• Debug complex issues on embedded targets and analyze low-level behavior using embedded debugging techniques and tools. The examples include experience with debugging software on embedded systems and highlight strong debugging skills.• Collaborate with local and international engineering teams, align technical concepts, propose solutions, estimate effort, and track progress.

• Knowledge of real time hypervisor would be considered a plus.
