Define and lead the performance engineering strategy across high-availability, cloud-native telecom platforms. - Lead, train, and coordinate a distributed guild of SDETs across multiple feature teams, guiding them to build, maintain, and execute performance scripts (k6) within their fractional sprint capacity. - Design, develop, and evolve scalable backend performance frameworks using k6, Python, Java, or TypeScript, focusing entirely on APIs, databases, and infrastructure. - Implement and manage production traffic replay strategies (e.g., GoReplay) and complex multi-tenant test data generation to accurately recreate realistic production contention and load profiles. - Own and drive performance, load, stress, endurance, scalability, and resilience testing, including chaos engineering practices (e.g., using AWS Fault Injection Simulator). - Validate real-time communication systems, event-driven architectures (Kafka, RabbitMQ), and high-throughput distributed systems under production-like conditions. - Integrate performance testing into CI/CD pipelines, enabling continuous performance validation, shift-left practices, and automated PR blocking for latency degradation. - Leverage observability tooling (Grafana, CloudWatch, Coralogix, VictoriaMetrics, PMM) to monitor, analyse, and troubleshoot system performance. - , SLAs, SLOs, and error budgets aligned with business and system requirements. - to identify bottlenecks, validate database architectures (e.g., MySQL, Tungsten), and present evidence-based investment proposals. - across both legacy monolith systems (requiring integrated load testing) and modern microservices architectures. ###
Updated CV clearly demonstrating performance engineering leadership, cross-team coordination, AWS expertise, and backend automation frameworks. - Summary of performance testing frameworks, tools (e.g., k6, GoReplay), and CI/CD methodologies implemented. - Detailed examples of performance testing engagements (scale, environments, bottlenecks identified, business impact, improvements delivered). - Evidence of driving performance strategy, mentoring QA/SDET teams, and influencing architecture. #LI-KS1
