• Strong understanding of Linux internals, including scheduling, memory management, interrupt handling, filesystems, and system initialization.
• Proficiency in C, ARM Assembly, and Linux build systems.
• Experience with Linux kernel development, debugging, and customization.
• Understanding of SoC boot flows, bootloaders, firmware, and Linux bring-up.
• Experience with Linux Device Tree development and board/platform configuration.
• Hands-on experience with hardware debugging tools such as JTAG debuggers (i.e. Lauterbach Trace32 [T32]), or equivalent.
• Experience developing telemetry, monitoring, and instrumentation tools for system debugging, performance analysis, and validation.
• Experience with Python, Bash, or similar scripting languages for automation and tooling.
• Familiarity with Git, CI/CD workflows, and modern software development practices.
• Experience with filesystem management, image creation/modification, flashing, and software deployment processes.

Role and Responsibilities

• Enable and maintain a custom Linux software stack used for platform enablement, validation, and characterization.
• Develop, maintain, and optimize kernel drivers and low-level platform software.
• Debug complex issues spanning hardware, firmware, bootloaders, Linux kernel, and userspace components.
• Develop and maintain Device Tree configurations and platform-specific software components.
• Design and implement telemetry, monitoring, and automation tools to improve system observability and diagnostics.
• Build tooling that interacts with hardware debuggers and platform interfaces to collect, analyze, and automate system data collection.
• Collaborate with silicon, firmware, performance, and validation teams to identify, root-cause, and resolve platform issues.
• Develop tools and workflows that improve platform stability, usability, and engineering productivity.

Level of Responsibility

• Autonomy: Work independently with minimal supervision while driving platform enablement and debugging efforts.
• Communication: Communicate complex technical concepts effectively across multidisciplinary teams.
• Influence: Contribute to platform architecture, software design, and debugging methodologies.
• Task Management: Manage multiple bring-up, development, and support activities across hardware programs.
• Innovation: Develop new tools, telemetry solutions, and automation frameworks to improve engineering efficiency.
• Problem Solving: Diagnose and resolve complex hardware/software integration issues across the full platform stack.

Preferred Qualifications

• Master's degree or PhD in Computer Engineering, Computer Science, Electrical Engineering, or related field.
• 5+ years of experience in Linux kernel development, embedded Linux, BSP development, platform enablement, or systems software.
• Experience with hardware bring-up, post-silicon validation, or low-level platform debugging.
• Experience using Lauterbach Trace32 (T32) or similar hardware debug environments.
• Experience developing telemetry, observability, or performance monitoring solutions for embedded or high-performance systems.
