As part of our growing engineering organization, you'll design and build innovative systems from the ground up, influence cross-team architecture, and mentor others. This is a high-impact role where you'll help shape Oracle's next generation of cloud infrastructure.

We're building next-generation distributed systems in the cloud. To succeed in this role, you'll need prior cloud experience (OCI, AWS, Azure, or GCP) and the ability to apply it to complex, large-scale environments.

  • Solid knowledge of networking protocols (TCP/IP, HTTP) and architectures
  • Hands-on experience with databases (SQL/NoSQL), storage systems, and cloud persistence technologies
  • Deep familiarity with Linux environments
  • Proven troubleshooting and performance optimization skills
  • Experience with virtualization and containerization (Docker, Kubernetes) is a plus

Preferred Skills

  • Proven track record building resilient cloud services at scale
  • Experience with cross-cloud or multicloud development
  • Familiarity with CI/CD tools, observability, and secure cloud operations
  • Strong collaboration skills across remote and distributed teams
  • If you're passionate about solving complex infrastructure problems, building global-scale systems, and working with top engineers in the industry—apply now and be part of shaping the future of cloud at Oracle.
Responsibilities

As a Principal Software Developer within OCI, your responsibilities will include setting up development pipelines and deploying applications into development, test, and production environments. You will develop Infrastructure as Code using Terraform and work with Kubernetes for container orchestration and scaling of distributed applications.

  • Lead software design and development for major components of OCI infrastructure
  • Define and evolve engineering practices and technical standards
  • Collaborate with teams across Oracle to deliver integrated, scalable solutions
  • Dive deep into performance bottlenecks, security, and system design
