- Analyze complex software and system requirements and develop appropriate technical solutions.
- Work closely with cross-functional members of the engineering organization.
- Develop and evaluate interfaces between hardware and software, including RF control, status reporting, and synchronization between simulation time and hardware.
- Evaluate operational performance requirements and their impact on overall system design.
- Contribute to the design and technical direction of integrated hardware and software systems, including service startup and shutdown, health monitoring, and software configuration and licensing controls.
- Develop software test procedures, software programs, and related technical documentation, with test results and corrective actions traced to requirements.
- Support software integration, verification, and system-level testing activities.
- Identify, analyze, and resolve highly complex software and system-level technical issues.
- Contribute to determining, estimating, and validating the cost and scope of software efforts.
- Ensure software engineering activities support established program cost, schedule, and technical constraints.
- Apply advanced business knowledge when evaluating technical approaches and engineering decisions.
- Guide business or functional teams through technical challenges and engineering decisions.
- Serve as a technical authority and senior technical resource for complex software engineering efforts, providing technical guidance and direction across multidisciplinary teams.
- Coordinate complex technical activities across software, hardware, systems, test, and other engineering disciplines.
- Guide operator-application architecture and integration of browser-based scenario configuration, 3D visualization, live data streams, and system status.
- Guide radar and communication model integration and external API design, including message formats, network and socket interfaces, interoperability, and model performance.
- Evaluate build, test, software-analysis, and server-configuration approaches, and guide resolution of significant software-security and maintainability issues.
