Illumio is seeking a Senior Quality Engineer to join the CloudSecure team, responsible for ensuring enterprise-grade cloud security at scale across AWS, Azure, and GCP. This role combines product quality automation with quality engineering and infrastructure validation, split roughly 50/50.
In the product quality and automation domain, you'll design and execute comprehensive functional, integration, and end-to-end test strategies for CloudSecure features. You'll 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. You'll partner with engineering and product teams to define acceptance criteria, improve testability, and drive shift-left quality practices. You'll own defect triage, root cause analysis, and release readiness for your feature areas.
In quality engineering and infrastructure, you'll design and execute large-scale performance and scalability tests simulating enterprise customer environments with thousands of workloads, hundreds of VPCs/VNETs, and millions of flow records. You'll build automated performance benchmarks and regression suites to detect latency, throughput, and resource utilization regressions. You'll validate system behavior under stress, peak load, and long-running endurance scenarios, and design chaos engineering experiments including database failovers, Kafka failures, network partitions, cloud API throttling, and pod failures. You'll validate graceful degradation, fault tolerance, recovery, and high availability across distributed services, own quality gates within CI/CD, and drive cross-module integration testing. You'll also develop tooling that enables developers to self-serve test environments, test data, and automation execution.
Required qualifications include a Bachelor's in Computer Science or equivalent, 3+ years building automation for SaaS or cloud-native distributed systems, strong programming skills in Python, Go, JavaScript, or similar, hands-on experience with automation frameworks such as Cypress, Playwright, or Pytest, experience designing automation for APIs, UI, and distributed microservices, hands-on experience with AWS, Azure, or GCP including networking and security constructs, experience with CI/CD pipelines, and strong understanding of distributed systems, REST APIs, Kubernetes, and cloud-native architectures. You should be able to debug application code and work closely with developers to identify root causes.
Nice-to-have skills include experience with performance and load testing tools, application performance profiling, observability platforms, chaos engineering tools, Kubernetes and Docker, Terraform, network security and segmentation knowledge, and experience testing enterprise-scale multi-tenant SaaS platforms.
The role requires 5 on-site days per week at Illumio's Sunnyvale, CA headquarters. This position involves access to software subject to U.S. export controls.
