About the role

Key responsibilities & impact

Own and evolve Bugcrowd’s ARM and AArch64 execution support using emulation
Diagnose correctness, compatibility, and performance issues involving instruction semantics, memory management, exceptions, system calls, signals, threading, and process startup
Add support for new ARM architectural features, instruction-set extensions, ABI variants, and execution environments
Investigate discrepancies between native execution, QEMU execution, and Bugcrowd’s analysis engines
Improve the performance, determinism, observability, and reliability of large-scale emulated workloads
Develop test suites and regression infrastructure for instruction-level and end-to-end ARM behavior
Debug customer binaries and firmware exercising unusual platform, compiler, or operating-system behavior
Work at the boundary of CPU emulation, operating-system semantics, binary analysis, fuzzing, and symbolic execution

Requirements

What you’ll need
