## Description

We are hiring a Security Engineer to own the security of the systems every OLIX employee depends on: identity, devices, email, collaboration tools and our cloud estate. Our IP is the company, and protecting it is a hands-on engineering job.

You will own detection and response, harden our tooling, run vulnerability management and build the technical controls behind our ISO 27001 certification in 2027. You will work alongside our AI Security Engineer and IT Systems Engineer, and you will use automation and AI to make a small team cover a fast-growing company. This is a high-ownership role with the freedom to define how security engineering works at OLIX., * Own detection and response: triage every security alert, work incidents end to end with our managed detection and response partner, and fix the root cause.

 * Harden the core estate: configure and baseline security across identity, endpoints, Google Workspace, Slack, Atlassian, GitHub and AWS.
 * Run vulnerability management: set remediation service levels, close vulnerabilities in order of real risk, and report progress every week.
 * Build certification controls: operate and evidence the controls for ISO 27001, SOC 2 and NIST CSF.
 * Extend detection coverage: connect new log sources to our SIEM and write the detection rules for them.
 * Automate security work: build the scripts, agents and workflows that remove manual security tasks.
