Principal Software Engineer, Core Infrastructure

Location: Santa Clara, CA, United States

About the role

Oracle Cloud Infrastructure (OCI) is seeking a Principal Software Engineer to build a new Data Processing Unit (DPU) platform spanning networking and storage. You will solve problems involving packet processing, host-to-DPU data movement, concurrency, and predictable performance under congestion and resource pressure.

You will be the technical owner of a substantial component: its architecture, interfaces, implementation, performance, and operational readiness. Starting from broad requirements, you will resolve design choices and drive delivery with partner engineers. You will propose changes that cross component boundaries and align them with subsystem owners. Deep networking expertise is essential; storage familiarity is required and substantial storage experience is especially valuable.

What you will do

• Own component architecture and delivery. Translate broad requirements into a component design and executable milestones. Make architectural and implementation decisions within agreed subsystem boundaries and carry the work through production.
• Design high-performance data paths. Build packet processing, network virtualization, forwarding, policy, or acceleration capabilities. Make deliberate choices about concurrency, buffering, memory ownership, and hardware interfaces.
• Define and coordinate interfaces. Establish component contracts with networking, storage, firmware, and hardware partners. Resolve dependencies and drive integration; escalate tradeoffs that require subsystem-wide decisions.
• Own component performance. Define representative benchmarks and performance targets. Investigate throughput, tail latency, CPU utilization, and memory efficiency, validating improvements under load and resource pressure.
• Evaluate storage interactions. Assess how component choices affect storage I/O performance, backpressure, and failure handling. Work with storage engineers to preserve correctness and reliable recovery.
• Deliver production readiness. Own component instrumentation, fault handling, compatibility, and upgrade behavior. Drive qualification and operational improvements, including difficult cross-layer debugging and production support.
• Guide engineers and engineering quality. Mentor engineers, lead component design reviews, and establish useful tests and performance regression checks. Help feature owners make independent decisions within the architecture.
• Improve responsible AI practices. Validate AI-assisted work and help the team adopt effective coding, testing, debugging, and documentation practices. Reduce repetitive work while preserving quality, accountability, and a sustainable engineering experience.
