You’ll be part of a globally distributed team built on trust, ownership, and self-management.

It’s a fully remote role, we are hiring across European timezones.

What you’ll be responsible for

• Own and drive the Application Security workstream as the security DRI across all Domains and Pods.
• Build automated security controls across the delivery loop, including secret scanning, SAST, SCA, IaC, container, dependency, and DAST gates.
• Embed security into product discovery, threat modeling, acceptance criteria, and architecture decisions.
• Define controls for AI-generated code, including dependency risk, tenant isolation, prompt injection, agent misuse, and risky migrations.
• Own the security reviewer AI agent and improve its detection quality, escalation logic, and coverage.
