Edge Computing Enablement Develop and optimize onboard data processing pipelines for AI/ML inference, image analysis, and telemetry compression. Ensure efficient resource management (CPU, memory, I/O) for real-time edge workloads. Testing & Validation Lead rigorous testing campaigns including unit, integration, and hardware-in-the-loop (HIL) testing. Simulate orbital conditions (thermal, radiation, latency) to validate software robustness. Collaboration & Documentation Work closely with mission systems, payload, and ground segment teams to align software capabilities with mission objectives. Maintain detailed documentation for software architecture, interfaces, and operational procedures. Compliance & Standards Ensure software adheres to space industry standards (e.g., ECSS, NASA, CubeSat protocols) and cybersecurity best practices. Participate in internal audits and reviews to ensure flight-readiness and mission assurance. Continuous Technical Growth Stay abreast of emerging trends in embedded Linux, edge computing, and space-grade software systems. Experiment with new tools, frameworks, and kernel features that could enhance system performance or resilience in space environments. Pursue certifications, courses, or research relevant to aerospace software engineering and embedded systems. Innovation in Edge Computing Explore novel approaches to onboard data processing, including AI/ML inference, distributed computing, and low-latency decision-making. Prototype and evaluate new software architectures that improve autonomy, fault tolerance, or energy efficiency in orbit.
