctness.

Other

  • U.S. Person status (due to export-control / DoD environment)
  • Excellent communication skills, able to influence senior stakeholders, translate ambiguous requirements and build cross-team alignment.
  • Culture fit: bias for action, low ego, able to make pragmatic trade-offs in ambiguous/fast-paced settings (consistent with Anduril culture).
  • Highly competitive equity grants are included in the majority of full time offers; and are considered part of Anduril's total compensation package.
  • Top-tier benefits for full-time employees, including: Healthcare Benefits, Income Protection, Generous time off, Family Planning & Parenting Support, Mental Health Resources
