Data Scientist

Summary and Description We are seeking a Data Scientist to contribute to and help lead the data science efforts for a cutting-edge investigative platform used by thousands of external users. The platform serves as an essential tool for investigators and leverages machine learning, computer vision, natural language processing (NLP), embeddings, large language models (LLMs), multimodal large language models (MLLMs), and statistical analysis to process large-scale unstructured image, text, and video data.   As a Data Scientist, you will be responsible for selecting, developing, fine-tuning, evaluating, and optimizing machine learning models for scalable production environments. This includes determining when to use off-the-shelf models versus custom or fine-tuned approaches, making sound trade-offs across performance, interpretability, latency, cost, and scalability, and helping guide models from research into deployment. You will collaborate closely with a cross-functional team of DevOps engineers, software developers, data engineers, product managers, and client stakeholders to enhance the platform’s capabilities for its investigator user base.   About the role: This role is ideal for a mission-driven individual who thrives in a dynamic and ambiguous environment, enjoys solving complex data challenges, communicates clearly with both technical and non-technical stakeholders, and is passionate about building innovative, responsible AI solutions to support investigators in sensitive, real-world contexts.   Develop, evaluate, fine-tune, and optimize predictive models and machine learning solutions for unstructured text   and   image .   Select and adapt off-the-shelf models or build custom solutions for production use, including traditional ML, deep learning, LLMs, and multimodal models .   Make informed recommendations on model strategy and development approaches, balancing trade-offs such as accuracy, interpretability, latency, operational complexity, cost, and scalability   Collaborate with engineering and research teams to design, build, deploy, monitor, and maintain scalable predictive systems in production   Apply statistical methods, NLP, computer vision, embeddings, and other modern AI/ML techniques to extract insights and improve platform performance   Research and experiment with state-of-the-art AI/ML methodologies and identify practical opportunities to apply them within the platform   Guide data pipeline architecture from a data science perspective, with a focus on robustness, scalability, reproducibility, and alignment with AWS and broader data engineering practices   Help define how models should be developed, evaluated, operationalized, and monitored in production   Ensure ML solutions are developed and applied responsibly, with careful attention to ethical and practical considerations in sensitive investigative contexts   Identify and integrate additional data sources to enhance investigative capabilities   Contribute directly to product development by working closely with product and client stakeholders to refine requirements, communicate findings, and deploy solutions   Provide thought leadership on emerging data science trends and opportunities for growth   Participate in a rotating on-call schedule to address critical emergencies and help ensure model availability   About You     You’re a great fit for this role if you have:    3+ years of experience in data science, machine learning, or applied AI, including selecting, building, fine-tuning, and deploying models for scalable production environments   Bachelor’s degree in   a quantitative field   such as Statistics, Computer Science, Mathematics, Physical/Biological Sciences, GIS, or a related   technical   discipline   Experience working with both off-the-shelf and custom or fine-tuned models across traditional ML, deep learning, and LLM-based systems   Strong command of Python and common data science and machine learning libraries   Hands-on experience with modern ML/AI techniques, including LLMs, MLLMs, NLP, embeddings, and related approaches   Strong understanding of machine learning, computer vision, NLP, and statistical methodologies   Experience working with large-scale structured and unstructured data   Demonstrated ability to make informed trade-offs regarding model selection, implementation, evaluation, and deployment   Ability to recommend how models should be developed and operationalized in collaboration with engineering and product teams   Familiarity with AWS, data pipelines, and data engineering practices   Hands-on experience with Bash, SQL, and Docker   Strong understanding of the ethical and practical considerations involved in applying ML methods in sensitive contexts   Ability to take ownership of technical design decisions and ensure alignment with customer and product needs   Comfort working in an ambiguous environment with shifting priorities   Ability to communicate clearly with both technical and non-technical stakeholders   Strong planning, organizational, and time management skills   Team-oriented mindset with the ability to work independently, take initiative, and collaborate cross-functionally   Ability to obtain and maintain a U.S. national security clearance. U.S. citizenship is essential to comply with the government contract, agency, or federal government requirements. #LI-SW1 What’s in it For You?
