OCI is expanding its mission beyond the traditional boundaries of public cloud to include dedicated, hybrid and multi cloud, edge computing, and more.&nbsp;
At Technical Strategy and Oversight (TSO) organization, our mission is to support customer choice, transparency, and value when it comes to cloud infrastructure. We’re embarking on ambitious new initiatives such as building new innovative platforms, high performance primitives, frameworks to support OCI developers, and new container runtime that will allow us to run the full variety of OCI services, including our most demanding, high-performance, high-availability services.&nbsp; We’re also working on new ingenuities such as providing canonical implementation of core components for data planes through a data-plane runtime framework, developing a remote persistent storage solution with the latency and performance comparable to that of a local nVME drive, and developing standards and tools to identify critical performance improvements across OCI data-planes. We are hoping to enhance engineering efficiency by concentrating our expertise on building low level systems with high performance that can be adopted by our core cloud services across OCI.
As Oracle Cloud Infrastructure (OCI) continues its rapid expansion, we are seeking a skilled Software Engineer to join our newly established Cloud Performance Organization. This team plays a key role in addressing service inefficiencies, reducing cloud expenses, improving customer experience, and ensuring scalability.

Who are we looking for?
You have experience with the design of major features and launching them into production. You’ve built and operated high-scale public cloud services and have deep understanding of control plane architecture. You work on most projects and tasks independently and extend technical leadership to development teams.
In this role, you will enable development teams by driving design of major service components, working with engineering managers and TPMs, and providing direct guidance to more junior team members. You can go from high level system design, writing architectural documentation and driving engineering peer reviews to hands-on prototyping, code reviews and project bootstrapping.
You are technically strong and get a lot done. You can balance speed and quality with iteration and incremental improvements. You’ve made life easier for other developers and have motivated your teams to make both process and service improvements with your ability to automate and instrument your service. You understand operational excellence and how to instill a culture of high quality and customer focus.
