Oracle is seeking an experienced Consulting Member of Technical Staff (CMTS) to join the RAC Developmentorganization. In this role, you will contribute to the architecture, design, implementation, performance optimization, and scalability engineering of Oracle RAC and related high-availability technologies.
As a senior individual contributor, you will work on some of the most challenging problems in distributed systems, including cluster coordination, concurrency control, fault tolerance, workload management, and cloud-scale database infrastructure. A significant focus of the role is ensuring Oracle RAC continues to deliver industry-leading performance and scalability across increasingly demanding workloads and deployment sizes. You will identify and eliminate system bottlenecks, optimize critical code paths, and drive innovations that improve throughput, latency, efficiency, and scale.
Working closely with development, quality assurance, performance engineering, cloud operations, and support teams, you will help shape the future of Oracle's clustered database technology.
Key Responsibilities
- Design, develop, and enhance core Oracle RAC functionality and cluster infrastructure.
- Drive architecture and implementation of distributed systems features focused on scalability, availability, and performance.
- Analyze workload behavior and identify bottlenecks in cluster communication, synchronization, cache fusion, and resource management.
- Design and implement enhancements that improve throughput, latency, scalability, and resource efficiency for large-scale database deployments.
- Develop robust, maintainable, and highly reliable code primarily in C/C++ and related systems programming technologies.
- Investigate and resolve complex software issues across large-scale clustered database environments.
- Lead performance analysis, benchmarking, and scalability testing efforts for RAC components and infrastructure.
- Collaborate with OCI and Exadata engineering teams to optimize RAC performance in cloud and engineered systems environments.
- Perform root-cause analysis of complex customer-reported performance and availability issues and drive long-term solutions.
- Use profiling, tracing, and observability tools to identify opportunities for system-wide performance improvements.
- Lead technical design discussions and contribute to strategic product direction.
- Mentor junior engineers and provide technical leadership across teams.
- Participate in code reviews, design reviews, and architecture reviews.
- Author technical specifications, design documents, and operational guidance.
Required Qualifications
BS, MS, or PhD in Computer Science, Computer Engineering, or related field.
8+ years of software development experience, preferably in systems software, databases, operating systems, or distributed systems.
Strong programming skills in C and/or C++.
Deep understanding of operating system internals, including:
- Process and thread management
- Memory management
- Synchronization primitives
- I/O subsystems
- Linux/UNIX internals
Experience designing, developing, and debugging large-scale distributed systems.
Strong understanding of performance analysis and scalability principles.
Experience diagnosing CPU, memory, I/O, networking, and concurrency bottlenecks in complex systems.
Experience with performance profiling, tracing, and debugging tools.
Strong problem-solving and analytical skills.
Excellent written and verbal communication skills.
Preferred Qualifications
- Experience with Oracle Database, RAC, Clusterware, ASM, Data Guard, or related technologies.
- Knowledge of distributed consensus, cluster membership, distributed locking, cache coherency, or workload balancing mechanisms.
- Experience with performance engineering for database systems, clustered applications, or large-scale cloud services.
- Familiarity with cloud-native infrastructure and Oracle Cloud Infrastructure.
- Experience conducting scalability testing and performance benchmarking on multi-node systems.
- Understanding of networking protocols and high-performance interconnect technologies such as RDMA, InfiniBand, or RoCE.
- Contributions to database engines, storage systems, operating systems, or distributed infrastructure platforms.
What You'll Work On
Examples of areas where CMTS engineers contribute include:
- Global Cache Services (GCS)
- Global Enqueue Services (GES)
- Cluster synchronization and coordination
- Node membership and failover mechanisms
- High availability and continuous operations
- Performance optimization of Cache Fusion and cluster messaging
- Scalability improvements for large RAC clusters and cloud deployments
- Benchmarking and performance characterization of new database features
- Investigation and resolution of complex performance and scalability issues
- RAC integration with Oracle Cloud Infrastructure
- Autonomous Database infrastructure enhancements
- Next-generation clustered database architectures
Success Profile
The ideal candidate is a highly technical engineer who enjoys solving complex distributed systems problems and is passionate about building highly available, scalable, and high-performance database technologies. You are equally comfortable designing new functionality, diagnosing difficult performance issues, and driving architectural improvements that enable Oracle RAC to scale efficiently across increasingly large and demanding deployments.
