Qualifications

5+ years of experience in performance testing, with proven experience designing performance strategies and not only executing test scripts.
Strong hands-on experience with JMeter, k6, Locust, Gatling, or similar performance testing tools.
Experience testing cloud-native, hybrid, and enterprise-scale systems, preferably in Microsoft Azure environments.
Understanding of IoT and SCADA systems, including device telemetry, MQTT, OPC UA, PLCs, real-time dashboards, and time-series data.
Experience working with high-volume or high-cardinality data and real-time performance requirements.
Strong analytical and troubleshooting skills, with the ability to interpret logs, metrics, and traces to identify root causes.
Experience with performance monitoring and observability tools.
Strong communication and reporting skills, with the ability to present technical findings to both technical and non-technical stakeholders.
Experience with Azure IoT Hub and Azure Data Explorer or similar time-series databases.
Knowledge of Kubernetes, Docker, and Terraform for performance test environment setup.

Responsibilities

Design performance testing strategies, test plans, KPIs, SLAs, and performance models for IoT ingestion, SCADA polling, dashboards, alerting, and reporting.
Configure performance test environments that replicate on-premises and Azure production environments.
Develop and maintain performance test scripts using JMeter, k6, Locust, Gatling, or similar tools.
Simulate large-scale workloads, including 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.
Monitor and analyze system performance using Azure Monitor, Application Insights, Log Analytics, Grafana, and similar tools.
Identify bottlenecks and analyze CPU, memory, database latency, IoT Hub throttling, network performance, and end-to-end latency.
Prepare performance reports, capacity recommendations, and SLA pass/fail results for engineering teams and client stakeholders.
Work closely with developers, DevOps, and infrastructure teams to improve application, database, and cloud performance.
Establish performance testing standards, templates, processes, and best practices for the organization.
