Experience providing advanced application support, including root cause analysis and resolution of complex production issues.
Bachelor's degree in a relevant field or equivalent professional experience.

Beneficial Skills & Qualifications

Familiarity with Python for scripting, automation, or data processing tasks within an enterprise application context.
Exposure to Oracle financial systems or ledger-based platforms, providing useful context for the business domain.
Experience working within global or follow-the-sun support and delivery models across distributed teams.
