Principal Core Infrastructure Engineer

We are looking for IC3 Senior, IC4 Principal, and IC5 Lead Principal Core Infrastructure Engineers to help build Oracle Video’s advertising capabilities on OCI. The engineering scope spans new advertising orchestration services, integrations with advertising and media preparation partners, approval workflows, and enhancements to video ingestion, delivery, and playback. It also includes telemetry, reconciliation, metering and billing integration, load testing, and production readiness. Core technical requirements We are looking for strong software engineers who can build and operate reliable cloud services, with experience relevant to their level and assigned specialty: Production software development, sound programming fundamentals, and maintainable, well-tested code. Distributed systems, service APIs, data modeling, and third-party integrations. Asynchronous workflows, queues, retries, idempotency, and recovery from partial failures. Cloud infrastructure, deployment automation, observability, performance optimization, and troubleshooting. Security fundamentals, including tenant isolation, authorization, secrets management, and auditability. Ownership from design and implementation through testing, deployment, and production support. Clear written communication and effective collaboration across engineering, product, and partner teams. Expectations by level IC3 — Senior: Independently delivers and operates defined components or features, implements reliable integrations and failure handling, contributes to design and code reviews, and investigates production issues. IC4 — Principal: Owns complex services or subsystems end to end, translates ambiguous requirements into technical designs, makes architecture and reliability trade-offs, coordinates dependencies, and mentors engineers. IC5 — Lead Principal: Leads architecture and delivery across multiple services and teams, establishes shared contracts and engineering standards, resolves complex technical ambiguity, and aligns technical direction with product and operational needs. Specialist experience Depending on the position, we would value depth in backend and orchestration services, cloud platform engineering, data and measurement pipelines, media and playback systems, or reliability and performance engineering. We do not expect every candidate to cover all these specialties. AdTech, CDN, networking, and streaming knowledge are advantages, not mandatory selection criteria. Relevant examples include ad decisioning and tracking, VAST/VMAP, FreeWheel or similar platforms, caching and media distribution, Media over QUIC (MoQ), playback SDKs, and ad insertion. Experience with GenAI providers, creative asset workflows, and media preparation integrations is also valuable for relevant roles. Please include candidates from adjacent domains such as enterprise SaaS, cloud infrastructure, workflow platforms, data processing, and large-scale distributed systems. Strong engineering fundamentals, ownership, and the ability to learn the domain should take priority over familiarity with specific advertising or streaming technologies.
