* Contribute to the development of innovative AI-enabled capabilities across domains such as human-AI teaming, synthetic media analysis, influence modeling, and agent-based systems.

Prototype System Architecture

* Lead the design and implementation of software architectures for complex research prototypes, including APIs, data pipelines, model integration layers, and evaluation frameworks.

* Build modular and extensible systems that allow Aptima researchers and external collaborators to rapidly integrate new models, analytics, and experimental capabilities.

* Balance rapid research iteration with maintainable and well-structured engineering practices.

* Support experimentation with emerging AI approaches including agentic systems and multimodal analytics.

AI Systems Development and Deployment

* Implement and integrate machine learning and AI models within experimental systems and research testbeds to support internal evaluation and integration with external systems for large-scale evaluation experiments and demonstrations.

* Develop workflows that support model training, evaluation, experimentation, and comparative analysis.

* Develop containerized research environments using tools such as Docker to support reproducible experimentation.

* Assist in preparing prototype systems for technology demonstrations with sponsors such as DARPA, DoW laboratories, and operational partners.

Technical Leadership & Collaboration

* Provide technical leadership on R&D projects, helping shape system architectures and technical approaches, and collaborating with engineering leadership across the company.

* Work across multidisciplinary teams including AI researchers, cognitive scientists, and engineers.

* Mentor junior engineers and research staff on software architecture, engineering practices, and scalable research infrastructure.

* Participate in customer engagements, technical reviews, demonstrations, and collaborative research activities.

*Bachelor's or Master's degree in Computer Science, Engineering, Data Science, AI/ML, or a related technical field (or equivalent practical experience).

* Ability to obtain and maintain a U.S. Government security clearance.

* 6+ years of professional software engineering experience developing complex technical systems.

* Strong proficiency in Python and modern software engineering practices.

* Experience building complex research prototypes or experimental systems.

* Familiarity with AI/ML technologies and integrating models into software systems.

* Experience architecting modular software systems and designing APIs or service-based architectures.

* Hands-on experience with containerization (e.g., Docker) or reproducible research environments.

* Ability to work in ambiguous, exploratory environments and translate evolving research ideas into working software.

* Strong communication skills and ability to collaborate with researchers, engineers, and external partners.

* Willingness to travel to support integration, demonstration, or customer activities.

Nice to Have

* Experience supporting DARPA, DoW, or other government-sponsored research programs.

* Familiarity with large language models, agentic AI systems, or multimodal machine learning.

* Experience building research testbeds, evaluation frameworks, or simulation environments.

* Background in distributed systems, high-performance computing, or scalable experimentation infrastructure.

* Experience contributing to technical publications, research demonstrations, or conference submissions.

* Exposure to cloud computing platforms (AWS, Azure, GCP) or hybrid research infrastructure.

* Interest in working at the intersection of advanced AI research, national security applications, and emerging technologies.
