Software Engineer

Zachary Piper Solutions is seeking a Transportation Software Engineer to support a groundbreaking research and development program advancing automated, connected, and intelligent transportation technologies. The Transportation Software Engineer will contribute to next-generation traffic modeling, simulation, and autonomous systems research in McLean, VA through 100% full onsite presence .

Responsibilities of the Software Engineer include:

• Perform traffic analysis across roadway links, intersections, and networks to assess safety and efficiency
• Design ITS and traffic-management solutions including smart signals, sensors, and automated control systems
• Build and run traffic modeling and simulation scenarios, including hardware-in-the-loop and software-in-the-loop environments
• Develop Python scripts and API integrations to automate simulations, data flows, and system interactions
• Test and validate traffic models, simulations, and ITS hardware/software through unit and integration testing
• Improve or extend existing software tools and prototype new research-driven concepts
• Contribute to system architecture and documentation, collaborating within an Agile team using JIRA and Confluence

Qualifications of the Software Engineer include:

• Strong proficiency with Python in Linux; C++ experience preferred
• Experience developing unit and integration tests to support CI pipelines
• Ability to build data interface adapters (e.g., JSON ↔ XML) and integrate with APIs
• Proficiency with Git and collaborative software workflows
• Basic understanding of robotics and autonomous systems concepts
• Must meet Public Trust requirements: U.S. Citizen or Green Card, plus 3 years of recent U.S. residency
• Preferred : experience with C++ on Linux, autonomous systems algorithms, research prototyping, software architecture, and Agile tools (JIRA/Confluence)
