Partner with vendors, infrastructure teams, and business stakeholders to remediate audit findings and vulnerabilities in alignment with TD security controls and standards.
Support business and operations teams during UAT for vendor and TD internal production releases.
Coordinate digital certificate renewals across all environments.
Document data flows, process flows, network and infrastructure diagrams.
Analyze issues across Oracle databases to validate transactions and support incident resolution.

Monitoring & Observability

Provide high quality application and user support to help ensure global IT systems remain available, reliable, and performant.
Use Dynatrace and Splunk for monitoring, log analysis, and incident investigation.
Review trends and alerts proactively to identify issues before they affect production.
Partner with engineering teams to strengthen monitoring, logging, and alerting capabilities.

Collaboration & Continuous Improvement

Collaborate with development, infrastructure, database, network, security, and vendor teams to resolve complex issues.
Provide knowledge transfer and guidance to L1 and L2 support teams.
Maintain runbooks, procedures, and support documentation.
Participate in post incident reviews and continuous improvement initiatives.

Required Qualifications To Be Successful In This Role

Must Have skills:

Experience in payment operations, risk management, exception handling, and production support.
Understanding of authentication tokens and certificate based authentication.
Strong knowledge of Spring Boot microservices and REST APIs, with hands on experience supporting production issues, deployments, and service reliability.

Experience using Copilot and AI enabled tools to improve support analysis, documentation, automation, and operational efficiency.
Proficiency in T SQL development and debugging.
Programming experience in Java or comparable languages.
Experience using Dynatrace and Splunk for monitoring and incident analysis.
Strong analytical and troubleshooting skills in high pressure production environments.
Strong written and verbal communication skills.
