Senior AI Infrastructure Engineer

About The Job: We are looking for a Senior AI Infrastructure Engineer to build, scale, and optimize the end-to-end machine learning platform that powers Anduril's autonomous systems. In this role, you will own critical components of our ML platform and MLOps tooling. You will build and operate the infrastructure required to train, evaluate, host, and serve complex AI models (including LLMs, computer vision, and RL agents) across cloud environments and air-gapped, edge-deployed networks. Working closely with AI Research Scientists and Platform Engineers, you will eliminate friction in model development, optimize hardware utilization, and ensure robust delivery of models into safety-critical operational environments.

What You'll Do: Build, optimize, and maintain scalable training, orchestration, and experimentation infrastructure to accelerate state-of-the-art model development. Identify and resolve bottlenecks in the ML lifecycle by developing tooling for experiment tracking, automated profiling, and hyperparameter tuning. Implement and scale robust data pipelines (ETL) to process multi-modal data (video feeds, radar, flight telemetry, and simulation logs) captured from physical assets and test sites. Deploy high-throughput, low-latency model serving frameworks optimized for both cloud environments and resource-constrained, air-gapped tactical edge hardware. Develop robust CI/CD pipelines for ML models, including automated regression testing, validation benchmarks, and safe rollout/rollback strategies. Implement pipelines for model evaluation, validation, and reinforcement learning alignment loops (RLHF/DPO) to ensure predictability and safety in mission-critical deployments. Partner with AI Researchers and Computer Vision engineers to translate modeling requirements into scalable, reusable infrastructure. Mentor peers, conduct thorough design and code reviews, and champion engineering best practices across the team. Required

Qualifications: 5+ years of software engineering experience with demonstrated success in building and operating production-scale machine learning infrastructure or distributed systems. Proficiency in Python, Go, or C++, with a strong grasp of software engineering fundamentals, systems design, and concurrent programming. Hands-on experience with container orchestration (Docker, Kubernetes) and distributed training frameworks (e.g., PyTorch Distributed, Ray, Slurm, or Megatron-LM).Experience building and maintaining distributed data pipelines handling large-scale unstructured or multi-modal datasets. Track record of owning projects end-to-end—from technical design to production deployment and operational monitoring. Eligible to obtain and maintain an active U.S. Top Secret security clearance. Preferred

Qualifications: Experience deploying ML infrastructure, model serving, or artifacts in secure, air-gapped, or regulated environments (e.g., IL5/IL6, GovCloud).Hands-on experience profiling GPU/accelerator workloads, resolving hardware/network bottlenecks, and optimizing compute utilization. Experience supporting workloads for Large Language Models, Generative AI, or Reinforcement Learning (RL) pipelines. Experience with multi-tenant cluster management, including fair scheduling, GPU slicing, and quota enforcement. Familiarity with production ML observability frameworks, including data drift detection and automated evaluation pipelines. US Salary Range $191,000 - $253,000 USD
