Job summary

IT Squarehub Global Services Corporation is seeking a Performance Test Lead to own performance strategies for an IoT & SCADA platform. You will design tests for high-volume ingestion, MQTT/OPC UA traffic, and real-time dashboards across on-premises and Azure environments.

The role requires 5+ years in performance testing with hands-on expertise in JMeter, k6, Locust, Gatling, and cloud-native testing. Strong analysis and reporting skills are essential for stakeholder communication.

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.
