Staff Engineer

Responsibilities

• Design and execute functional, integration, and end-to-end test strategies for CloudSecure features.
• Build and maintain scalable API, UI, and end-to-end automation frameworks.
• Validate cloud security workflows including resource discovery, policy computation, flow ingestion, visualization, and compliance across AWS, Azure, and GCP.
• Partner with engineering and product teams on acceptance criteria, testability, and shift-left quality practices.
• Own defect triage, root cause analysis, and release readiness for assigned feature areas.
• Design and execute performance, scalability, stress, peak-load, and long-running endurance tests for enterprise-scale environments.
• Build automated performance benchmarks and regression suites for latency, throughput, and resource-utilization regressions.
• Design chaos engineering experiments involving database failovers, Kafka failures and lag, network partitions, cloud API throttling, pod failures, and out-of-memory scenarios.
• Validate graceful degradation, fault tolerance, recovery, and high availability across distributed services.
• Own CI/CD quality gates and improve automation reliability, execution time, and release confidence.
• Drive cross-module integration testing across User Console, CloudSecure services, Policy Compute Engine, and supporting platform services.
• Develop tooling for self-service test environments, test data, and automation execution.

• Strong understanding of distributed systems, REST APIs, Kubernetes, and cloud-native architectures.
• Ability to debug application code and identify root causes in close collaboration with developers.
• Preferred experience with performance and load testing tools including k6, Locust, JMeter, or Gatling.
• Preferred experience profiling distributed-system performance and identifying bottlenecks.
• Preferred familiarity with Grafana, Prometheus, Datadog, or OpenTelemetry.
• Preferred experience with chaos engineering tools such as Litmus, Gremlin, or Chaos Monkey.
• Preferred experience with Kubernetes, Docker, and Terraform.
• Understanding of network security, segmentation, firewall policies, and cloud networking is preferred.
• Preferred experience testing enterprise-scale, multi-tenant SaaS platforms.
• Must be able to serve in compliance with applicable U.S. export controls.

Benefits

• On-site five days a week at Illumio's Sunnyvale, California headquarters.
