Hybrid working model

The Incident Response team within our organization's Cyber Defense Center is a group of dedicated incident responders working to limit the impact of security incidents across our global infrastructure. We coordinate the response to cybersecurity incidents, run investigations across the organization, and contribute to strategic security initiatives.

- Lead incident reviews, spot areas for improvement, and help implement them, including updates to guidelines, runbooks, and internal processes.
- Contribute ideas and build automation scripts or custom tooling to enhance the team's internal toolset.
- Analyze complex attack patterns and threat actors, draw out technical insights, and recommend ways to improve detection and defense capabilities.
- Work closely with internal teams such as Threat Intelligence, Vulnerability Management, and Business Applications, as well as external partners, to keep incident response coordinated end to end.
- Take part in on-call rotations supporting the team's round-the-clock availability for critical incidents.

What you'll bring
