Embedded Systems Staff Engineer

Team: IT

Location: US

Commitment: Full-time

Workplace Type: remote

Accountabilities

You will take technical ownership of ARM and AArch64 execution capabilities, ensuring their correctness, compatibility, performance, and continued development. Your responsibilities will include:

Lead the architecture, maintenance, and evolution of ARM and AArch64 execution support through emulation.

Diagnose complex correctness, compatibility, and performance issues involving instruction semantics, memory management, exceptions, system calls, signals, threading, and process initialization.

Implement support for new ARM architectural features, instruction-set extensions, ABI variants, and execution environments.

Investigate and resolve behavioral differences between native execution, QEMU emulation, and internal analysis engines.

Improve the performance, determinism, observability, and reliability of large-scale emulated workloads.

Design and maintain comprehensive test suites and regression infrastructure covering instruction-level and end-to-end ARM behavior.

Debug customer binaries and firmware involving unusual platform, compiler, or operating-system behaviors.

Collaborate across technical disciplines to advance binary analysis and execution capabilities.

Requirements:

The ideal candidate combines extensive low-level systems engineering experience with deep knowledge of ARM architectures, Linux internals, and native-code debugging. You should demonstrate strong technical ownership and the ability to solve complex engineering challenges.

6+ years of experience developing software in C/C++ on Linux.

Significant experience with low-level systems software, including emulators, virtual machines, operating systems, compilers, debuggers, binary translators, hypervisors, or dynamic instrumentation systems.

Deep understanding of ARM and/or AArch64 assembly, calling conventions, exception models, privilege levels, and memory semantics.

Strong knowledge of Linux process execution, including ELF loading, virtual memory, signals, threads, system calls, dynamic linking, and debugging facilities.

Proven experience debugging complex native-code failures using tools such as GDB, LLDB, strace, perf, sanitizers, core dumps, or custom instrumentation.

Ability to reason about instruction-level behavior and identify subtle differences between architectures and execution engines.

Familiarity with fuzzing, symbolic execution, dynamic binary analysis, or program instrumentation.

Strong software design skills and experience taking ownership of technically complex systems.

Preferred qualifications:

Experience with OCaml or another functional programming language.

Background in vulnerability research, reverse engineering, or firmware analysis.

Bachelor's degree in Computer Science or a related technical field, or equivalent practical experience.

Must qualify as a U.S. Person for ITAR purposes, such as a U.S. citizen, lawful permanent resident, or protected individual.

Benefits:

Hourly compensation ranging from $96.75 to $133.03, based on U.S. national estimates.

Potential eligibility for a discretionary bonus program or commission plan, subject to applicable program rules and individual and organizational performance.

100% remote, work-from-home arrangement within the United States.

Inclusive and collaborative working environment that values diverse backgrounds, perspectives, and experiences.

Opportunity to work on advanced security technologies and technically challenging engineering problems.

Commitment to accessibility and reasonable workplace accommodations.
