This position requires an active U.S. Government Security Clearance at the TS/SCI level with CI polygraph.

Vantor is seeking a Senior Data Scientist who thrives on working with big data and delivering data-centric solutions that drive customer impact. The ideal candidate is a proactive problem-solver who can independently identify analytical needs, develop scalable solutions, and clearly communicate insights to stakeholders. This role requires both technical depth and the ability to operate autonomously in a fast-paced, mission-driven environment. 

This project supports a hard and deeply buried target mission set, providing critical analytic insights to government stakeholders. Success depends on the development of accurate, scalable, and mission-tailored data solutions that enable timely and informed decision-making. The work directly impacts national security objectives by transforming complex data into actionable intelligence in a highly specialized and sensitive domain. 

Responsibilities:

  • This position is fulltime on-site in Reston, VA. 

  • Automate and optimize data extraction, cleaning, processing, and analysis tasks using scripting languages and ETL pipelines. 

  • Process and analyze large-scale, structured and unstructured datasets using big data frameworks (e.g., Spark, Hadoop, or cloud-native equivalents). 

  • Independently conduct end-to-end data science/engineering workflows with minimal supervision, from hypothesis generation to delivery of actionable insights. 

  • Explore opportunities to combine graph technologies, machine learning, generative AI, and large language models to create new analytical capabilities. 

  • Clearly document methodologies and findings in formal written reports and present outcomes to both technical and non-technical audiences. 

  • Design, fine-tune, and implement Large Language Models (LLMs) into workflows to support knowledge management systems, including: 

  • Development of LLM-driven tools to automate summarization, tagging, and retrieval of internal data, reports, and documentation. 

  • Integration of LLMs into workflows to streamline knowledge capture, institutional memory, and information sharing. 

  • Deployment of LLM-based internal assistants to support decision-making and reduce redundant effort. 

  • Translate ambiguous business or customer problems into well-defined analytical approaches, experiments, and measurable outcomes. 

  • Present findings and recommendations through clear visualizations, reports, and presentations. 

  • Mentor junior data scientists and contribute to best practices in data science and analytics. 

  • Partner with engineering teams to operationalize machine learning models in production. 

Minimum Qualifications:

  • Current/active TS/SCI security clearance and be willing and able to obtain CI polygraph. 

  • 10 years of experience in data science, analytics, or a related technical field. 

  • Master’s degree in data science, computer science, engineering, statistics, GIS, or related discipline. Degree can be substituted with an additional 2 years of experience. 

  • Proficient in Python, SQL, and tools/libraries for data analysis, machine learning, and automation. 

  • Demonstrated ability to independently conduct full-cycle data projects, from processing to reporting. 

  • Strong verbal and written communication skills; able to explain complex findings clearly. 

  • Familiarity with foundational LLM/NLP concepts and experience applying pre-trained models (e.g., GPT) for internal automation or data summarization. 

  • Ability to work with minimal supervision and produce logically structured, actionable insights. 

  • Ability to collaborate with business stakeholders to define analytical requirements and deliver data-driven solutions. 

  • Demonstrated experience deploying graph databases or graph-based applications into production environments. 

Preferred Qualifications:

  • Expertise in advanced statistical and machine learning techniques, including NLP and unsupervised learning. 

  • Experience developing or fine-tuning LLMs and integrating them into knowledge systems or workflows. 

  • Strong background with cloud-based platforms (e.g., AWS, Azure, GCP) and scalable data processing tools. 

  • Track record of designing or enhancing knowledge management solutions using AI or LLMs. 

  • Experience building internal tools or bots for search, summarization, or decision support using LLMs. 

  • Awareness of responsible AI practices and ethical considerations in LLM deployment. 

  • Knowledge of MLOps practices and tools (e.g., MLflow, Kubeflow, SageMaker, Vertex AI, or Azure ML). 

  • Experience with big data technologies such as Spark, Databricks, or Hadoop. 

  • Familiarity with generative AI, large language models (LLMs), retrieval-augmented generation (RAG), or AI agent frameworks. 

  • Experience with data visualization tools such as Power BI, Tableau, or Looker. 

  • Knowledge of containerization and orchestration technologies such as Docker and Kubernetes. 

  • Strong understanding of graph data modeling, graph algorithms, and graph query languages such as Cypher, Gremlin, or SPARQL.
