AI Engineer

Description: 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.

How You’ll Make an Impact

Operating in the Dayton area and collaborating closely with DoD research customers, you will design, develop, and apply advanced AI and machine learning models to solve complex, mission-critical problems. Whether fine-tuning large language models, building computer vision systems, or integrating multi-modal AI solutions, your work will directly support military readiness and innovation.

You will work hands-on with real-world datasets, implement and optimize models in Python using tools such as PyTorch, TensorFlow, and LangChain, and collaborate with fellow AI researchers to deliver high-quality, production-ready solutions. By combining technical expertise with creative problem solving, you will help drive the next generation of AI capabilities for defense applications.
