Senior Software Engineer, Core Infrastructure

Job Description

About the role
Oracle Cloud Infrastructure (OCI) is seeking a Senior Software Engineer to build software for a new Data Processing Unit (DPU) platform spanning networking and storage. You will work on problems such as efficient packet processing, moving data between host and DPU, and maintaining correct behavior under load and failures.

You will independently own well-defined features or bounded components, including detailed design, implementation, testing, and integration. You will make implementation decisions within agreed interfaces and architectural boundaries, partnering with experienced engineers when a change affects the broader system. Storage familiarity is required; deeper storage experience is especially valuable.
What you will do

• Own feature delivery. Turn defined objectives into detailed designs, maintainable code, tests, and integrated features. Identify dependencies and communicate progress and risks early.
• Build efficient data paths. Implement packet forwarding, encapsulation, virtual networking, policy, or storage integration features. Evaluate correctness and resource usage under representative traffic conditions.
• Make sound implementation decisions. Choose data structures, synchronization, and memory management approaches within the component architecture. Explain tradeoffs in design and code reviews.
• Measure performance. Use benchmarks, packet captures, and profiling tools to diagnose throughput, latency, CPU, and memory issues. Demonstrate improvements with repeatable measurements.
• 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. Diagnose and fix issues in the features you own during integration and production support.
• Collaborate and share expertise. Review code, document interfaces and debugging findings, and help teammates solve problems. Raise proposals when local improvements require architectural changes.
• Use AI tools responsibly. Review and validate AI outputs used in coding, testing, debugging, and documentation. Remain accountable for correctness and share uses that reduce repetitive work and improve the team's experience.

Responsibilities

Required 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.

Preferred qualifications

Experience in one or more of the following areas is valuable. Experience with every listed technology is not required.

• Packet processing. DPDK or another user-space packet processing framework; traffic generators, packet captures, or network benchmarks.
• DPU acceleration. Exposure to DPUs, SmartNICs, AMD Pensando, NVIDIA BlueField/DOCA, P4, or comparable technologies.
• Storage. Storage software, block storage, NVMe, NVMe over Fabrics, RDMA, or storage virtualization.
• Hardware and validation. PCIe, DMA, SR-IOV, zero-copy techniques, hardware offload, load testing, or failure recovery testing.

What success looks like

You will deliver reliable features with clear detailed designs, meaningful tests, and measured performance. You will become a dependable owner of your components, resolve issues systematically, and contribute useful improvements to team practices.
Why join us

Join early enough to influence implementation choices and see your work reach production. You will have meaningful ownership, access to experienced technical partners, and opportunities to deepen your expertise across networking, storage, and hardware acceleration.
