Software developer

About Us

:

STR’s Intelligence Division researches and develops advanced analytics and software solutions to solve challenging problems relevant to national security. Our team specializes in applying cutting-edge machine learning and computer vision in areas such as biosecurity, mixed reality and autonomous agents to solve national security and intelligence problems. We tackle complex technical challenges under stringent operational constraints by leveraging diverse skill sets from fields such as engineering, computer science, and applied machine learning.

Our projects focus on a wide range of data modalities—including egocentric data, video and imagery, geospatial, and radio-frequency data—powered by the latest advances in deep learning and statistical techniques. Our solutions have real-world impact, allowing U.S. Government analysts and operators to extract and enrich intelligence information across the globe. If you’re motivated by making a difference while working in a collaborative and fast-paced environment and have experience with systems integration, robust application development, and messaging pipelines, we’d like to hear from you.

The Role :

As a Software Engineer, you will use your software development expertise to build custom prototype applications to demonstrate cognitive mixed reality vulnerabilities. You will work with scientists and researchers to implement user test platforms and custom scenarios in the unity development framework for deployment onto a diverse set of mixed reality devices. As part of this role, you will:

• Work with stakeholders to define features for prototype scenarios
• Build, maintain, and test stable user-facing applications for user studies and demonstrations on mixed reality devices
• Implement experimentation platform features such as advanced logging of pose, video imagery, and eye tracker data, sometimes pulling from less readily accessible data streams (on device, embedded, or otherwise)
• Test and support long-term stability for unity build deployment to multiple end stream hardware devices and multiple user types
• Participate in cross-program collaboration, adapting to diverse projects and tools

Our work involves projects of national significance, and the ability to work on-site in our Arlington, VA location will be required

What You Will Do:

• Collaborate closely with team scientists on modeled vulnerabilities and storyboard those into real user demonstrations, often involving development of custom user interfaces, state machines, and multiple unity scenes
• Develop robust experimentation logging tools that can store pose estimates, actions, and eye tracker records as a function of interactions or specific event triggers
• Communicate with technical and non-technical stakeholders to ensure requirements are well-understood and actionable
• Create binary builds and deployment instructions and support scientist requests related to usability and experimentation features

Who You Are:

• Ability to obtain and maintain a Top Secret clearance, for which U.S citizenship is needed by the U.S government
• BS or MS in Computer Science, Engineering, or a related field, or relevant industry experience
• 3+ years of experience in software development
• Proficiency in navigating, designing, and contributing to large, complex code bases
• Strong proficiency in a programming language, preferably C# or game engine adjacent languages
• Strong debugging and testing skills for maintaining resilience and reliability in hardware deployed environments
• Working knowledge of version control systems (e.g., Git) and CI/CD pipelines

Even Better:

• Experience working specifically on mixed reality systems such as meta quest or hololens platforms
• Development experience with mixed reality-compatible game engines besides unity
• Experience with deployed neural network solutions (onnx models, pytorch, etc.)
• Front end user interface and user experience design

Why Join Us?

At STR, we are passionate about applying state-of-the-art machine learning techniques, biometrics, and computer vision to solve critical problems for the U.S. Government. You’ll work alongside a team of talented engineers and researchers on a wide range of projects, from developing production-grade software to rapidly prototyping novel concepts and features. If you’re motivated by solving complex technical challenges—with the chance to contribute to national security efforts—we think you’ll thrive in our innovative, mission-driven environment.
