• Weigh architectural trade-offs and apply synchronous and asynchronous design patterns.
• Monitor, assess, and analyze the holistic performance of the application with benchmarking tools.
• Identify bottlenecks, lead root cause analysis, collaborate with developers, automate processes, and ensure proper tools to meet performance requirements from design to deployment.
• Own and enhance performance coverage by consulting with developers to identify areas for improvement and expansion.
• Investigate and diagnose performance issues to identify root causes.
• Clearly document performance results and share actionable insights with developers.
• Develop datasets and workloads that accurately represent the production environment.
• Analyze CPU utilization, memory usage, network usage, garbage collection, and DB reports to verify application performance.
• Research and implement best practices, methodologies, and tools for performance testing.
• Explore and pitch product ideas and tech initiatives with cross-functional teams.
• Drive UI performance optimization and ensure cross-browser compatibility.
• Stay current with emerging technologies and trends and evaluate their potential for adoption.
• Mentor junior team members and contribute to team growth and development.

• Proficiency in profiling all layers of the technology stack (software, OS, network) and optimizing complex applications.
• Expertise in Cloud & Container Ecosystem (Azure, Docker, Kubernetes).

Preferred Qualifications

• Master’s degree in computer science or related field.
• Hands-on experience with Chaos Engineering tools like Gremlin.
• Hands-on experience with caching layer performance tuning.
• 5+ years of experience in performance engineering, with a proven track record of optimizing system performance across complex environments.
• Excellent communication and collaboration skills, with the ability to work effectively with developers, product managers, and business stakeholders.
• Deep expertise in database performance tuning, with a focus on optimizing complex SQL queries.
• Strong analytical skills for identifying root causes of performance issues and resolving code-level bottlenecks.
