Systems Integration & Validation Engineer

DensityAI • Mountain View, CA

1d • $250,000 - $300,000

About The Position

Own end-to-end validation of AI rack-scale systems, from board and tray bring-up through full racks and multi-rack clusters, including L11 rack integration and field deployment. The systems include accelerator compute trays, host servers, scale-up switches, and related components such as NICs, retimers, cables, power shelves, busbars, liquid cooling, and rack management. Build the plans, environments, and automation needed to demonstrate system operation at fleet scale, collaborating with silicon, hardware, firmware, software, manufacturing, ODM, and CM teams.

Requirements

• 5+ years of experience in system validation, system integration, or bring-up for servers, accelerators, or rack-scale systems.
• Strong coding skills in Python, C, and C++, and solid Linux systems experience.
• Experience with BMC (OpenBMC), Redfish, and IPMI.
• Proven system and rack bring-up experience, from first power-on through full validation.
• Experience validating hardware through NPI phases (Proto, EVT, DVT, PVT) and into production.
• Experience working with ODM and CM partners on L6/L10/L11 test content, acceptance criteria, and factory yield.
• Strong debugging skills and fluency with tools such as PCIe and Ethernet protocol analyzers, oscilloscopes, logic analyzers, JTAG debuggers, and BMC logs and telemetry.
• Experience building test automation, telemetry, and triage infrastructure at fleet scale.
• Strong collaboration and communication skills across internal teams, manufacturing partners, and data center operations.

Nice To Haves

• Deep expertise in one or more of the following: AI training and inference workloads and collectives at scale; PCIe Gen5/6/7, CXL, PCIe switches, and retimers; scale-up fabrics and switches; 112G/224G SerDes, copper cables and backplanes, and optics; scale-out networking, RDMA, and RoCE; rack power delivery and power management; liquid cooling and thermal; system management and firmware update; RAS and error handling; secure boot; or system performance.
• Relevant certifications (considered in determining compensation).

Responsibilities

• Create system validation plans for AI rack-scale systems at board, tray, rack, and multi-rack cluster levels through L11 rack integration.
• Build validation environments including system diagnostics, stress and burn-in tests, workload-based tests, fleet health checks, and rack acceptance tests.
• Develop test automation that scales execution and automated triage across hundreds of racks and thousands of trays, including telemetry collection, results databases, and dashboards.
• Lead system and rack bring-up from first power-on through full validation, including interoperability, power, thermal and performance characterization, margin testing, and long-duration stability and reliability.
• Drive validation through NPI phases (Proto, EVT, DVT, PVT, and production) and define entry and exit criteria for each phase.
• Debug and root-cause issues across silicon, boards, firmware, operating systems and drivers, networking, power, and thermal systems.
• Drive NPI and production ramp by defining L6, L10, and L11 test content and acceptance criteria with ODM and CM partners, improving factory test yield, and supporting data center bring-up, field deployment, field failure analysis, and RMA.
• Partner with silicon validation, hardware, thermal, firmware, software, networking, manufacturing and test engineering, ODM and CM partners, suppliers, and data center operations.

Benefits

• Equity grant per company guidelines.
• Medical, dental, and vision benefits.
• 401(k).
• Standard PTO.
• Immigration support for qualified candidates seeking to secure or transfer employment-based visa status.
