§What You'll Do

  • Build the agentic systems that let Zealot automatically understand and emulate embedded targets at scale.
  • Design workflows that can reverse firmware, map boot logic and runtime dependencies, and determine what is required to boot and execute unfamiliar firmware under emulation.
  • Turn firmware reversing and emulation from slow, manual expert work into autonomous, scalable, and repeatable AI-driven capability.
  • Extend Zealot's platform across Linux-based devices and non-Linux / RTOS environments.

§Requirements

  • Strong reverse engineering experience with embedded firmware, binaries, and boot flows.
  • Strong understanding of embedded systems architecture, Linux-based devices, and low-level runtime behavior.
  • Experience analyzing firmware from routers, cameras, network appliances, telecom gear, or similar embedded targets.
  • Strong C/C++ or Rust skills for systems-level work.
  • Ability to work from incomplete documentation and rapidly build understanding from firmware and runtime behavior.

§Nice to Have

  • Experience with QEMU, firmware rehosting, or system emulation.
  • Proficiency with tools such as Ghidra, IDA, Binwalk, GDB, and strace.
  • Experience patching firmware and building shims for hardware dependencies.
  • Familiarity with ARM, MIPS, AArch64, PowerPC, VxWorks, or similar architectures and OSes.
  • Experience with Hikvision, TP-Link, Huawei, or similar embedded ecosystems.
  • Experience building with LLMs and AI agents.
  • Strong technical ability, offensive judgment, and a reputation for operating at the top tier of the field.

§You Are

  • Clearly interested in stepping away from purely manual research and moving toward the development of AI systems.
  • Building something massive matters more to you than comfort, titles, or predictability.
  • You want to be early at a company that will change an industry, and you're ready to do what that actually takes.
For Recruiters

Note to recruiting firms: Reverse engineering is the core requirement. Emulation, QEMU, and rehosting experience are strong pluses, but not mandatory. Strong preference for candidates who can both understand how embedded targets work and translate that work into practical tooling.
