We build AI systems that determine how logistics decisions are made — not just how they're executed. From factory to foxhole, we operate at the layer where data becomes decisions, and decisions make the advantage. ### What You'll Do In this role, you will build the systems that move a model out of a notebook and into the hands of a planner. Sometimes, that means deploying to an air-gapped rack in a tent instead of a VPC. You will own the path from training run to deployed capability: the infrastructure it runs on, the release process that ships it, the evaluation harness that proves it works, and the telemetry that tells us when it stops working. Our AI/ML team works across retrieval-grounded systems for doctrine and logistics data, document and feature extraction, military symbol recognition, optimization and movement models, and an LLM agent platform. This role underpins that work: building the infrastructure, release processes, and evaluation systems that make it shippable and keep it honest in production. You will have plenty of room to shape how we build it. ### Training & Serving Infrastructure Own model training, fine-tuning, and batch inference infrastructure across AWS (SageMaker, EKS) and on-premises GPU hardware. Stand up and tune LLM inference serving: vLLM-class stacks, quantization, continuous batching, KV-cache and throughput sizing. Make the hosted-vs-local call with numbers behind it. Build for DDIL: local inference with configurable fallback, degraded-mode behavior, and sane resource envelopes on hardware we do not get to choose. ### Release & Reproducibility Build CI/CD for models and pipelines: versioned datasets, a model registry, promotion gates, and rollback that actually works under pressure. Own infrastructure as code, containerization, and GitOps deployment across environments ranging from a dev cluster to a disconnected enclave. Make reproducibility a hard requirement. Any result we put in front of a customer or evaluator must be reproducible from a commit and dataset version. ### Evaluation & Observability Build and own the evaluation harness: regression suites for retrieval and extraction pipelines, LLM-as-judge pipelines with measured judge-human agreement, and adversarial and held-out sets. Instrument production for drift, latency, cost, retrieval quality, and failure modes, including quiet ones such as a retrieval miss that produces a fluent but wrong answer. Make our metrics defensible to external test and evaluation reviewers. “We think it’s good” is not a deliverable. ### Data & Pipeline Ownership Own ingestion, versioning, and lineage for logistics and doctrinal data drawn from a heterogeneous set of authoritative sources. Build and operate embedding and feature pipelines, incremental indexing, and the unglamorous systems that keep a retrieval index fresh. Build the human-in-the-loop infrastructure: confidence-scored routing, review queues, and feedback capture that improves the next model. ### Secure & Accredited Deployment Deploy and operate ML systems in IL5 and IL6 environments, including air-gapped or restricted-network enclaves. Build the release, observability, artifact-management, and incident-response workflows those environments require. Support ATO and continuous-authorization work with implementation evidence tied to applicable security controls (NIST SP 800-171, NIST SP 800-53 Rev. 5, CMMC Level 2, FIPS 140-3, and RMF/eMASS). Handle CUI and classified data correctly without being asked twice. ### What We’re Looking For ### Strong Platform & Infrastructure Skills 5+ years in MLOps, ML platform, or infrastructure engineering, including meaningful time working on systems with real users. Strong Python skills and comfort in a production codebase, not just notebooks. Deep Kubernetes and containerization experience, plus infrastructure as code. Production experience with AWS ML/Azure infrastructure (SageMaker, EKS, or equivalent). --- Data: alder (https://alderhq.app).
