Software Developer 3

Oracle•Redwood City, CA

About The Position

Oracle is leading the digital revolution. We are empowering nearly half a million businesses to thrive in the age of skyrocketing connections. Join us and play an instrumental role in masterminding the software that will have a truly global impact. Oracle is building the next-generation B2B Marketing Platform, and our team is focused on high-scale, real-time streaming data capabilities that power ingestion, transformation, augmentation, and access to customer data across multiple sources and clients. We build and operate streaming data pipelines, manage Flink infrastructure, and own a high-scale data access layer that enables fast, consistent access patterns for downstream services. We work in a highly agile environment and partner closely across engineering, product, and operations to deliver resilient, secure, and performant platform services. As a Senior Software Developer (IC3), you will design, develop, troubleshoot, and debug software programs for databases, applications, tools, and distributed systems. You’ll contribute to architecture and implementation, help drive engineering best practices, and provide technical leadership to other developers. Duties are varied and complex, requiring independent judgment and strong ownership. What You’ll Do Solve the kind of enthralling, high-scale challenges that engineers live for. As a Senior Software Developer (IC3) you will:

Requirements

Production experience building data processing systems, specifically Apache Flink and Kafka / stream-processing architectures.
Production experience debugging highly distributed systems, with a track record of resolving data processing and pipeline reliability issues.
Working knowledge and hands-on experience with OpenSearch (indexing/query patterns, performance tuning, operational considerations).
Experience with Redis caching (cache-aside patterns, TTL strategy, consistency tradeoffs, performance troubleshooting).
Ability to lead a small project end-to-end: requirements clarification, design, implementation, testing, deployment, and operational handoff; able to mentor/guide other engineers as needed.

Nice To Haves

Strong Java/Scala (and/or Python) development experience in backend or distributed systems.
Experience running Flink at scale (state management, checkpoints/savepoints, upgrades, job tuning).
Familiarity with observability tooling (metrics, logging, tracing) and on-call/operational best practices.
Cloud-native development experience (containers, CI/CD) and secure engineering practices.

Responsibilities

Build and evolve streaming data pipelines for ingestion, transformation, enrichment/augmentation, and delivery using Flink and Kafka, ensuring correctness, low latency, and reliability at scale.
Operate and troubleshoot distributed production systems, diagnosing data-processing issues end-to-end (e.g., lag, backpressure, state issues, schema/serialization problems) and driving incidents to resolution with strong root-cause analysis.
Design and implement platform capabilities in our data access layer and supporting services (APIs, storage/indexing, caching), improving performance, scalability, and maintainability while working in an agile, iterative delivery model.
