Who We
Are

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.

Operating in the Dayton area and collaborating closely with Department of War (DoW) research customers, you will design, develop, deploy, and sustain advanced AI‑enabled software systems that solve complex, mission‑critical problems. You will work across the full lifecycle—from prototyping and fine‑tuning AI models to engineering scalable applications and deploying production‑ready solutions into operational environments. Whether building large language model applications, computer vision pipelines, multimodal AI systems, or agentic workflows, your work will directly support military readiness and innovation.

In this role, you will bridge AI research and software engineering by transforming cutting‑edge algorithms into robust, maintainable, and deployable systems. You will work hands‑on with real‑world datasets, build backend services and APIs, integrate AI models into software architectures, and collaborate closely with researchers, data scientists, and software engineers to deliver high‑quality operational capabilities. By combining strong AI expertise with software engineering best practices, you will help advance the next generation of intelligent systems for defense applications.
