High-Performance Optimization Expert

As a key member of our high-performance team, you will play a crucial role in designing and implementing robust performance testing frameworks and scalable infrastructure.

You'll work closely with cross-functional teams to embed performance best practices throughout the development lifecycle. Your impact will drive continuous improvement through automation, performance metrics, and real-time dashboards.

Key Responsibilities:

• Design, build, and maintain performance testing frameworks and tools
• Analyze system bottlenecks and latency under load
• Optimize services for scalability and cloud efficiency
• Collaborate with R&D and product teams on performance design reviews
• Implement automation and CI-friendly performance test pipelines
• Deliver insights via dashboards, KPIs, and metrics-driven analysis

Requirements:

Qualifications:

• Bachelor's degree in Computer Science, Software Engineering, or related field
• 3+ years hands-on experience in performance/load testing, benchmarking, and profiling of distributed systems
• Solid experience with load testing tools such as k6, Gatling, or JMeter (k6 preferred)
• Strong proficiency in at least one scripting or programming language: JavaScript, Go, Python, or Java
• Deep understanding of performance metrics: throughput, latency, percentiles, resource utilization, etc.
• Practical experience with monitoring, observability, and profiling tools: Prometheus, Grafana, Elastic, Dynatrace, or similar
• Proven experience analyzing performance at multiple layers: application, network, infrastructure, container/runtime
• Experience with CI/CD pipelines, test automation integration, and tools like Jenkins or GitHub Actions
• Hands-on knowledge of Cloud platforms (AWS, Azure, GCP) and Kubernetes runtime environments
• Ability to derive insights from traces, logs, and profiling data, and translate them into actionable optimizations
• Strong debugging and troubleshooting skills across the full stack
• Ability to define KPIs, build dashboards, and communicate performance trends to developers and stakeholders
• Familiarity with SSE, gRPC, WebSockets, or high-concurrency APIs is a plus
• Understanding of network-level constraints, such as NAT limitations and connection scaling, is an advantage
• A mindset for engineering excellence, clean testing code, and test repeatability
• Self-motivated, curious, and driven to continuously improve system performance
• Fluent English (written and verbal) and excellent communication skills
