Job summary

Fractile seeks a senior system-test engineer to own the architecture and execution of system-level test strategies for AI accelerator servers. You will oversee manufacturing-grade tests across hardware, firmware, and software interfaces, ensuring scalable, reliable processes and effective diagnostics.

Lead test development for high-throughput rack deployments and field diagnostics, collaborating with hardware, OS, and platform teams to embed testability and maintainability throughout the stack.

Qualifications

• 8+ years of experience in system-level or server platform validation, test engineering, or platform QA.
• Strong understanding of server architectures, BMC/OpenBMC/Redfish, Linux-based systems, and hardware/firmware interactions.
• Experience validating or testing high-speed IO subsystems (PCIe Gen4/5/6 or comparable serial fabrics).
• Experience leading test development for manufacturing or field diagnostics in large-scale server, storage, or networking systems.
• Ability to lead teams, manage external vendors, and drive cross-functional test initiatives.
• Strong skills in system debug, log analysis, failure isolation, and multi-component testing.
• Familiarity with liquid-cooled or thermally complex server designs.

Responsibilities

• Define the system-level test strategy for an AI accelerator server platform with hundreds of PCIe Gen6 links, liquid cooling, and heterogeneous compute/management subsystems.
• Lead the design and implementation of structural, functional, stress and reliability tests executed on servers and full-rack configurations.
• Manage the deployment of system test suites in manufacturing environments, ensuring high throughput, repeatability, failure isolation, and secure automation workflows.
• Define and deliver test solutions for field diagnostics, repair, and maintenance—including remote test suites, health-check routines, failure triage, and component-level isolation.
• Collaborate with hardware, firmware, OS, and platform teams to embed system-level test and diagnostic functions and ensure testability across the server and rack.
• Drive test integration into OpenBMC, Redfish, and platform-management frameworks; validate BMC/RMC test and maintenance behaviors, telemetry, and hardware-control functions.
• Develop test automation infrastructure and tooling that spans multiple OS environments (embedded Linux on BMC/RMCs, server-class Linux on host CPUs).
• Partner with rack integration teams to define tests executed at rack-level assembly.
• Establish KPIs and dashboards for system test coverage, yield, throughput, failure rates, and field return correlation.
• Manage internal test engineering team and relevant external partners.
• Own system test documentation: test specifications, factory/field procedures, debug guides, and integration handbooks.
