The Role
We are seeking a DevOps Engineer to join a dynamic, high-performing engineering team.

• Build and integrate logging and monitoring solutions across Splunk, Dynatrace, and Azure Log Analytics
• Lead Managed File Transfer (MFT) modernization and improve data flows across enterprise systems
• Contribute to operational ownership including L2/L3 incident triage, system hardening, and reliability improvements
• Support cloud initiatives and platform improvements across Azure and AWS environments
• Collaborate with cross-functional teams to establish shared engineering standards, patterns and best practices
• Take ownership of assigned projects and deliver solutions independently
