• Collaborate with development teams to diagnose and solve complex performance problems, providing technical analysis and tuning recommendations.
  

• Design, execute, and analyze performance testing including load, stress, and capacity planning to ensure system scalability and reliability.
  

• Monitor production systems and analyze performance metrics using APM tools (e.g., New Relic) to proactively identify and resolve bottlenecks.
  

• Utilize log indexing and querying tools such as Splunk for creating queries, regex, and dashboards to troubleshoot and resolve system performance issues.
  

• Analyze thread, heap, and TCP dumps using preferred tools for effective root-cause analysis.
  

• Use network monitoring tools like Wireshark, Extrahop, and Riverbed to troubleshoot and optimize network performance.
  

• Optimize application servers such as Tomcat, Node.js, and Spring Boot for peak performance.
  

• Collaborate with DevOps teams to improve deployment pipelines and automate performance testing.
  

• Stay current with emerging technologies and trends in performance engineering to provide technical guidance and leadership.
  

• Mentor junior engineers and share best practices related to performance optimization.

• Minimum of 5 years of experience in a performance engineering lead role.
  

• Minimum of 5 years of experience working with high-traffic, large-scale distributed systems, cloud platforms, and microservice architecture.
  

• Hands-on coding experience in at least one programming language: Java, Python, or Groovy.
  

• Strong knowledge of Netflix OSS or similar microservice architectures.
  

• Proficiency with APM tools (e.g., New Relic) for performance monitoring and analysis.
  

• Experience with log indexing tools like Splunk (queries, regex, dashboards).
  

• Familiarity with at least one performance testing tool, preferably JMeter.
  

• Experience with browser-side performance tools (e.g., Catchpoint, Lighthouse, Google Developer Tools).
  

• Performance tuning experience with Tomcat, Node.js, and Spring Boot.
  

• Strong understanding of non-functional requirements, performance testing processes, and defect tracking.
  

Preferred Qualifications

• Cloud DevOps experience, particularly with Kubernetes.
  

• Experience with network packet capture analysis using Wireshark or Cloud Shark.
