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.
