Job description

The OpportunityAs a Senior AI/ML Engineer, you will design, build, and deploy advanced artificial intelligence and machine learning solutions that modernize mission systems and accelerate decision‑making across the national security ecosystem. You will contribute end‑to‑end—spanning data processing, model development, MLOps, and integration of scalable AI capabilities into operational environments.Your work will leverage deep experience with ML‑based NLP, LLMs and generative AI, computer vision, and modern software engineering practices, consistent with the company’s AI/ML engineering role definitions. We value first-principles reasoning and physically interpretable models, so experience developing hybrid systems that combine calibrated sensor models, deterministic algorithms, probabilistic inference, and learned components is particularly desirable. Candidates should be motivated by building systems that are scientifically explainable, empirically validated, and capable of operating robustly across both synthetic and real-world sensing environments. You will partner closely with cross‑functional engineering, mission SMEs, and product teams to deliver production‑grade systems aligned with Booz Allen’s AI modernization approaches.Join us. The world can’t wait.What You'll Do:Design, develop, and implement AI/ML models, including NLP, LLM‑based pipelines, deep learning architectures, and computer vision models, aligned to mission requirementsBuild and optimize scalable data pipelines to support training, evaluation, and continuous improvement of modelsDevelop end‑to‑end production systems including microservices, APIs, automation frameworks, and cloud‑native or edge‑deployed AI servicesIntegrate AI/ML capabilities into operational environments with attention to security, reliability, observability, and performanceConduct model optimization, tuning, versioning, and AB testing to ensure robust mission impactApply modern software engineering patterns, including Python, Java, Scala, or Rust, microservices, and distributed systems as consistent with Booz Allen’s AI/ML engineering frameworksCollaborate with multi‑disciplinary teams to identify mission needs, gather requirements, and define technical approachesPrepare technical documentation, contribute to design reviews, and support accreditation or security processes as required in classified environmentsYou Have:5+ years of experience developing machine learning models, such as NLP, LLM, CV, deep learning, generative AI, or reinforcement learning5+ years of experience developing AI/ML capabilities to operate in a microservice stackExperience developing or maintaining production‑grade APIs, microservices, or distributed systemsExperience with data processing frameworks and scientific computing libraries, such as NumPy, Pandas, PyTorch, TensorFlow, or scikit‑learnExperience designing, configuring, or deploying software systems in operational environmentsExperience with CI/CD tooling, source control, such as GitLab, and containerization technologies, such as Docker, Podman, or KubernetesActive TS/SCI clearance; willingness to take a polygraph examBachelor's degree in a STEM fieldNice If You Have:Experience in GPU programming, including CUDA or RAPIDsExperience with AWS and containerization of models in a classified environmentExperience with LLM orchestration, RAG pipelines, grounding, or hallucination‑mitigation workflowsExperience with MLOps platforms, distributed training, or hybrid cloud environments, such as AWS, Azure, or GCPKnowledge of automated testing tools and model evaluation frameworksMaster’s degree in Computer Science, AI/ML Engineering, Data Science, or related STEM fieldAI/ML, cloud, or solution architecture certificationsClearance:Applicants selected will be subject to a security investigation and may need to meet eligibility requirements for access to classified information; TS/SCI clearance is required.CompensationAt Booz Allen, we celebrate your contributions, provide you with opportunities and choices, and support your total well-being.
