Software Engineer​/Architect - AI JSON​/MongoDB

Position: Software Engineer / Architect - AI JSON/MongoDB
** 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 Mongo

DB 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 Mongo

DB-compatible surface.

+  
** SQL/JSON engine features
- ** Architect and implement capabilities in query processing, indexing, optimization, and execution for JSON workloads formance is a first-class concern: you will profile, benchmark, and tune at every layer.

+  
** Oracle API for Mongo

DB
- ** Drive compatibility and feature parity so customers can migrate production workloads from Mongo

DB to Oracle with confidence. Work hands-on with migration teams and customers to identify gaps and prioritize fixes.

+  
** Customer engagement
- ** Partner directly with customers migrating to Oracle, understand their workloads, advise on best practices, and channel field insights into product improvements. Support escalations alongside Developer Operations.

+  
** Cross-cutting systems work
- ** Contribute to full-text search, compiler/language-design components, and interoperability across relational and document data models.

+  
** Technical leadership
- ** Mentor engineers, raise the quality bar through design reviews, and help translate ambiguous requirements into shippable plans.

** Why This Team*
* +  
** Greenfield opportunity
- ** Most of the roadmap is new. You will shape products, not just patch them.

+  
** AI-first trajectory
- ** Oracle's AI roadmap and OCI's strength as a cloud for AI workloads give this team outsized impact on how developers build intelligent applications.

+  
** Company momentum
- ** Oracle is making generational investments in AI infrastructure. This team is where that investment meets the data layer - a compelling place to build a career for the next decade.

+  
** Unique technical niche
- ** The Oracle API for Mongo

DB is one-of-a-kind: full Mongo

DB wire-protocol compatibility backed by a converged, enterprise-grade engine. Few teams anywhere work on this kind of problem.

+  
** Scale and reach
- ** Features you build ship to one of the largest installed bases in enterprise software.

+  
** Experienced peers
- ** You will collaborate with engineers who have decades of database-systems expertise.

+  
** Modern, AI-powered toolchain
- ** We work with a fully AI-enabled developer ecosystem:
Codex, AI-assisted code review, and intelligent testing. You will build with the same AI technologies you are building for.

** Responsibilities*
* + Strong foundations in database internals: storage, query processing, indexing, transactions, or distributed consensus.

+ Deep concern for performance - you instinctively profile, measure, and optimize, and you have experience tuning systems for latency, throughput, or resource efficiency.

+ Excellent programming skills with strong command of data structures, algorithms, and systems-level thinking. Experience in Java is expected; C, C++, Rust, or other systems languages are a plus.

+

Experience with compilers, language design, or query-language implementation.

+ Solid understanding of SQL and at least one document/No

SQL query model.

+ Hands-on experience with one or more of:
Oracle Database, Mongo

DB, Postgre

SQL, Dynamo

DB, Elasticsearch/Open Search, or Lucene.

+

Experience with full-text search engines or information retrieval (e.g., Lucene, Elasticsearch, Open Search) is a strong plus.

+ Comfort with ambiguity - you can take a vague customer need and turn it into a concrete…
