About the role

Role focused on end-to-end performance, capacity, and observability for enterprise applications hosted on cloud infrastructure, with primary focus on Alibaba Cloud and AWS. Partners with architecture, database, and software engineering teams to ensure performance baselines, scalable systems, and rapid root-cause analysis in production and pre-production environments.

Responsibilities

  • Architect and execute comprehensive performance, load, stress, and soak test scenarios that accurately model real-world business concurrency, data volumes, and mixed-load endurance behavior.
  • Engineer and optimize cloud infrastructure primarily on Alibaba Cloud—with complementary depth on AWS—tuning Kubernetes clusters, autoscaling behaviors, compute/storage sizing, load balancers, and network latency.
  • Decompose and resolve latency across the complete request lifecycle, evaluating DNS, TLS, proxies, API gateways, application runtimes, and backend databases such as SAP HANA.
  • Build deep observability and automated monitoring solutions using metrics, logs, and distributed tracing platforms, incorporating AI-assisted tooling for anomaly detection and rapid root-cause analysis.
  • Optimize event-driven architectures and publish-subscribe pipelines on Kafka and enterprise event brokers, tuning topic partitioning, consumer lag, throughput, and backpressure handling.
  • Lead production incident investigations and post-go-live triage under tight deadlines, conducting thorough root cause analysis and collaborating with engineering teams to deploy lasting fixes.
  • Drive capacity and cost-to-performance modeling during architectural reviews, establishing performance benchmarks, entry/exit criteria, and automated test integration within continuous delivery pipelines.

Qualifications

  • Bachelor’s degree in Computer Science, Engineering, Mathematics, or equivalent practical experience.
  • 5+ years of experience in software or performance engineering, with demonstrated ownership of production performance for enterprise cloud applications.
  • Hands-on experience engineering and tuning cloud-hosted applications on Alibaba Cloud, along with production experience on AWS.
  • Experience configuring, sizing, and performance-tuning relational databases, including SAP HANA, on cloud infrastructure.
  • Experience modeling realistic workloads and conducting load, stress, soak, and capacity testing using tools such as Apache JMeter, k6, Gatling, or LoadRunner Enterprise.
  • Experience decomposing latency across complex multi-tier architectures and utilizing telemetry to identify root causes and quantify improvements.
  • Experience managing production performance incidents, including real-time triage and authoring detailed technical root cause analyses.
  • Professional working proficiency in English.
