Senior Oracle Database Administrator

Job Description

FISA-OPA is seeking a highly motivated and experienced Senior Oracle Database Administrator to support the Database Management Team within the Financial Systems division. The selected candidate will be responsible for hands-on database administration, operational support, performance tuning, scripting, backup and recovery, monitoring, and troubleshooting for critical financial applications used by the City of New York.
The database environment supports production and non-production systems, including FMS3 Accounting, Vendex, PIP, Debt Management System, IFA, and related applications running on Oracle AIX/Linux platforms and Microsoft SQL Server.
