Based on similar roles (title + domain + location).

Responsibilities

  • ● Design, implement, and optimize core kernel infrastructure, including virtual
  • ● memory page tables, thread schedulers, timers, and object architectures.
  • ● Develop and maintain sound multi-language FFI boundaries to safely bridge
  • ● legacy C++ subsystems with modern Rust components while managing strict stack
  • ● and memory constraints.
  • ● Implement advanced low-level diagnostic frameworks and execute comprehensive
  • ● test categories-including early boot, core, and stress testing-to isolate
  • ● non-deterministic system behaviors.
  • ● Collaborate across compiler, tools, and security infrastructure teams to
  • ● audit code generation, refine code coverage, and systematically document
  • ● memory invariants and lock hierarchies.

Requirements

  • ● Master's degree or PhD in Engineering, Computer Science, or a related
  • ● technical field.
  • ● components, such as virtual memory layouts, low-level context switching,
  • ● thread scheduling, or primitive IPC mechanisms.
  • ● Demonstrated expertise in low-level debugging, diagnostics, and root cause
  • ● analysis across execution phases like early boot, hardware interrupts, or
  • ● power management routines.
  • ● Deep understanding of Rust programming; soundness, unsafe code encapsulation,
  • ● multi-threaded mutability, and mitigating bare-metal runtime or stack
  • ● constraints.
  • ● Strong technical documentation and collaboration practices, including
  • ● authoring design documents, detailing invariants, and auditing code with
  • ● security teams.
  • ● ABOUT THE JOB:
  • ● The Zircon Kernel team builds the foundational operating system core that drives
  • ● Fuchsia, establishing essential security, performance, and reliability
  • ● boundaries at the bare-metal layer. As the lowest layer of Fuchsia, Zircon
  • ● handles core object architectures, physical and virtual memory management
  • ● through page tables, and primitive inter-process communication mechanisms. The
  • ● team is currently executing a major architectural migration to incrementally
