Performance Engineer

The role

The Performance & Reliability team works cross-functionally to shape performance standards and drive optimization across services, APIs, and clients. You will plan and conduct performance tests, profile applications to identify bottlenecks, and recommend optimizations at code, database, and infrastructure levels.

What you will do

• Plan and conduct performance, load, stress, and soak tests for .NET Core microservices, React and React Native clients, SQL Server/Cosmos DB queries, and messaging systems.
• Profile services and applications to identify performance bottlenecks using tools like Perfview, dotTrace, Azure Monitor, and browser dev tools.
• Recommend and validate optimizations at code level, database level, and infrastructure level.
• Define and monitor performance budgets, SLOs/SLIs, and capacity plans for critical services.
• Work with Kubernetes/AKS teams on resource allocation, autoscaling strategies, and performance implications of deployments.
• Build and maintain performance dashboards and monitoring.
• Document performance best practices, anti-patterns, and decision trees to guide teams.

Required qualifications

• Hands-on experience with performance testing frameworks and tools (e.g., JMeter, k6, Locust, custom harnesses).
• Strong understanding of .NET Core runtime behavior: async patterns, TPL, thread pool, GC, memory allocation, and profiling techniques.
• Proficiency with .NET profiling tools: Perfview, dotTrace, Application Insights, or equivalent; ability to interpret ETW traces and metrics.
• Solid knowledge of SQL Server performance: query plans, indexing strategies, execution time analysis, and workload characterization.
• Familiarity with NoSQL performance tuning: Cosmos DB throughput, partitioning, consistency trade-offs, and cost modeling.
• Understanding of browser and mobile performance: network waterfall analysis, rendering performance, JavaScript profiling, and memory leaks.
• Exposure to Kubernetes resource management: CPU/memory requests and limits, QoS classes, and impact on performance.
• Knowledge of observability tools: Application Insights, Prometheus, Grafana, or similar; ability to correlate metrics and traces to identify root causes.
• 4–8 years of experience in performance engineering.
• Strong debugging and troubleshooting mindset.
• Experience collaborating with multiple teams across geographies.
• Excellent written and verbal communication.
