- Monitor internal environments for anomalies and respond to incidents in coordination with incident response playbooks.

- Demonstrated ability to collaborate cross-functionally with IT, compliance, and business units
- Excellent communication skills with the ability to translate complex security topics to non-technical stakeholders
- A figure-it-out, resourceful attitude and act with a sense of urgency
Nice to have:
