Job Description The ideal candidate does not wait for tasks. You see a gap, propose a solution, build consensus, and drive it to production. You bring strong computer-science fundamentals - data structures, algorithms, systems thinking - and you are comfortable operating across layers, from database engine internals to developer-facing API surfaces. Critically, you are not just an ideas person: you think in concepts and architectures, but you also write excellent code and ship it yourself. You also enjoy working directly with customers: we are actively migrating large workloads from MongoDB to Oracle, and this role involves understanding real-world usage, guiding adoption, and feeding customer insights back into the product. What You Will Own Next-gen document APIs - Design and ship new AI-enabled document interfaces that extend Oracle's multi-model story beyond today's SQL/JSON and MongoDB-compatible surface. SQL/JSON engine features - Architect and...

Job Description We're hiring a senior backend contractor to build and enhance a Java 17 event-driven service running in Azure AKS. The service consumes events from Azure Event Hubs, processes JSON payloads, stores metadata and operational data in Azure Data Explorer / ADX, stores large objects in ADLS, and exposes secure Search and Retrieval APIs. This is a Java / ADX / API role first, with Azure Event Hub experience also required. The right candidate has strong hands-on backend experience, can write and tune KQL for application-facing use cases, can build production APIs, and understands event-driven processing patterns. This is a senior IC feature-delivery role. The person should be able to work independently, provide design input, deliver production-quality code, validate performance, document decisions, and partner with the existing service SME and SRE team. This is not a primary SME, architect, platform engineer, or SRE role. The pay rate ranges based off the years of...
