Job summary

Oracle is seeking an experienced software engineer to own feature delivery for networking and storage‑oriented systems. You will design, implement, test, and optimize data paths, packet processing, and related components on Linux with a focus on performance and reliability.

You will collaborate with networking and storage teams, review code, and contribute to production readiness. The role emphasizes robust design decisions and careful instrumentation to improve throughput and latency.

Qualifications

• 3+ years of professional software engineering experience in systems or infrastructure software, including hands-on networking data plane development.
• Strong C or C++ skills, including debugging, memory management, and concurrent programming on Linux.
• Working knowledge of packet processing and networking fundamentals, including Ethernet, IP, TCP/UDP, routing, and switching.
• Experience implementing or debugging networking software such as forwarding, encapsulation, virtual switching, or network policy.
• Familiarity with the basic storage I/O path, latency, throughput, and failure handling, and ability to investigate issues with storage partners.
• Experience with automated testing, debugging or profiling tools, and using measurements to explain software behavior.
• Ability to independently deliver defined features, make detailed design decisions, and identify issues requiring broader architectural input.
• Clear technical communication and constructive collaboration in design discussions, code reviews, and integration work.
• A bachelor’s degree in Computer Science, Computer Engineering, or a related discipline, or equivalent practical experience.

Responsibilities

• Own feature delivery. Turn defined objectives into detailed designs, maintainable code, tests, and integrated features.
• Build efficient data paths. Implement packet forwarding, encapsulation, virtual networking, policy, or storage integration features.
• Make sound implementation decisions. Choose data structures, synchronization, and memory management approaches within the component architecture.
• Measure performance. Use benchmarks, packet captures, and profiling tools to diagnose throughput, latency, CPU, and memory issues.
• Connect networking and storage. Understand the basic storage I/O path and investigate how network behavior affects latency and throughput, working with networking and storage partners.
• Build for production. Add useful instrumentation, test error paths and recovery, and contribute to release validation.
• Collaborate and share expertise. Review code, document interfaces and debugging findings, and help teammates solve problems.
• Use AI tools responsibly. Review and validate AI outputs used in coding, testing, debugging, and documentation.
