Sr. Engineer, Core Infrastructure

Oracle•Seattle, WA

78d•$114,600 - $234,600

About The Position

Within Oracle Cloud Infrastructure (OCI), the Technical Strategy & Oversight organization builds foundational systems for demanding cloud services. Autonomous OCI is a greenfield initiative to create a cloud platform that operates and scales with less manual work, making services fast, resilient, and self-healing by default. The goal is to support growth to thousands of regions without increasing operations teams at the same rate. As a Member of Technical Staff, the Sr. Engineer will help shape Lightweight Infrastructure (LWI), a next-generation runtime and platform layer for compute, storage, networking, identity, observability, and governance. The role develops and helps architect scalable, elastic distributed-system components; defines scalability and reliability requirements; and optimizes systems for high-throughput, hyperscale workloads. It also designs fault-tolerant and in-service-upgradable systems, establishes telemetry and monitoring, validates correctness and durability, and diagnoses production issues. The position also covers operational readiness and incident support, security and compliance, and automation for infrastructure changes. The engineer provides technical leadership through mentoring, reviews, and collaboration, and helps coordinate moderately complex projects and initiatives.

Requirements

BS/MS in Computer Science or equivalent practical experience.
6–10+ years of software engineering experience building highly available, scalable distributed systems or cloud infrastructure.
Strong programming skills in Java, Go, Rust, C/C++, or a similar systems or backend language.
Deep experience in one or more core infrastructure areas: distributed systems, cloud control planes, management planes, scheduling, virtualization, storage, networking, security, reliability, or platform automation.
Ability to independently lead the design and delivery of complex services that are correct, resilient, observable, and easy to operate.
Strong understanding of failure handling, concurrency, asynchronous workflows, safe retries, and lifecycle management in distributed systems.
Strong debugging and problem-solving skills, including resolving complex production and performance issues.
Experience collaborating across teams and translating broad platform goals into clear designs and executable plans.
Ability to raise the technical bar through mentoring, design reviews, code reviews, and hands-on technical leadership.

Responsibilities

Lead development and implementation of components of scalable distributed systems, and begin architecting components that support horizontal and vertical scaling using distributed state management tools.
Define scalability requirements for owned components and ensure designs and implementations meet them.
Optimize code and systems for large-scale data processing and high-throughput workloads; use data-plane platforms for large-scale retrieval, storage, and processing.
Design elastic systems that can scale up and down, and design performance and load testing.
Build fault-tolerant systems that withstand in-service updates through redundancy, replication, and automatic failover.
Design systems to handle service disruptions such as network partitions, and apply consistency, availability, or partition-tolerance strategies as appropriate.
Handle network unreliability using techniques such as load-shedding, throttling, and rate-limiting; design durable components that meet SLOs.
Define KPIs and telemetry, and build dashboards and alerting to proactively monitor system health and identify performance or reliability gaps.
Design and implement functional and correctness requirements, complex validation scenarios such as fault injection and brownouts, and data replication and synchronization techniques.
Diagnose, debug, and resolve production issues; mentor others in troubleshooting; maintain expertise in owned systems; and support incident response and root-cause investigations in operational rotations.
Design and implement operational readiness and strategies to prevent customer-impacting maintenance windows.
Implement security measures for multi-tenant environments, including encryption and access controls; remediate security gaps and maintain compliance documentation.
Develop and maintain infrastructure automation, including IaC scripts and tools, and follow change-management plans for patching, updates, and rollbacks.
Coordinate moderately complex tasks and projects, monitor timelines and deliverables, delegate and prioritize work, and adjust plans when resources or timelines change.
Collaborate across teams and with stakeholders to align expectations and deliver solutions that meet their needs; listen to diverse perspectives and support inclusivity.
Analyze moderately complex problems, document problem-solving strategies, and escalate critical or unresolved issues with assessments and potential solutions.
Pursue ongoing learning, apply feedback and training, coach and mentor junior colleagues, and share knowledge across teams.
Recommend and help implement process improvements, solicit feedback, and evaluate their impact.
Participate in candidate interviews, assess candidates, and provide hiring recommendations.
