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.

Responsibilities

Key Responsibilities
System Design & Architecture - System Scalability:
–Lead the development and implementation, and begin to architect, components of scalable distributed systems that support horizontal and vertical scaling to meet system demands, including leveraging distributed state management tools. 
–Optimize code and/or systems for large-scale data processing and high-throughput requirements to support hyper-scale systems.

–Design systems to scale with elasticity (e.g., effectively scaling both up and down). 
–Leverage data plane platforms to effectively handle large-scale data retrieval, storage, and processing. 
–Design performance and load testing.
System Design & Architecture - System Reliability Design:
–Build and design fault-tolerant components and systems capable of withstanding in-service updates by implementing redundancy, replication, and automatic failover mechanisms. 
–Design systems to effectively handle service disruptions (e.g., network partitions) by prioritizing consistency, availability, or partition tolerance. 
–Implement and optimize approaches to handle network unreliability, including load-shedding, throttling, and rate-limiting. 
–Design components and systems that are durable and adhere to service level objectives (SLOs), setting expectations for availability and durability of other computing services within the department.
System Design & Architecture - System Reliability Performance:
–Define key performance indicators (KPIs) and telemetry to identify gaps or issues in running systems. 
–Build and customize moderately complex dashboards, telemetry systems, and alerting mechanisms to proactively monitor components and system health..
System Design & Architecture - Correctness / Availability:
–Design and implement functional and correctness requirements for feature sets and/or systems in new or existing systems. 
–Design complex test scenarios (e.g., fault-injection, brown-out) to evaluate system correctness. 
–Implement data replication and synchronization techniques to maintain data integrity and availability.
Operational Troubleshooting & Incident Management:
–Take a proactive role in diagnosing, debugging, and resolving issues in active components and systems to support ongoing operation, and mentor others in these processes. 
–Implement strategies to prevent interruptions, ensuring no maintenance windows are required for customers and users when resolving issues. 
–Maintain expertise in owned components and systems to ensure effective troubleshooting and performance. 
–Meet operational readiness expectations through design and implementation. 
–Serve in operational support rotations, providing guidance in incident response and root cause investigations.
Compliance & Security:
–Implement robust security measures to protect data and applications in multi-tenant environments, including encryption techniques and access controls. 
–Execute remediation plans to address identified security gaps. 
–Ensure cloud infrastructure is in compliance with industry standards and regulations and that documentation is up to date.
Automation & Change Management:
–Develop and maintain automation scripts and tools (e.g., Infrastructure as Code (IaC)) to manage cloud infrastructure. 
–Create and adhere to change management plans for patching, updating, and rolling back applications, and begin designing systems and components to allow for automation of these processes.

Core Responsibilities
Planning & Execution:
–Manages and coordinates moderately complex tasks, monitoring timelines and deliverables to ensure timely completion and adherence to requirements for a moderately-sized project or initiative.
