With extensive experience in designing, building, and deploying sophisticated data solutions, you excel at transforming raw, unstructured data into structured analytical products that inform decision-making. You lead internal data efforts—from rigorous data cleaning to impactful data visualizations—and effectively present data findings to clients. You are an analyst at heart, possessing the curiosity and acumen to know when to ask the right questions of data and what questions will drive meaningful insights. You understand that the most powerful analytical work bridges computational methods with deep understanding of the social, political, and information dynamics that generate the data in the first place. Responsibilities • Applied Data Science & Solution Implementation: • Design, develop, and deploy scalable, production-ready data science solutions that align with business and project goals. • Leverage AI, machine learning, and advanced statistical techniques to extract insights from complex, large-scale, or unstructured datasets. • Apply techniques such as classification models, clustering algorithms, and other AI methods to drive discovery and inform decision-making. • Design and implement codebook-driven analytical frameworks that translate qualitative research questions into reproducible computational workflows. • Build and iterate on applied models tailored to project and client needs. • Translate analytical findings into actionable recommendations, delivering measurable impact for both internal and external stakeholders. • Provide direct support to the Engineering team as needed to implement solutions. • Applied AI & Automated Workflows: • Design and refine prompts, LLM chains, and agentic AI workflows that automate analytical tasks such as content classification, thematic coding, entity extraction, and structured summarization at scale. • Build and evaluate automated analytical products and pipelines that integrate large language models into repeatable, production-grade workflows with appropriate quality controls. • Experiment with emerging AI techniques—including retrieval-augmented generation (RAG), multi-step reasoning chains, and tool-using agents—to extend the company's analytical capabilities and accelerate delivery. • Data Preparation, Cleaning & Visualization: • Write and maintain efficient, reproducible data pipelines using Python, R, SQL, or similar tools. • Perform complex data cleaning, transformation, and wrangling to ensure high-quality analytical output. • Create compelling dashboards and visualizations using Tableau, Superset, or other tools to communicate insights to both clients and internal teams. • Analytical Framework Design & Research: • Contribute to the design, refinement, and validation of analytical frameworks that structure how the company assesses complex information environments. • Bridge social science theory and computational practice, ensuring that analytical products are methodologically sound and defensible. • Cross-Team Collaboration, Client Engagement & Business Development: • Collaborate with engineering and product teams to build integrated analytical solutions supporting the company's Narrative Analytics approach. • Partner closely with engineering to translate data science requirements into scalable, production-ready tools and pipelines. • Contribute to data architecture decisions, tool selection, and infrastructure development to ensure alignment between analytics and engineering capabilities. • Present data findings to clients with clear communication and actionable recommendations. • Contribute to business development efforts requiring data science expertise, including writing technical sections of proposals, white papers, and concept notes. • Leadership & Internal Data Initiatives: • Lead improvements to internal data science workflows, methodologies, and quality assurance processes. • Mentor junior team members and interns, promote technical upskilling, and foster open discussion of best practices and emerging techniques in NLP, ML, and computational social science. • Contribute to the development and maintenance of shared analytical assets such as codebooks, scoring frameworks, and model evaluation protocols. • Collaboration & Professional Conduct: • Demonstrate ownership, professionalism, and timely follow-through in all responsibilities and communications. • Thrive in a fast-paced, dynamic environment by adapting to shifting priorities and proactively identifying opportunities to improve processes and analytic contributions. • Communicate technical insights clearly and translate complex data science needs into actionable guidance for both technical and cross-functional teams. • Foster collaboration across teams with openness to feedback, respect for diverse expertise, and a commitment to continuous learning. Requirements • Eligibility & Security: • Must be eligible to work on US Government contracts. • Existing security clearance (SECRET or higher) is a plus. • Bachelor's or advanced degree (master's or Ph.D.) in Data Science, Computer Science, Statistics, Mathematics, Computational Social Science, or a related field. • Experience requirements: Bachelor's degree and 5+ years of relevant experience (or advanced degree and 3+ years of experience). • Professional Experience: • 2+ years of proven experience in data science, with a strong track record of driving significant business impact through applied analytics. • Demonstrated experience working with text-as-data, including media, social media, or open-source text corpora. • Technical Expertise: • Proficiency in Python and/or R for data analysis, modeling, and machine learning. • Strong SQL skills for data extraction, transformation, and integrity assurance. • Experience with NLP techniques including text classification, topic modeling, sentiment analysis, embedding-based methods, and transformer architectures. • Experience with statistical and predictive modeling techniques such as support vector machines, random forests, and classification models. • Demonstrated familiarity with the application and use of large language models (LLMs), including prompt engineering, structured output design, and integrating language models into applied analytical workflows. • Familiarity with modern data tools and data lake architectures supporting scalable, data-driven solutions. • Skilled in building insightful visualizations using tools like Tableau, Superset, Power BI, or Looker. • Interpersonal Skills: • Exceptional ability to communicate complex technical concepts to both technical and non-technical audiences. • Effective working both independently and in cross-functional teams, with a collaborative and solution-oriented mindset. Ideal Candidates The strongest candidates will bring experience designing or implementing structured content analysis frameworks or structured analytical methodologies for text data, along with familiarity with information environment assessment, strategic communication analysis, or media landscape monitoring. They will have built ML pipelines that include human-in-the-loop validation, analyst review steps, or active learning workflows, and will have exposure to computational social science research methods such as causal inference, network analysis, or computational text analysis beyond keyword search—including techniques like stance detection, narrative framing, and document similarity. Experience designing LLM chains, agentic AI systems, or automated analytical products that move beyond one-off prompting into repeatable, quality-controlled workflows is highly valued. Above all, ideal candidates will have a track record of translating social science research questions into scalable computational approaches.
