Hardware Bring-Up Engineer

You will take the first silicon from power-on to a working system — the first to touch new boards, the one who decides what is actually broken, and the person the whole hardware team depends on during the weeks that matter most. Hands-on lab role with wide cross-functional reach.

What you will work on:

• First power-on and bring-up of a multi-die AI accelerator board
• Debug and triage across power, clocks, reset, boot, high-speed interfaces and firmware
• Lab infrastructure: test benches, instrumentation, fixtures and automation
• Characterisation and margin testing on real silicon
• Rack-scale system integration and multi-node bring-up

Responsibilities:

• Bring-up execution: Own the power-on sequence, voltage and clock checks, reset and boot flow, and the first interface links to train. Write and maintain the bring-up checklist and run it on every new build.
• Debug & triage: Isolate failures across hardware, firmware and software, and route them to the right owner with evidence. Use scopes, logic analysers, protocol analysers, JTAG and on-die telemetry to localise root cause.
• Lab ownership: Build and maintain test setups, fixtures and instrumentation. Automate repetitive measurement and data collection so results are reproducible across boards and builds.
• Characterisation: Run margin, shmoo and corner testing on power rails, clocks and high-speed interfaces. Feed measured data back to SI, PI, power and design teams.
• Cross-functional: Work closely with design, firmware, validation and manufacturing. Support board respins with clear failure analysis, and hand off stable platforms to validation and production test.

Requirements:

• 5+ years bringing up complex digital boards — server, networking, ASIC/FPGA platforms or comparable
• Proven first-silicon or first-board bring-up experience, start to working system
• Strong lab skills: oscilloscopes, logic and protocol analysers, power measurement, JTAG and debug interfaces
• Able to read schematics, layout and datasheets, and reason about what the board should be doing
• Experience debugging across the hardware/firmware boundary, including boot and sequencing issues
• Python scripting for test automation, instrument control and data analysis

Nice to Have:

• High-speed interface bring-up: PCIe, DDR/LPDDR, Ethernet or SerDes link training and margining
• BMC, firmware or embedded Linux familiarity
• Experience with rack-scale or multi-node system integration
• Rework and board-level repair skills
• Exposure to automated or AI-assisted lab and test flows
