Role brief

dataroles summary, based on the employer's posting.

What you'll do

  • Build and apply qualitative or quantitative methods to examine large datasets, including data with uneven structure and cleanliness
  • Use mathematics, statistics, computing or domain knowledge to find meaning in large datasets and support sound conclusions
  • Turn mission questions about large datasets into technical specifications, then help colleagues interpret the findings
  • Explain complex technical results in terms that nontechnical audiences can follow
  • Assess competing technical approaches with awareness of NSA/CSS collection, processing, storage and analysis capabilities

What you bring

  • You have a relevant bachelor's degree and fifteen years of related experience; an associate degree plus seventeen years may qualify
  • Your degree is in a listed discipline, meets the specified coursework criteria, or is paired with an accredited data science certificate
  • You bring relevant experience in data science, machine learning, advanced analytics or another listed area; more than five areas is preferred
  • You hold a TS/SCI clearance with a polygraph

Who this fits

This senior role suits an experienced data scientist who can work across at least two listed skill areas and explain analysis to nontechnical audiences. The position is near Fort Meade, Maryland, and its location can change to meet client needs.

From the employer

  • Principal Data Scientist

Themis Insight solves difficult business, IT, and analytic problems by addressing the whole problem – not just the symptoms – using interdisciplinary approaches that are both practical and innovative. We provide fresh alternatives to ordinary, mainstream consulting firms through small, highly skilled, and hand-picked teams that can meet clients' needs in any industry. Our broad interdisciplinary understanding allows us to provide the right solution, even if it is from outside the industry or traditionally defined problem space. We bring Public and Private, Civilian and Military expertise to every case.

We are hiring a Principal Data Scientist to work in the Fort Meade, MD vicinity. Position location is subject to change based on central MD client's needs.

Required: TS/SCI with a Polygraph

Employ some combination (2 or more) of the following skill areas:

  1. Foundations: Mathematical, Computational, Statistical
  2. Data Processing: Data management and curation, data description and visualization, workflow and reproducibility
  3. Modeling, Inference, and Prediction: Data modeling and assessment, domain-specific considerations

Devise strategies for extracting meaning and value from large datasets. Make and communicate principled conclusions from data using elements of mathematics, statistics, computer science, and application specific knowledge. Through analytic modeling, statistical analysis, programming, and/or another appropriate scientific method, develop and implement qualitative and quantitative methods for characterizing, exploring, and assessing large datasets in various states of organization, cleanliness, and structure that account for the unique features and limitations inherent in NSA/CSS data holdings. Translate practical mission needs and analytic questions related to large datasets into technical requirements and, conversely, assist others with drawing appropriate conclusions from the analysis of such data. Effectively communicate complex technical information to non-technical audiences. Make informed recommendations regarding competing technical solutions by maintaining awareness of the constantly-shifting NSA/CSS collection, processing, storage and analytic capabilities and limitations.

Individual Capabilities/Experience Required:

  • A Bachelor’s degree and 15 years of relevant experience. An Associate’s degree plus 17 years of relevant experience may be considered for individuals with in-depth experience that is clearly related to the position.
  • Degree must be in Mathematics, Applied Mathematics, Statistics, Applied Statistics, Machine Learning, Data Science, Operations Research, or Computer Science. A degree in a related field (e.g., Computer Information Systems, Engineering), a degree in the physical/hard sciences (e.g. physics, chemistry, biology, social, and life) may be considered if it includes a concentration of coursework (typically 5 or more courses) in advanced mathematics (typically 300 level or higher; such as linear algebra, probability and statistics, machine learning) and/or computer science (e.g., algorithms, programming, data structures, data mining, artificial intelligence). College-level Algebra or other math courses designated as elementary or basic do not count.
  • Note: A broader range of degrees will be considered if accompanied by a Certificate in Data Science from an accredited college/university.
  • Relevant experience must be in designing/implementing machine learning, data science, advanced analytical algorithms, programming (skill in at least one high-level language (e.g. Python) and skill in at least one mid-level language (e.g. C)), data mining, advanced statistical analysis (e.g. statistical foundations of machine learning, statistical approaches to missing data, time series), advanced mathematical foundations (e.g. numerical methods, graph theory), artificial intelligence, workflow and reproducibility, data management and curation, data modeling and assessment (e.g. model selection, evaluation, and sensitivity analysis), experience as a data scientist working to support a single or multiple domain areas, ability to quickly acquire needed expertise on a new domain area, and/or software engineering. Experience in more than five areas is strongly preferred.
