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.

ADDITIONAL SKILLS & QUALIFICATIONS

Required Skills

· Strong proficiency in Python and its data-science ecosystem (pandas, scikit-learn, PyTorch/TensorFlow).

Expertise in NLP techniques (e.g., tokenization, named-entity recognition, embedding models).

· Proven ability to implement entity-extraction pipelines.

· Familiarity with generative AI frameworks and experience with machine learning.

· Experience with data-engineering fundamentals (ETL, data cleansing, feature engineering).

· Exceptional verbal and written communication skills; ability to distill complex concepts for non-technical audiences.

· Demonstrated experience working with cyber or security-related datasets.

Preferred Skills

· Experience with big-data platforms (Spark, Hadoop) and stream processing (Kafka).

· Familiarity with cloud-based intelligence-community environments (AWS GovCloud, Azure Government).

· Knowledge of containerization (Docker) and orchestration (Kubernetes).

· Hands-on experience with data-visualization tools (e.g., Plotly, D3.js).

WORKING CONDITIONS
