• Experience working collaboratively with researchers and engineers
• Ability to mentor and support junior team members
• Eligible to hold UK DV clearance (SC required to start)

Technical Skills

• High-level languages such as Python
• Low-level languages such as C and/or Rust
• Assembly language or strong understanding of low-level architecture internals
• Experience developing offensive security / red team tooling
• Strong understanding of system internals (e.g. Windows, Linux, Android, iOS)
• Familiarity with automated build systems (Azure DevOps, Jenkins, GitHub Actions)
