Senior Data Scientist/Engineer

Requisition #: 1355

Job Title: Senior Data Scientist/Engineer

Location: Chantilly, VA

Clearance Level: Active DoD - TS/SCI FSP

Non-Employee Referral Bonus Eligible: $2,000

SUMMARY

You will join a secure, on-site intelligence data-analysis initiative focused on empowering end users to rapidly sift through vast cyber datasets and surface actionable insights. Working alongside cyber subject-matter experts, data engineers, and analysts, the program delivers a next-generation analytics tool that combines natural language processing, entity extraction, and generative AI to accelerate decision making in a highly classified environment.

As a Senior Data Scientist, you will design, develop, and deploy advanced data-science models and workflows within a cross-functional team. You will translate complex requirements into scalable algorithms, collaborate on data-ingestion and parsing tasks, and iteratively refine prototypes to meet end-user needs. Your work will directly inform the core analytics capabilities of the program’s user interface.

JOB DUTIES AND RESPONSIBILITIES

·Lead the end-to-end development of NLP and entity-extraction models tailored for cyber data.

·Prototype and integrate generative AI solutions to automate insight generation.

·Assist with data-engineering tasks, including parsing raw logs and preparing feature sets.

·Collaborate with cyber SMEs to define data-quality standards and validation criteria.

·Translate user stories and requirements into technical specifications and test plans.

·Implement, document, and maintain Python code for reproducible data-science workflows.

·Conduct model performance evaluations and iterate to improve accuracy and scalability.

·Present findings and demos to stakeholders, incorporating feedback into subsequent sprints.
