Northrop Grumman Aeronautics Systems is looking to add a Principal / Sr Principal Systems Engineer - Operations Analysis AI to join our team in El Segundo, CA. The candidate should be a self-starter with familiarity working in an Integrated Product Team (IPT) construct. The selected candidate will perform operational‑analysis studies with a focus on mission data‑flow aggregation, dissemination, and architecture. This individual will be a subject‑matter expert (SME) in mission‑relevant data, its implementation across the enterprise, or the development of AI/ML solutions that accelerate data‑driven decision making in multi‑domain simulation environments. Roles and Responsibilities: Model operational environments and conduct trade‑studies via computer simulation. Perform operational and effectiveness analysis to quantify capability gaps. Create and apply knowledge of Tactics, Techniques, and Procedures (TTPs) to support blue/red kill‑chains across multiple security environments, programs, architectures, and platforms. Provide blue/red tactics and CONOPS modeling, simulation, and analysis in mission‑level models to help achieve long‑term program objectives. Conduct mission‑engineering activities that ensure operational capabilities match delivered system performance through the Systems‑Engineering “V”. Develop, train, and validate AI/ML models (e.g., supervised, unsupervised, reinforcement‑learning, Bayesian) that: Analyze large‑scale data streams for pattern detection, anomaly identification, and predictive insight. Perform data‑compression (e.g., autoencoders, sparse coding, learned codecs) to reduce bandwidth/storage while preserving decision‑critical information. Supply real‑time decision‑support scores for complex, multi‑domain simulations. Automate and accelerate time‑intensive data‑workflow steps such as feature extraction, data‑fusion, and report generation. Design and implement MLOps pipelines (e.g., MLflow, Kubeflow, DVC) that integrate training, validation, versioning, and deployment into existing simulation and analysis toolchains. Leverage high‑performance computing (HPC) and GPU acceleration (CUDA, cuDNN, ROCm) to scale model training and inference for massive data sets. Synthesize stakeholder input, visualize results, and communicate findings to leadership at all levels. There is no remote / hybrid / telework available for this position. Travel up to 25% may be required.

Experience in at least one of the following domains: Research, analysis, and assessment threats to U.S. military operations Vehicle performance analysis Navigation / Position Navigation & Timing (PNT) Survivability, lethality, vulnerability, engagement, or mission‑level analysis Electronic Attack (EA), Electronic Protection (EP), Electronic Countermeasures Red or blue CONOPS and TTPs Data‑science fundamentals experience: data preprocessing, feature engineering, statistical analysis, and model evaluation. Active DoD Secret clearance (with a background investigation within the past 5 years or enrolled into Continuous Evaluation) and ability to obtain and maintain Top Secret Clearance (TS). Ability to obtain and maintain initial and upgraded Special Access Program (SAP) access via Program Access Request process. Preferred Qualifications: Current applicable SAP. Active DoD TS with SCI. Strong communication, interpersonal, and leadership skills, including project/analysis‑lead experience. Physics‑based modeling and simulation using object‑oriented programming (C++, C#, Java, or Python). Demonstrated ability to work in a rapid‑prototyping AI/ML environment. Experience with system‑of‑systems modeling tools (AFSIM, Suppressor, Brawler) and associated integration of AI/ML components. Familiarity with AGILE, MBSE, and system architecture frameworks; ability to embed data‑centric AI/ML deliverables into model‑based development cycles. Operational military background or experience providing insight into realistic mission constraints. Proficiency with version‑control systems and collaborative workflow tools. GPU/parallel programming experience (CUDA, OpenCL, MPI, Dask, Spark) for scaling model training and inference. Hands‑on experience building MLOps pipelines (MLflow, Kubeflow, Airflow, CI/CD for model deployment). Knowledge of explainable AI (XAI) techniques and model interpretability tools (SHAP, LIME, Saliency Maps) to support transparent decision making. Experience with data compression and representation learning (autoencoders, variational autoencoders, transformer‑based codecs) applied to telemetry and sensor streams. Prior work on workflow automation (Python scripting, PowerShell, Bash, RPA tools) that reduces manual data‑processing time. Experience modeling and simulating radars, missiles, integrated air‑defense systems (IADS), air and/or space platforms with AI‑enhanced assessment modules.
