Hardware Test Engineer – AI Accelerator (Equity)

DensityAI; Mountain View (WY); On-site; USD 230,000 - 290,000; Full time

Job summary

DensityAI is seeking an experienced hardware test engineer to own test strategies across package, board, and system levels. You will develop test setups, fixtures, and AI-assisted flows to drive yield, coverage, and throughput for accelerator hardware.

You will collaborate with design, packaging, and reliability teams to define specs and drive ramp to high volume, with options for equity and a comprehensive benefits package.

Qualifications

• BS/MS in Electrical/Computer Engineering or equivalent.
• 5+ years in package/board/system-level hardware test engineering.
• Hands-on test experience across at least two of package-level, board-level, and system-level test.
• Package and board test hardware experience (sockets, connectors, load boards, fixtures) and SI/PI awareness.
• Lab bring-up and debug skills: oscilloscopes, logic and protocol analyzers, power and thermal instrumentation.
• Data analysis and statistics for yield, characterization, and correlation.
• Optional: High-speed I/O/SerDes, DDR/HBM, RF; scripting/automation (Python, C++); OSAT/CM partner management.

Responsibilities

• Develop and run package-level test- socket-based bring-up and validation of packaged units: power-up, interface/interconnect continuity, and functional/parametric checks against spec.
• Develop and run board-level test- functional, structural (boundary scan/JTAG), in-circuit, and bring-up validation for accelerator boards and system hardware.
• Build out system-level test- bring up and validate assembled accelerator systems against spec, including functional, stress, and burn-in flows.
• Design and validate test hardware and fixtures- sockets, connectors, load boards, and board/system fixtures for high-speed and high-current test.
• Drive test coverage, yield analysis, and test-time/cost reduction across the product lifecycle.
• Lead new-product test bring-up; resolve test escapes, yield excursions, and hardware failures with data-driven root cause.
• Run characterization and correlation across levels- package-board-system, and bench-production test.
• Define test specs, limits, and guardbands with design, product, packaging, and reliability engineering.
• Transfer and sustain test programs at OSAT/CM and manufacturing partners through ramp to high volume.
• Use and develop AI-assisted tool flows to accelerate test development, debug, and yield analysis.
