Principal Software Engineer, Core Infrastructure

As Oracle Cloud Infrastructure (OCI) continues its rapid expansion, we are seeking a Principal Software Engineer (IC4) to join our Database and Host Automation team. This team builds the services and host agents that manage database infrastructure at scale, supporting provisioning, lifecycle management, live database migrations, maintenance, recovery, and region bootstrap.
This is a greenfield opportunity to design and build new automation services and secure host execution capabilities from the ground up. Your work will connect durable, fleet-wide orchestration with reliable database and operating system operations on individual hosts, improving availability, consistency, and operational safety while minimizing customer disruption.
You will independently drive complex projects from architecture through production operation, collaborating with database, infrastructure, and security teams. As a technical leader, you will guide design decisions, deliver robust software, mentor engineers, and improve engineering and operational practices across the broader organization. We are looking for someone with 7-10+ years of industry expereince.

Leads development and begins architecting components of scalable, elastic distributed systems. Defines and enforces scalability requirements for owned components; optimizes code and data paths for high‑throughput, hyper‑scale workloads; and leverages data plane platforms for large‑scale retrieval, storage, and processing. Designs fault‑tolerant, in‑service‑upgradable systems using redundancy, replication, failover, and policies for partitions, applying load‑shedding, throttling, and rate‑limiting to handle network unreliability while meeting SLOs. Establishes KPIs and telemetry; builds proactive dashboards and alerts; and designs complex validation (fault injection, brownouts), replication, and synchronization for correctness and durability. Proactively diagnoses and resolves production issues, mentors peers, and ensures operational readiness. Implements robust security controls, executes remediation, maintains compliance documentation, and develops IaC and automation that enable safe patching, updates, and rollbacks within change‑management plans.
