Senior Software Engineer - OpenShift/Kubernetes Performance and Scale

About the job

The Red Hat Performance and Scale Team is looking for an experienced senior level engineer to join our passionate global team to test, measure, analyze software performance and improve performance and scale of Red Hat OpenShift, the industry leading enterprise Kubernetes platform to help user workloads do more.

This role will focus on the scalability of Red Hat Openshift in our Managed Services (SaaS) offerings across AWS, Azure, GCP and other cloud providers. The Engineer will leverage their knowledge of systems performance in the cloud to theorize bottlenecks and limitations, devise test plans, execute workloads, collect and analyze data, and communicate findings. This role will require the ability to work cross-functionally with Product Management, Engineering Leadership, Development Teams and Quality Engineers to measure performance, clearly articulate findings and fix bottlenecks. Time will also be spent in collaboration with software engineering teams on bug fixes, code optimization and reduction of resource usage, and in developing open source tools for reliability and repeatability of tests.

Our team is global and diverse, and as such the location for this role is flexible. The Engineer may be located in one of our many global offices or may work permanently remotely.

What you will do?

• Work closely with management, product owners, developers, and quality engineers to understand product requirements and build suitable performance test plans to verify OpenShifts performance and scalability limits
• Develop sophisticated tests that perform user workload simulations through comprehensive end-to-end automation, leveraging custom built and state of the art open source tools and frameworks
• Improve existing frameworks for automated continuous performance testing and develop new features that help with automatic performance regression identification
• Deep dive into performance issues with the intent of discovering their root cause on complex distributed systems deployed on cloud infrastructure
• Design and develop monitoring and reporting tools to do performance and scale tests and analysis
• Document your research and results clearly and concisely, and communicate findings both internally and externally
