Simulation Software Engineer Internship Jobs in Charlottesville, VA

Job Summary
General Atomics Integrated Intelligence Inc. (GA-Intelligence) develops software that turns raw data into actionable intelligence. We work in real-time global situational awareness and battle management, processing petabytes of data from hundreds of sources across air, land, and sea. Our systems, including the THRESHER and DRAGONSPELL platforms, support tens of thousands of users across the DoD and Intelligence Community and enable critical decision-making for national security missions. We process hundreds of thousands of observations per minute at the scale of global sensor networks and battlefield telemetry. Our backend architecture uses technologies like Kafka, AWS, NiFi, and GeoMesa, which we designed and open-sourced, to deliver high-throughput, mission-resilient systems that turn streaming data into real-time intelligence.
Why GA-Intelligence?
We solve complex, mission-critical problems. We have spent decades earning the trust of our users and delivering systems they rely on every day. As a privately held company, we can make long-term decisions in the best interest of our customers and our country rather than quarterly earnings reports. Our users rely on our software, our customers come back because we deliver, and our engineers stay because they get to work on real problems that have real impact.
What You'll Do
We are seeking a Senior Software Engineer to lead a large effort to build out the simulation tools that support testing and training for our C2 application. You'll sit on our Battle C2 and Simulation team, a primarily frontend team building the next generation of global situational awareness and battle orchestration capabilities. This is a hands-on senior engineering role, not a formal people-management position. It is roughly 80% backend/fullstack (Java and Spring Boot) powering simulation data and services, and 20% frontend work in the team's user-facing application. You'll drive the technical direction of the simulation effort, working alongside a small group of developers: one focused full-time on simulation with you, and two others who split their time on the C2 UI. Rather than managing day-to-day tasking, you'll set technical direction, make key architectural decisions, and translate mission requirements into performant, scalable services. You'll work closelywith cross-functional teams, including UI/UX engineers, mission engineers, data scientists, and product owners, to design and deliver software for complex user needs. Whether you're building simulation data pipelines, optimizing backend services, or working in the frontend to make sure data reaches the end user, your work will directly support operational missions.
What We Believe
These values reflect how we work, what we value in each other, and the kind of impact we want to have. Solving Meaningful Challenges: Building mission-driven technology that makes a difference Collaborative Culture: Working as a team to push boundaries and innovate Technical Excellence: Encouraging continuous learning, curiosity, and efficiency Idea Meritocracy: Valuing ideas based on impact, not hierarchy
DUTIES AND RESPONSIBILITES:
Senior engineers at GA-Intelligence drive strategy, architecture, and delivery across complex projects. On the Battle C2 and Simulation team you'll lead the technical direction of the simulation effort, set engineering standards, and help shape long-term technical direction. Alongside building and maintaining backend infrastructure, you'll serve as a mentor and technical decision-maker both within the team and with external stakeholders. Lead development activities (backend/fullstack focus) Design, implement, and deliver enterprise-wide backend services in Java and Spring Boot, primarily powering battle simulation data for battlefield command and control, geospatial data management, exploitation, visualization, and analysis Build and integrate the APIs and services that feed the team's user-facing application Research and develop new software processing concepts for situational awareness and battlefield optimization Guide long-term planning and technical roadmaps for backend services and system architecture so they align with organizational goals, operational requirements, and product strategy Contribute to the frontend Work directly in the team's frontend codebase to close fullstack gaps, prototype features, and make sure backend data reaches the UI cleanlyCollaborate externally Serve as a senior technical point of contact for customers, partners, and other engineering teams Communicate effectively with customers, management, and other engineering teams in secure environments Coordinate software deployments and upgrades across distributed environments, including DoD and IC networks Maintain existing capabilities deployed to customer facilities and AWS cloud environments Evaluate and implement cross-platform deployment strategies, ensuring compliance with integration and security standards Engineer performant, high-quality solutions Contribute to system-wide performance tuning and reliability improvements, identifying architectural risks and proposing fixes Develop test scripts and frameworks to verify functionality and produce high-quality software deliverables Lead the simulation effort Drive the technical direction of a large effort to build out simulation tools supporting testing and training for the C2 application Set architectural direction and make key technical decisions across the simulation effort Grow the team's capability Mentor developers contributing to the simulation effort: one full-time alongside you and others splitting time with the C2 UI Contribute to onboarding, skill development, and growth paths for less experienced engineers Provide technical leadership across the full development lifecycle, including design reviews, documentation, ticketing, version control, Agile methodologies, coding standards, and testing practices Operate responsibly Maintain the strict confidentiality of sensitive information Observe all laws, regulations, and other applicable obligations wherever and whenever business is conducted on behalf of the Company Work in a safe manner in accordance with established operating procedures and practices
