Aptima is a technological leader in the national security industry.
Our mission is to drive the future of national security by engineering scalable solutions that fuse technological innovation with human potential to transform how individuals and teams train, develop, and perform in mission-critical environments.
Our culture is rooted in our core values, which have evolved over time and our employees have embraced: Integrity, Ingenuity, Excellence, Respect, Engagement, Teamwork.
At our core, Aptima researches, develops, and innovates within an area that engineering firms largely ignore, the human component.
To impact the world in meaningful ways, you must bring those innovations to light, and that is precisely what we do.
How You Will Make An Impact
The Senior Data Scientist leads data driven problem solving, including design and technical execution, by applying modern AI/ML techniques in dynamic systems that drive our tech enabled solutions for our Department of War (DoW) customers.
This role combines expertise in translating problem requirements and model selection with applied AI system design and project leadership, serving as a technical lead on multidisciplinary programs and coordinating the work of AI engineers and researchers.
The position emphasizes end-to-end data modeling ownership, hands on interaction with stakeholders, and translation of mission needs into operationally effective capabilities, while contributing to proposals, customer engagements, and internal technical excellence.
Key Responsibilities
Lead the design of ML/AI models, interaction workflows, and recommendation system’s designed for skill selection or staff profiles.
Understand the science that can inform requirements addressing trust, explainability, complexity, and characteristics of modern ML solutions.
Serve as technical lead or task lead on AI and human–AI system development efforts, coordinating work across AI engineers and researchers.
