Firmware Emulation Engineer (Linux)

§The role

Zealot's emulation stack lets autonomous agents boot, instrument, and interrogate opaque firmware — the foundation of every exploit pipeline we ship. You'll own the Linux surface of that stack.

§What you'll do

• +Extend our QEMU/Styx fork with new peripheral models, syscall handlers, and introspection hooks.
• +Drive coverage on real-world targets shipped by vendors we don't have SDKs for.
• +Partner with the AI team to expose emulator state to agents in a way they can actually reason about.
• +Own reliability: when an agent's run diverges from silicon, you find out why.

§Who we're looking for

• +Deep fluency in Linux internals, kernel subsystems, and userland bring-up.
• +Reverse engineering chops — IDA, Ghidra, Binary Ninja, whatever you like.
• +Comfort in C, Rust, and Python; you've hacked on emulators or virtualization stacks before.
• +Clearance-eligible, U.S. person.
