Manage kernel configuration, system services, and integration of middleware components. Board Bring-Up & Hardware Integration: Perform initial board bring-up of avionics computers. Debug hardware/software integration issues across CPU, memory, and peripheral subsystems. Driver Development & Debugging: Develop, port, and maintain Linux device drivers for sensors, communication buses, and memory devices. Debug kernel-space and user-space interactions using hardware debuggers and tracing tools. Platform Engineering & System Hardening: Implement secure boot and code signing for flight-critical binaries. Configure and manage router certificates and other cryptographic assets. Apply Linux security frameworks such as AppArmor and SELinux for mandatory access control. Design and maintain OTA update infrastructure with rollback/A-B partitioning support. Manage system configuration, startup scripts, and fault-tolerant resource allocation.
