- Architect and implement SDN-based control-plane frameworks for topology management, policy enforcement, and cross-link orchestration.
- Integrate encryption, authentication, secure routing, and other cybersecurity protections into the communications stack.
- Implement real-time communication software for radiation-tolerant processors and constrained onboard computing environments.
- Develop networking simulation and emulation frameworks and contribute to system architecture, protocol selection, interface definitions, and end-to-end communication strategy.
- Ensure reliability through redundancy, error handling, watchdog systems, autonomous recovery, and secure failover mechanisms.
- Collaborate with RF, DSP, FPGA, security, hardware, and software teams and participate in code reviews, design reviews, testing, and mission-readiness activities.
