Oracle Database Operations Lead H/F

Sigma Suisse is partnering with a large international organisation operating in a highly regulated environment to recruit a Oracle Database Operations Lead.

The Role

You will join a global DBA team supporting a very large Oracle estate across on-premises and hybrid/public cloud environments. Based in Geneva, you will take ownership of the database platform system side: operating systems, engineered infrastructure, high availability, replication, monitoring, and the gradual migration from on-prem to cloud.

This is a hands-on, deeply technical role, closely connected to CTRM and analytics platforms, where most critical business data flows transit.

Key Responsibilities

• Own the deployment, operations and support of Oracle database platforms on-prem and in cloud/hybrid environments.

• Administer and secure Oracle 19c+ environments (incl. RAC, Data Guard, RMAN, ASM, CDB/PDB), and ensure high availability and recoverability.

• Operate and improve database monitoring and performance tooling (OEM/monitoring, performance tuning, capacity planning).

• Support Oracle middleware / data replication stack, including Oracle GoldenGate, and contribute to zero-downtime maintenance approaches.

• Provide operational support around CTRM and analytics applications: installation support, critical process monitoring, and close collaboration with business and development teams.

• Work across infrastructure, security, network and application teams regionally and globally.

• Define/document standards, procedures, and contribute to continuous improvement (automation, operational excellence).

• Participate in planned off-hours activities when required (major changes, incidents, occasional weekend work).

Required Experience & Skills

• 1015 years (target) in a similar role as an Oracle DBA / database platform administrator in mission-critical environments.

• Strong hands-on expertise with Oracle 19c+ and core components: RAC, Data Guard, RMAN, ASM, CDB/PDB, performance diagnostics and tuning.

• Solid OS/platform experience: Oracle Linux and Oracle Solaris (standalone and clustered).

• Proven experience with Oracle GoldenGate (replication, resilience, maintenance windows, downtime reduction).

• Experience supporting hybrid/public cloud database services and platforms (AWS and/or OCI, hybrid connectivity and operations).

• Good understanding of database infrastructure: server platforms and enterprise storage (, engineered systems / enterprise compute & storage ecosystems).

• Automation mindset with practical scripting skills (Shell and/or Python) to streamline operations.

• Strong troubleshooting and RCA capabilities across hardware/software incidents.

• Excellent English communication (written and spoken).

• Oracle certification required (as per hiring brief).
