• Event-Driven Systems: Manage and troubleshoot data flowing through cloud-native event-driven messaging systems, specifically AWS SQS and SNS.

• CI/CD & Version Control: Treat SIEM configurations as code. Manage configurations using GitHub and automate testing and deployment via Jenkins or similar CI/CD pipelines.

• SIEM Analysis & Troubleshooting: Analyze and query log data within Splunk to audit data quality, troubleshoot parsing errors, and investigate system messages.

• Database Querying: Write and understand SQL syntax to interact with relational databases for data validation, lookups, and reporting.

Soft Skills & Experience:

• 3+ years of experience in Security Engineering, Data Engineering, or a DevSecOps role.

• Strong analytical and troubleshooting skills with a keen eye for data anomalies.

• Ability to work collaboratively in an agile environment.

Nice to Have:
