עיקרי התפקיד
Design and implement the virtualization layer and hypervisor support for our custom RISC-V implementation.
Take ownership of the H-spec implementation, ensuring our software stack is strictly compliant with (or intentionally extends) the RISC-V standard.
Develop and maintain hypervisor-level software to support guest execution, world-switching, and resource isolation.
Debug and resolve high-pressure integration issues between our evolving hardware and the software stack (KVM/Hypervisor).
Implement and optimize memory management strategies, including two-stage translation and I/O virtualization.
Collaborate closely with hardware teams to validate the H-extension and provide feedback on hardware design from a software perspective.
Wide system impact through collaboration with software engineers, hardware engineers, and other stakeholders.
דרישות
B.Sc in Electrical Engineering, Computer Science, or equivalent experience.
7+ years of experience as a low-level software engineer.
Deep technical literacy: Ability to digest and implement complex technical specifications, specifically the RISC-V H-extension (Hypervisor).
Virtualization expertise: Solid understanding of virtualization fundamentals, including nested page-tables, virtualized I/O, and IOMMU logic.
Strong OS Internals: Proficiency in kernel-level development and memory management.
Strong, proven coding skills in C and C++.
Hardware-aware debugging: Ability to root-cause complex integration issues across the stack, distinguishing between software bugs, hardware errata, or spec misinterpretations.
A proactive, can-do approach and flexible mindset.
Excellent written and verbal communication skills.
Ability to work both independently and as part of a collaborative team.
