QA Architect

As a Principal Architect for Quality Engineering Frameworks at Infinia, you will play a crucial role in owning the technical vision, architecture, and evolution of the Python/pytest automation platform. Your responsibilities will include transforming automation into a scalable, developer-centric service that validates correctness, performance, resilience, and real-world behavior across highly distributed systems. **Role Overview:** In this hands-on role as a staff-plus individual contributor, you will have broad organizational influence. You will be expected to write and review production-quality code, define architectural standards, and mentor engineers across QE and Development teams. **Key Responsibilities:** - **Framework Architecture:** - Own the end-to-end architecture and technical direction of the Python/pytest automation framework. - Define architectural standards, extension points, and long-term evolution. - Ensure the framework scales with system complexity and organizational growth. - **Automation Platform and Reusable Tooling:** - Design and implement reusable Python libraries, pytest fixtures, and plugins. - Provide a self-service automation platform with a clear, opinionated paved road for developers. - Maintain strict standards for determinism, readability, and maintainability. - **System Correctness, POSIX, S3, and Storage Validation:** - Architect automation validating POSIX filesystem semantics, including metadata operations, locking, concurrency, permissions, and consistency. - Validate object, block, and networked storage systems including S3-compatible object storage, NVMe/iSCSI, and NFS/SMB. - Ensure correctness under failure scenarios, scale, and sustained load. - **Distributed Systems, Resilience, and Scale:** - Design automation covering clustering behavior, membership changes, failover, and recovery. - Validate horizontal and elastic scaling in real deployment conditions. - Extend automation into repeatable resilience and chaos testing beyond simple failure injection. - **Performance and Stress Testing:** - Integrate performance and stress testing into CI/CD pipelines using tools such as fio, IOR, Minio Warp, Mongoose, and MLPerf. - Validate throughput, latency, and stability and continuously detect performance regressions. - **Cloud and Execution Environments:** - Architect automation to execute consistently across AWS and GCP. - Support execution on Kubernetes, Docker, hypervisors, and bare-metal systems. - Validate cloud-specific behaviors including autoscaling, contention, networking variability, and zonal failure modes. - **Telemetry-Driven Validation:** - Integrate automation with Grafana, Prometheus, and ELK for system behavior validation. - Enable deep diagnostics and root-cause analysis from automated runs. **Qualifications Required:** - Proven experience in architecting and developing automation frameworks, particularly with Python/pytest. - Strong understanding of distributed systems, storage systems, and cloud environments. - Experience with performance testing, resilience testing, and system validation. - Familiarity with CI/CD pipelines and tools like Grafana, Prometheus, and ELK. - Excellent leadership and communication skills to mentor and collaborate with team members effectively.
