Compensation Competitive base + skin in the game equity
Location London, United Kingdom On Site
Stage Early-stage startup backed by tier 1 investors. Small, growing team with exceptionally high ownership.
- + Help design and build our agentic systems that autonomously perform vulnerability research against real targets: firmware, network stacks, mobile OSes, and IoT.
- + Wire emulation (QEMU, Unicorn, Qiling), instrumentation (Frida, DynamoRIO), fuzzing, and exploit primitives into tool interfaces for agents.
- + Build the evaluation and benchmarking infrastructure that tells us whether any of it is actually working.
- + 2–3+ years across systems programming (C/C++, Rust) and ML infrastructure.
- + Comfort with binary analysis, memory corruption classes, and modern mitigations (ASLR, CFI, PAC, MTE).
- + Hands‑on work with agent harnesses — orchestration, tool‑use, eval loops — in production or at benchmark scale.
- + Fluency with at least one emulation stack (QEMU, Unicorn, Qiling, PANDA, FirmAE).
- + Strong RE / debugger chops (GDB, IDA or Ghidra) and the patience to use them.
Nice to Have
- + Pwn-heavy CTF experience (DEF CON finals, PPP, DiceGang, Shellphish, Theori, Team Atlanta).
- + Public CVEs, conference talks, or AIxCC / CGC participation.
- + Kernel or baseband RE.
- + That requirements list is what the fully‑formed version of this role looks like. It's not a filter. If you're sharp, hungry, and funny, apply anyway, even if half the bullets read like a foreign language today.
- + Tech can be learned. Spirit cannot. We've watched the right people pick up binary analysis from scratch and outship ten‑year veterans inside a year.
- + Tell us what you've taught yourself recently and what you'd tear into first here.
