Job Description

We’re hiring a Senior Security Engineer to join a growing SaaS scale-up, with a strong focus on hands-on security engineering, automation and cloud security.


You’ll use AI to build agents and automate security workflows, write scripts and tooling, secure a predominantly AWS (70%) / GCP (30%) cloud environment, and support vulnerability management and remediation. This is a build-focused role where you’ll have the freedom to experiment with AI, improve existing processes, implement security tooling and engineer scalable security solutions. This is the first security engineering hire so the role will initially be very broad and flexible, allowing you to specialise as the team grows.


We’re looking for someone with hands on security engineering experience, strong cloud security knowledge, scripting/automation skills, and genuine hands-on experience using AI/LLMs to build or automate things.


This role requires hybrid working (2 days in office) in central London.

Salary £90-100k + share options


Visa sponsorship is available for candidates already living and working in the UK on a skilled worker visa.
