Information Security Analyst - Detection & Response (f|m|x)

As an Information Security Analyst, you will be part of idealo’s highly motivated Security Detection and Response (SDR) Team. In this role, you will help shape the future of security in a fast-growing, increasingly AI-driven cloud environment. It is a fantastic opportunity to bring your ideas to life, strengthen idealo’s security posture, and make a tangible impact across the organization.

Together with your team, you will take ownership of security monitoring, anomaly detection, bot and brand protection, and incident response — continuously refining SIEM rules and playbooks to enhance actionable insights and strengthen our response capabilities.

You will actively contribute to embed “security by design” into our AI and cloud services, ensuring resilience and trust at scale.

About your new role

• Investigate potential security incidents, perform digital forensics, and gather evidence.

• Create AI agent workflows supporting alert verification and incident response.

• Lead and support incident response activities.

• Define and revise Indicators of Compromise (IoCs) to detect attacks, intrusions, or illegal behaviors. Create corresponding detection rules and fine-tune them.

• Perform analysis of bot traffic harming idealo’s platform and create effective rules for handling it.

• Communicate findings clearly to both technical and non-technical stakeholders, helping teams implement effective countermeasures.

• Collaborate closely with infrastructure, development and security teams to embed security into daily operations and protect idealo’s data and infrastructure from attacks.

• Familiarity with SIEM platforms, anomaly detection, and infrastructure- and application log analysis.
