Preferred qualifications

• Strong automation and scripting skills using Python, Bash, Ansible, PowerShell or similar technologies; C# and .NET experience is an additional advantage.
• Experience owning reliability strategy or platform initiatives spanning multiple teams or business units.
• Experience modernizing legacy financial systems into cloud-native or hybrid architectures with a focus on resilience and compliance.
• The impact you’ll make
