Senior Data System Software engineer: Oracle Database 26ai and client drivers System Test Engineering

Database Product Development | Senior Lead or Principal Level

Role summary This role combines hands-on Oracle database development with component, integration, system, stress, and performance testing. The engineer will build automated test solutions for Oracle Database 26ai, Oracle client drivers, converged database features, and the major Oracle client drivers on Windows and Linux.

Team and mission

The SHARP VLDB organisation improves the scalability, high availability, reliability, and performance of Oracle Database and cloud services. The team designs realistic, high-volume and highly concurrent workloads that expose product defects and architectural limitations before release. Engineers work closely with database kernel, feature, client drivers, cloud, and support teams to reproduce issues, verify fixes, and strengthen product quality across on-premises and cloud deployments.

  • Design and develop production-scale database schemas, data generators, workload drivers, and application logic using SQL, PL/SQL, Python, Java, JavaScript or Node.js, C/C++, and C# as appropriate.
  • Create highly automated end-to-end test suites that simulate large enterprise applications, high concurrency, long-duration operation, mixed workloads, and very large databases.
  • Review Oracle Database 26ai feature designs and translate functional and architectural requirements into test strategies, coverage matrices, test specifications, and reusable automation.
  • Validate Oracle Database 26ai vector and AI capabilities, including vector data types, vector indexes, similarity search, hybrid vector and text scenarios, embedding workflows, concurrency, correctness, performance, and upgrade compatibility.
  • Develop comprehensive coverage for XDB and XML processing, JSON data management and APIs, and Oracle Text indexing, search, synchronization, security, and mixed-workload interoperability.
  • Test ODAC and ODP.NET components across Windows and Linux, including platform-appropriate ODP.NET Core, Managed, and Unmanaged provider scenarios, connection management, pooling, transactions, data type mappings, high availability, security, and framework integration.
  • Build a consistent cross-driver test matrix for python-oracledb, node-oracledb, OCI C, and JDBC to validate feature parity, protocol behavior, data type support, error handling, failover, performance, and backward compatibility.
  • Exercise client and server combinations across Windows and Linux, including installation, configuration, networking, TLS, authentication, character sets, file systems, process and memory behavior, and operating-system-specific regressions.
  • Test Release Updates, one-off patches, client upgrades, rolling maintenance, database upgrades, and mixed-version scenarios while preserving data correctness and service availability.
  • Execute tests on standalone databases, multitenant CDB and PDB environments, RAC and ASM clusters, Data Guard configurations, Exadata, and cloud or Autonomous Database environments as applicable.
  • Develop monitoring and diagnostics for database, operating system, network, application, and client layers; analyze traces, dumps, logs, wait events, execution plans, memory usage, and performance profiles.
  • File high-quality defects with reproducible evidence, isolate failures to the responsible layer, collaborate with development teams on root cause, and verify fixes across platforms and client stacks.
  • Enhance test frameworks based on customer escalations and field defects, and participate in feature reviews, certification exercises, documentation reviews, and quality readiness assessments.
