Design and operate cloud-native architectures in AWS, including serverless and event-driven systems
Work within and integrate with Q2’s enterprise banking platform, including navigating and modifying C#/.NET integration points when needed
Improve observability, testing, deployment practices, and operational reliability across production services
Partner with data scientists, product teams, and other engineers to bring fraud detection capabilities from concept into production
Research new technologies and engineering approaches and apply them where they meaningfully improve the platform
