Senior Performance Engineers are responsible for optimizing production systems to support traffic growth and new products. Their duties include creating a best practice framework for performance monitoring, scalability, and dependency handling, as well as developing testing infrastructure for post-deployment of production. They are responsible for designing alerts and dashboards, addressing performance issues, conducting root-cause analysis, defining process architecture, and facilitating site reliability in determining requirements for product scalability. Senior Performance Engineers also develop training programs to mentor operation services personnel.
A senior test engineer is an individual who is responsible for developing and implementing cost-effective methods of testing and troubleshooting computer systems and equipment. Senior test engineers must assist junior engineers in developing test plans and conducting testing activities on complex systems to meet program requirements.
