Job description

Design robust performance testing strategies, including test plans, KPIs, SLAs, and performance models tailored for IoT ingestion, SCADA polling, dashboards, alerting, and reporting.
Configure performance test environments that closely replicate on-premises and Azure production settings.
Develop and maintain performance test scripts using tools like JMeter, k6, Locust, and Gatling.
Simulate large-scale workloads encompassing 10,000+ device connections, MQTT/OPC UA traffic, high-frequency sensor data, and SCADA HMI activity.
Integrate automated performance tests into Azure DevOps CI/CD pipelines to streamline processes.
Monitor and analyze system performance with tools such as Azure Monitor, Application Insights, Log Analytics, and Grafana.
Identify and address bottlenecks, analyzing CPU, memory, database latency, IoT Hub throttling, network performance, and end-to-end latency.
Prepare detailed performance reports, capacity recommendations, and SLA pass/fail results for engineering teams and client stakeholders.
Collaborate with developers, DevOps, and infrastructure teams to enhance application, database, and cloud performance.
Support UAT, major releases, client deployments, and post-release hypercare activities.
Establish and promote performance testing standards, templates, processes, and best practices across the organization.
Ensure all performance testing is conducted safely, especially with systems linked to live OT/SCADA environments.
