  • Process-driven, able to follow and adapt SOPs under pressure.
  • Strong communicator, able to break down technical findings for diverse audiences.
  • Detail-oriented, curious, and creative when tackling unexpected challenges.

Your Experience

  • 2–3 years+ as a SOC or SecOps Analyst, with practical incident handling and threat detection experience.
  • Proven ability to optimise detection tools, reduce noise, and drive SOC improvements.
  • Comfortable with shift work and participating in on-call rotas when required.
