Principal Core Infrastructure Engineer

The Oracle Cloud Infrastructure (OCI) team offers the opportunity to build and operate a suite of massive-scale, coordinated cloud services in a broadly distributed, multi-tenant cloud environment. OCI is committed to delivering cloud products that meet the needs of customers tackling some of the world’s biggest challenges.
OCI Infrastructure Delivery Engineering is a growing organization responsible for building services and tools that accelerate how OCI expands its compute and network capacity. Our platform supports the full lifecycle of data centers and their physical assets—from planning and design, through delivery and operation, to eventual decommissioning. It enables OCI to grow efficiently in existing regions and launch entirely new regions while meeting the high-capacity needs of large and hyperscale customers.
We are seeking a hands-on Principal Software Development Engineer to provide technical leadership for this greenfield platform. You will define architecture and engineering strategy for highly available, scalable services that manage physical assets throughout their lifecycle. You will solve ambiguous, cross-organizational problems; establish durable technical patterns; and raise the engineering bar while remaining deeply engaged in design, implementation, operational excellence, and customer outcomes.
This role combines broad autonomy with the opportunity to integrate with existing OCI systems through well-established contracts. You will influence the direction of a foundational platform at cloud scale and help shape how OCI continues to grow its global footprint.
About You
You are a hands-on cloud engineer and technical leader with a record of delivering high-scale, high-impact distributed systems.
You turn ambiguous business and infrastructure problems into clear technical strategy, phased execution plans, and measurable outcomes.
You care deeply about customers and consistently make sound trade-offs among reliability, security, velocity, simplicity, and cost.
You communicate complex technical concepts clearly to engineers, product leaders, and partner teams.
You set a high engineering bar, use data to build consensus, and constructively challenge assumptions.
You thrive in a fast-moving environment, take ownership across organizational boundaries, and mentor engineers at multiple levels.
Minimum Qualifications
BTech in Computer Science, Engineering, or a related field, or equivalent practical experience.
10+ years of professional software development experience, including substantial experience designing, shipping, and operating scalable, cloud-native distributed systems.
Demonstrated technical leadership for complex, multi-service initiatives, including architecture definition, technical roadmaps, design reviews, and delivery across multiple teams.
Strong proficiency in one or more high-level programming languages, preferably Go and/or Java; proficiency with scripting or automation languages such as Python.
Deep experience with distributed-systems fundamentals, microservice design patterns, service-to-service communication, data consistency, fault tolerance, and highly available service design.
Experience designing production services with robust observability, including service-level indicators/objectives, dashboards, metrics, alarms, capacity planning, and operational runbooks.
Proven production-operations experience, including incident response, root-cause analysis, on-call practices, and driving systemic reliability improvements.
Strong foundation in computer science concepts, including data structures, algorithms, concurrency, and programming paradigms.
Ability to author and communicate technical proposals, architecture documents, design specifications, and presentations for diverse audiences.
Experience mentoring engineers and improving engineering practices through code reviews, design reviews, and technical guidance.
