Internship Agent Based Modeling Jobs in Texas (NOW HIRING)

ExxonMobil is seeking a highly motivated Postdoctoral Researcher specializing in multimodal knowledge extraction and reasoning. The successful candidate will develop advanced AI methods to extract, integrate, and reason over information from diverse data sources-including text, images, video, time series, and structured data-to support critical business and engineering decisions.

This role is ideal for a recent Ph.D. graduate with expertise in multimodal machine learning, knowledge representation, and reasoning systems. The candidate will work in a collaborative environment to build next-generation AI systems that transform complex, heterogeneous data into actionable insights.

• Develop methods for multimodal data fusion and representation learning across text, visual, spatial, and temporal data.
• Design models for knowledge extraction, including entity recognition, relation extraction, and structured information generation from unstructured and semi-structured data.
• Build reasoning systems that combine neural methods with symbolic or knowledge-based approaches.
• Develop and apply large language model (LLM)-based and multimodal foundation models for knowledge understanding and reasoning.
• Construct and utilize knowledge graphs and structured representations for enhanced reasoning and decision support.
• Enable context-aware inference and decision-making using heterogeneous data sources.
• Evaluate models for accuracy, robustness, and reasoning capability, including explainability where relevant.
• Collaborate with domain experts to translate extracted knowledge into decision-support workflows.
• Implement scalable pipelines using modern ML frameworks and data engineering best practices.
• Communicate findings through technical reports, journal publications, and conference presentations.

• Multimodal machine learning and cross-modal representation learning
• Knowledge extraction from text, images, and sensor data
• Knowledge graphs and graph-based reasoning
• Neural-symbolic AI and hybrid reasoning systems
• Large language models and multimodal foundation models
• Information retrieval, semantic search, and question answering
• Temporal and causal reasoning in complex systems
• Applications to engineering, scientific, and industrial data environments

• Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, or a closely related field, with a focus on multimodal learning, knowledge extraction, or reasoning.
• Demonstrated research experience in multimodal machine learning and/or knowledge-based AI, including one or more of:
  • • Multimodal representation learning
    • Information extraction or natural language understanding
    • Knowledge graphs or structured representations
    • Reasoning systems (neural, symbolic, or hybrid)
• Experience with modern deep learning architectures, including transformers and foundation models.
• Strong programming skills in Python.
• Hands-on experience with machine learning frameworks such as PyTorch, TensorFlow, or JAX.
• Experience working with heterogeneous datasets (text, images, structured data, etc.).
• Strong analytical, problem-solving, and communication skills.
• Ability to work effectively in multidisciplinary teams.

• Experience with multimodal foundation models or large language models (LLMs).
• Familiarity with knowledge graph construction, querying, and reasoning frameworks.
• Experience with retrieval-augmented generation (RAG) or hybrid search systems.
• Background in probabilistic reasoning, causal inference, or uncertainty-aware AI.
• Experience with scalable data pipelines and distributed ML systems.
• Experience applying AI methods to scientific, engineering, or industrial datasets.
• Strong publication record in multimodal AI, NLP, or knowledge-based systems.
• Demonstrated ability to translate research into practical decision-support tools.

This opportunity is for a postdoctoral position expected to last one to three years, subject to annual review and renewal.
