  • Dev Ops & Cloud Deployment: Orchestrate containerized deployments and manage backend infrastructure on cloud platforms, utilizing automated CI/CD pipelines to ensure rapid, reliable, and secure software delivery.
  • Compliance & Regulatory Adherence: Ensure all software development and system configurations strictly adhere to financial regulations, industry standards (e.g., EMV, ADA), PCI DSS, and internal corporate compliance policies.
  • System Diagnostics & Troubleshooting: Diagnose, debug, and resolve complex software and network issues within a highly critical, distributed, and high-availability production environment.
  • Cross-Functional Collaboration: Partner closely with hardware engineers, cybersecurity specialists, compliance officers, and business stakeholders to align technical solutions with operational and business objectives.
