Software Engineer - Full-Stack / Simulation

• Develop Web-Based Visualizations: Build intuitive, high-performance dashboards and interactive web tools to visualize complex datasets, including atmospheric and environmental sensor data.
• Architect Secure Data Pipelines: Design and implement end-to-end secure messaging solutions to move data reliably between local tactical devices (including micro-controllers and mobile) and cloud-based infrastructure.
• Build Full-Stack Applications: Develop and maintain the backend APIs and frontend interfaces that serve as the control centers for our simulation ecosystems.
• Develop Simulation Environments: Contribute to the creation of interactive, collaborative 3D environments using game engines (Unity3D preferred).
• Ensure Security & Quality: Implement robust encryption (e.g., AES-256), secure network protocols (TLS), and access controls; write automated tests and participate in code reviews to ensure our software is resilient and reliable.
• Collaborate on R&D: Work closely with hardware teams and subject matter experts to prototype new capabilities for defense and rapid-innovation contracts.

• Experience: 4+ years of professional software development experience.
• Core Full-Stack Skills: Strong programming skills in modern languages (such as Python, JavaScript/TypeScript, or C#) and experience building web applications backed by databases.
• Networking & Security: A solid understanding of secure, real-time data communication, including encryption standards (AES, TLS), and secure networking principles across the entire lifecycle, from edge devices to the cloud.
• Visualization & Data: Experience with web-based data visualization libraries and a knack for making complex technical datasets intuitive. Preferred experience includes working with scientific data formats (e.g., NetCDF, HDF5), weather/environmental modeling outputs (e.g., WRF), and consuming GIS or meteorological APIs for real-time spatial mapping.
• Game Engine Exposure: Professional or strong project experience working with 3D applications, digital twins, or game engines (Unity3D preferred).
• Testing & Quality: Experience writing clean, reliable code and using automated testing frameworks to ensure software quality.
• AI/ML Integration: A proactive interest in AI/ML, with the ability to support the full lifecycle of intelligent solutions-from identifying and sourcing high-quality training data and refining models, to integrating these tools into simulation pipelines to create clear, actionable value for our projects.
• Adaptability & R&D Mindset: A drive to learn new frameworks, tackle unique R&D challenges, and work in an agile, collaborative environment where your ability to solve novel problems is more important than your familiarity with any single legacy tool.

Desired Skills and Experience

• Data Serialization: Experience with Google Protocol Buffers (Protobuf) for efficient, high-speed data exchange.
• Tactical Edge Development: Experience with mobile app development using Android Studio or the Android Team Awareness Kit (ATAK) plugin ecosystem.
• Platform Experience: Experience working across the stack, from firmware/micro-controllers to consumer mobile and cloud environments (AWS GovCloud).
• Defense Networking: Familiarity with defense data protocols (e.g., Cursor-on-Target, DIS, HLA) or geospatial mapping tools.

Physical Requirements and Work Environment

• Normal office and lab environment.
• Occasional work in simulation labs, field testing environments, or training facilities.
• Travel Requirements: Up to 35%
