Junior Data Scientist

Leidos • Alexandria, VA • 19h ago

Description

Are you ready for your next challenge?

Leidos Digital Modernization team is looking for a Junior Data Scientist, who will work closely with a specialized team of data scientists, as well as a larger team of software developers, network engineers, senior investigators, program managers, researchers, and data analysts to design, build, and optimize a Data Science platform to produce and analyze results, disseminate findings, and contribute to data optimization.

What will you do in this role?

Conduct data analysis to support the department's planning and assessment, including Measures of Effectiveness (MOE), Measures of Performance (MOP), and campaign impact evaluations.

Translate complex datasets into clear visuals, dashboards, and narrative reports for planners, leadership, and assessment teams.

Work on small projects analyzing a variety of big data covering cloud, cybersecurity, and network.

Identify trends, anomalies, and engagement patterns across cyber and networks.

Support multiple simultaneous projects and take open-ended or high-level guidance, independently and collaboratively make discoveries that are mission-relevant, and package and deliver the findings to a non-technical audience.

Leverage your strong background in research design, exploratory analysis, quantitative methods, and user interface application design.

Build statistical and machine learning models, conduct natural language processing (NLP), and develop automated solutions for complex business challenges.

Construct and execute complex database search queries across multiple databases using SQL and API interfaces.

Perform web scraping and apply various techniques for processing unstructured data.

Leverage automation and machine learning to manage data, predict scenarios, and make data-driven recommendations.

Leverage technologies, including AWS and Git.

Basic Qualifications:

Must have an active DoD Secret or Top-Secret clearance.

BS in Data Science or Data Analytics and 2+ years of relevant technical experience.

Experience with Python is required.

Strong SQL skills and experience with relational databases and APIs for data extraction are required.

Experience with supervised and unsupervised learning and natural language processing (NLP) is required. Familiarity with NLP libraries and tools (e.g., spaCy, Hugging Face, NLTK, or TensorFlow).

Experience with frequentist statistics, probability, and predictive modeling, along with knowledge of computer science concepts, data architecture, and statistical methods

Come break things (in a good way). Then build them smarter.

We're the tech company everyone calls when things get weird. We don't wear capes (they're a safety hazard), but we do solve high-stakes problems with code, caffeine, and a healthy disregard for "how it's always been done."
