You'll take systems from board and tray bring-up to full racks and multi-rack clusters, through L11 rack integration and deployment in the field. That includes accelerator compute trays, host servers, scale-up switches, and the components that tie them together: NICs, retimers, cables, power shelves, busbars, liquid cooling, and rack management. You'll build the plans, environments, and automation that prove our systems work at fleet scale. You'll partner with silicon, hardware, firmware, software, and manufacturing teams, along with our ODM and CM partners.\nWhat You'll Do\nCreate system validation plans for AI rack-scale systems at the board, tray, rack, and multi-rack cluster levels, through L11 rack integration\nBuild validation environments, including system diagnostics, stress and burn-in tests, workload-based tests, fleet health checks, and rack acceptance tests\nDevelop test automation that scales execution and automated triage across hundreds of racks and thousands of trays, including telemetry collection, results databases, and dashboards\nLead system and rack bring-up from first power-on of trays and racks through full validation, including interoperability across compute, host, and switch trays, power, thermal and performance characterization, margin testing, and long-duration stability and reliability\nDrive validation through each NPI phase (Proto, EVT, DVT, PVT, and production) and define entry and exit criteria for each\nDebug and root-cause issues across silicon, board, firmware (BIOS/UEFI, BMC, device firmware), OS and drivers, networking, power, and thermal\nDrive the NPI and production ramp: define L6, L10, and L11 test content and acceptance criteria with ODM and CM partners, improve factory test yield, and support data center bring-up, field deployment, field failure analysis, and RMA\nPartner with silicon validation, board and system hardware, thermal, firmware, software, networking, manufacturing and test engineering, ODM and CM partners, suppliers, and data center operations\nWhat We're Looking For\n5+ years of experience in system validation, system integration, or bring-up for servers, accelerators, or rack-scale systems\nStrong coding skills in Python, C, and C++, plus solid Linux systems experience\nExperience with BMC (OpenBMC), Redfish, and IPMI\nProven system and rack bring-up experience, from first power-on through full validation\nExperience validating hardware through NPI phases (Proto, EVT, DVT, PVT) and into production\nExperience working with ODM and CM partners on L6/L10/L11 test content, acceptance criteria, and factory yield\nStrong debug skills and fluency with tools such as PCIe and Ethernet protocol analyzers, oscilloscopes, logic analyzers, JTAG debuggers, and BMC logs and telemetry\nExperience building test automation, telemetry, and triage infrastructure at fleet scale\nDeep expertise in one or more of the following:AI training and inference workloads and collectives at scale\nPCIe Gen5/6/7, CXL, PCIe switches, and retimers\nScale-up fabrics and switches\n112G/224G SerDes, copper cables and backplanes, and optics\nScale-out networking, RDMA, and RoCE\nRack power delivery and power management\nLiquid cooling and thermal\nSystem management and firmware update\nRAS and error handling\nSecure boot\nSystem performance\n\nStrong collaboration and communication skills across internal teams, manufacturing partners, and data center operations\nFull compensation packages are based on candidate experience and relevant certifications. \nCalifornia pay range\n$250,000—$300,000 USD\nCompensation\nFinal offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO. \nVisa Sponsorship\nDensityAI sponsors qualified candidates for H-1B, O-1, TN, E-3, and other employment-based visas, and we welcome applicants on F-1 OPT and STEM-OPT. Work authorization is required at start; we provide immigration support to secure or transfer status.\nExport Controls\nAspects of this role may involve access to information subject to U.S. export controls (EAR/ITAR). We may discuss licensing or scope adjustments during the interview.\nEqual Opportunity\nDensityAI is an Equal Opportunity Employer.
