HRL Laboratories, LLC is seeking a Graph Machine Learning Scientist to Lead and contribute to cutting‑edge research in graph computing and graph machine learning (GML).

• Design, develop, and evaluate algorithms for graph representation learning, reasoning, and analytics on dynamic, heterogeneous, and large-scale graphs.
• Apply GML to high-impact domains such as cybersecurity, finance, social science, material science, and intelligent systems.
• Integrate GML with foundation models (e.g., large language models/LLMs, multimodal models) for tasks like knowledge graph reasoning, graph‑augmented retrieval, and trustworthy decision support.
• Translate research insights into deployable prototypes and production‑level software.
• Author technical publications, invention disclosures, and research presentations for internal and external stakeholders, and support proposal and business development activities.

• Hands‑on experience with graph mining, graph matching, geometric deep learning, and applied GML problems.
• Proficiency in Python (preferred) or another major programming language (e.g., C++, Java) and deep learning libraries and frameworks (e.g., PyTorch Geometric, DGL).
• Experience with knowledge graphs, ontologies, graph schemas (e.g., RDF, LPG), graph databases (e.g., Neo4J, Tiger Graph), and query languages (e.g., Cypher, SPARQL).
• Experience with large‑scale data processing and distributed systems (e.g., Ray, Spark), and optionally with real‑time streaming pipelines or online learning pipelines.
• Experience with bridging GML with NLP, computer vision, multi‑modal AI, and agent‑based systems.
• Track record of peer‑reviewed publications in premier AI/ML venues (e.g., NeurIPS, ICLR, KDD,(Use the "Apply for this Job" box below). AAAI, ICML, SIGMOD).

• Graph neural networks (GNNs) and geometric deep learning.
• Temporal/dynamic graph learning and event forecasting.
• Subgraph matching and pattern discovery in large‑scale graphs.
• Heterogeneous, multi‑relational, and knowledge graphs.
• Resource‑efficient, edge, or federated graph learning.
• Graph‑based reasoning, multi‑hop inference, and neuro‑symbolic AI.
• Graph foundation models and multimodal graph learning.
• Graph‑augmented LLMs and agent‑based reasoning on graphs.
• Graph‑based program analysis and optimization.
• Trustworthy AI, model interpretability, and explainability.
