Software Engineer (Agentic Systems & Integration), Advanced Capabilities

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years. ABOUT THE JOB We're looking for a highly driven software engineer to help make our simulation capabilities accessible to both humans and LLM agents. You will architect and deliver systems that enable Anduril's Advanced Capabilities team to define and explore how fleets of heterogeneous autonomous systems operate alongside humans in complex and contested environments. Within a multidisciplinary team of engineers you'll be the primary owner of backend services and agent integration, sitting at the intersection of simulation infrastructure, agent tooling, and user-facing products. If you're an engineer who thrives on solving hard problems and wants to build software that redefines the future of defence, this is your opportunity. WHAT YOU'LL DO Design and build the agent integration layer: tool schemas, context management, retrieval over simulation state, and guardrails that let LLM agents reliably author scenarios, task entities, generate visualisations, and perform real-time analysis across our wargaming applications Architect APIs and service contracts (gRPC/protobuf) with both human and machine consumers in mind Build robust, high-performance backend services in Go that coordinate with downstream components in C++ and Rust handling scenario execution, physics modeling, and autonomy Deploy and maintain services on Kubernetes infrastructure, ensuring reliability and performance Collaborate closely with game engineers, robotics engineers, autonomy specialists, and war fighters to translate technical capabilities into reliable, performant features Identify bottlenecks and optimise features across the stack, from database queries to model inference Identify and close the gaps between what our systems can do and what agents can access REQUIRED QUALIFICATIONS Bachelor's degree in Computer Science or related field; or equivalent industry experience Hands-on experience with at least some of: LLM function calling, tool use, RAG, agent orchestration, MCP. Deep interest in the rest. Strong proficiency in a garbage collected language (we use Go and Python) Comfortable reading and working with C++ and Rust codebases Experience building and deploying distributed systems with containerization and orchestration platforms (K8s) Understanding of databases, data modeling, and system architecture Familiarity with gRPC/protobuf or similar RPC technologies A bias for action, extreme ownership, and the drive to see projects through from concept to production Comfortable making decisions with incomplete information and shipping incrementally Eligible to obtain and maintain an active UKSV Security Clearance PREFERRED QUALIFICATIONS Experience shipping production agentic systems (not just prototypes) Experience in defence, aerospace, robotics, or other real-time C2 systems The salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations. Highly competitive equity grants are included in the majority of full time offers; and are considered part of Anduril's total compensation package.
