We are looking for a skilled Server-Side End-to-End QA Engineer to join the client’s QA team and take ownership of quality across the full server-side flow of the product. This role focuses on validating client’s distributed backend system, which ingests telemetry from millions of endpoint sensors, processes security events, applies detection logic, and exposes results through APIs and UI. You will ensure that the system behaves correctly, reliably, and at scale across real production-like environments.

  • Own end-to-end testing of client’s backend services (cloud)
  • Design and execute test scenarios covering full data flows from sensor ingestion through detection, storage, and response
  • Validate inter-service communication across microservices and distributed components
  • Test API contracts, backward compatibility, and cross-version interoperability
  • Validate system behavior under partial failures such as service restarts, network partitions, and degraded dependencies
  • Execute functional, regression, and exploratory testing across backend services
  • Perform data validation across databases, queues, caches, and analytics layers
  • Analyze logs, metrics, and traces to identify root causes of system-level issues
  • Validate fixes and participate in release readiness and go/no-go decisions
  • Collaborate closely with backend engineers, DevOps, and product teams
Required Qualifications:
  • Strong experience testing server-side systems and distributed architectures
  • Understanding of microservices, asynchronous processing, and event-driven systems
  • Experience with APIs and service-to-service communication
  • Familiarity with message brokers (Kafka, RabbitMQ, etc), queues, or streaming systems
  • Experience validating data in: Relational databases, NoSQL / key-value stores
  • Ability to write SQL and data validation queries
  • Understanding of data consistency, retention, and lifecycle
  • Strong system-level thinking and attention to detail
  • Ability to work independently and take ownership of quality
  • Experience with end-to-end system testing
  • Familiarity with CI/CD pipelines and automated testing
  • Experience with scripting or automation (Python, Bash, PowerShell, etc.)

  • Comfortable working across multiple teams and disciplines
Nice To Have:
  • Experience with cloud environments (AWS, GCP, OCI, or similar)
  • Familiarity with deployment strategies such as blue-green or canary
  • Experience testing cybersecurity products, EDR, or large-scale data platforms
