Database Administrator- Grade 14

The Database Administrator is a member of the Archive/Pipeline Operations Group within the ALMA Department of Computing (ADC). The role is responsible for the administration, availability, performance, security, resilience, and lifecycle management of ALMA's production database platforms, with primary emphasis on the high-availability Oracle environment.

The position installs, configures, patches, tests, tunes, monitors, backs up, recovers, and supports Oracle infrastructure, including Grid Infrastructure, ASM, RAC, GoldenGate, and Oracle Enterprise Manager. The role also supports other relational database technologies used by the Observatory and works closely with system administrators, software engineers, data management teams, ALMA Regional Centers, and technical counterparts in Europe, North America, and East Asia.

KEY RESPONSIBILITIES

• Administer and maintain Oracle database environments across development, test, integration, and production platforms.

• Manage the full lifecycle for both Single-Instance and RAC databases — including installation, configuration, patching, migration, upgrade, and support for Oracle Grid Infrastructure, ASM, GoldenGate, and Cloud Control.

• Monitor database availability, capacity, performance, replication, and overall health; identify risks and implement corrective actions.

• Perform database performance analysis and tuning, including SQL and PL/SQL optimization, profiling, indexing, and execution-plan review.

• Administer database security, including users, roles, privileges, authentication, auditing, and compliance with ALMA cybersecurity policies.

• Plan and execute database capacity, lifecycle, and growth activities in coordination with infrastructure and service owners.

• Design, implement, test, and maintain backup, recovery, disaster-recovery, and failover capabilities in coordination with the IT Group.

• Administer and troubleshoot Oracle GoldenGate replication between geographically distributed ALMA sites.

• Review, test, validate, and authorize production schema changes, database releases, and Oracle-related software upgrades.

• Develop and maintain technical documentation, operational procedures, standards, architecture records, and recovery runbooks.

• Evaluate new Oracle capabilities and related technologies, and recommend improvements that increase reliability, security, automation, or operational efficiency.

• Provide Linux and storage administration support related to database platforms and collaborate with system administrators on operating-system, network, and storage issues.

• Coordinate technical support cases with Oracle and other vendors, ensuring timely diagnosis, escalation, resolution, and knowledge capture.

• Participate in incident response, root-cause analysis, problem management, maintenance activities, and service-continuity planning.

• Contribute to automation, monitoring, and observability initiatives using scripting, metrics, dashboards, logging, and alerting tools.

• Provide technical guidance, share knowledge, and support cross-training within the Archive/Pipeline Operations Group.

WORKING CONDITIONS

• Work is typically performed in an administrative environment, mainly indoors in Santiago Central Office (SCO) with periodic visits to the Operations Support Facility facilities (OSF) (2900m elevation) and occasional trips to the Array Operations Site (5000m elevation). Physical health compatible with high altitude conditions. A successful High Altitude Medical Exam is a necessary condition of employment.

• Participation in scheduled maintenance, on-call support, and emergency activities outside normal working hours may be required.

• Occasional national and international travel may be required for meetings, training, coordination, or technical activities.

• Work is primarily performed indoors in an office and data-center environment.
