The Vision: Turning the Database into the Cloud

Most companies treat the database as a passive storage bin. At Oracle, we’re doing the opposite. We are building a next-generation platform where application logic lives directly alongside data.

Our mission is to eliminate the "data tax", the latency and complexity of moving data to the code by running modern languages and microservices directly within the database engine. We are essentially re-architecting the database to be the ultimate cloud platform for data-centric applications.

Why Oracle Database Technologies

We offer the best of both worlds: the massive scale and stability of a global tech giant, and the technical "greenfield" feel of a high-end research lab.

* Complex Systems: Work with GraalOS and GraalVM—technologies that are literally redefining what’s possible in systems engineering.
* Zurich Life: Work from our world-class hub in Zurich, consistently ranked as one of the best cities in the world for quality of life and engineering talent.
* Diversity & Inclusion: We believe that innovation is powered by different perspectives. We are committed to an inclusive environment where engineers of all backgrounds, genders, and identities can do their best work. We don't just value diversity; we need it to solve the problems we’re tackling.

What You'll Do

The Role: Advanced Engineering With Exciting Technology

As a Senior Software Engineer (IC3) in Oracle's Database Technologies Division, you will work at the intersection of database internals, virtualization, and compiler technology.

Your work will leverage GraalOS (our state-of-the-art in-process virtualization) to create a high-performance runtime for functions, microservices, and AI-driven logic.

* Design & Build: Develop major features for the Oracle Database that enable deep integration of application logic and data management.
* Innovate: Transition research-level concepts in virtualization and systems programming into production-grade cloud services.
* Optimize: Solve "impossible" performance bottlenecks at the low-level intersection of the OS, the hardware, and the database kernel.
* Impact: Your code will run on the enterprise systems that power the world’s largest banks, hospitals, and governments.

What You'll Bring

We are looking for "systems people" - engineers who aren't afraid to dive into the kernel, look at assembly, or debug a complex race condition in a distributed system.

The Experience: You have a solid background as a Software Engineer (mid to senior level). We also highly value MSc or PhD graduates who have focused their research on systems.

The Toolkit: You have deep knowledge in at least one of these areas:
* Database System Internals

* Computer Security

The Passion: You are excited by low-level systems engineering. You care about how memory is managed, how threads are scheduled, and how data moves through a CPU.

Location: You are either based in or ready to relocate to Zurich, Switzerland.
