Platform Firmware Engineer, AI Datacenter

What To Expect

Tesla's AI Hardware team builds the custom silicon and datacenter infrastructure behind Full Self-Driving, Optimus, and some of the largest AI training clusters in the world. Every GPU, every custom accelerator, and every server in these clusters depends on PCIe as the critical high-speed interconnect linking compute, memory, networking, and storage. As we push toward PCIe Gen 5 and Gen 6 speeds, the firmware and driver stack must deliver maximum bandwidth, minimal latency, and rock-solid reliability at massive scale.

• Develop and optimise PCIe Gen 5/Gen 6 firmware and Linux kernel drivers for Tesla's AI compute platforms
• Implement PCIe enumeration, link training, and configuration for custom SoCs and accelerator cards
• Bring up prototype hardware and develop proof-of-concept firmware to validate new platform designs before production
• Build and run platform-level validation—PCIe performance, thermal, power, and stress testing across the full compute stack under AI training workloads
• Debug PCIe link failures, signal integrity issues, and protocol errors using analyzers and silicon debug tools
• Develop Linux device drivers for custom hardware—DMA, interrupts, MMIO, and peer-to-peer transfers
• Drive root cause analysis of PCIe failures across firmware, kernel, and hardware

• Degree in Computer Engineering, Electrical Engineering, Computer Science, or equivalent experience
• 8+ years in firmware or low-level software development
• Expertise in PCIe Gen4/5/6 architecture, platform validation and performance testing, and high-speed networking stacks that share PCIe infrastructure
• Linux kernel driver development (device drivers, DMA, interrupts) and image build using Yocto or Buildroot
• C programming; kernel debug tools (ftrace, perf, crash)
• Hardware debug experience—protocol analyzers, JTAG, oscilloscopes
• System architecture fundamentals—IOMMU, NUMA, memory hierarchies
• Background in AI/ML infrastructure and familiarity with large-scale AI workload characteristics and their impact on interconnect performance
• Familiarity with GPU/accelerator interconnects such as CXL, NVLink, Infinity Fabric, UALink, or similar chip-to-chip and multi-node interconnect technologies

• Medical plans > plan options with $0 payroll deduction
• Family-building, fertility, adoption and surrogacy benefits
• Dental (including orthodontic coverage) and vision plans, both have options with a $0 paycheck contribution
• Company Paid (Health Savings Accounts) HSA Contribution when enrolled in the High-Deductible medical plan with HSA
• Healthcare and Dependent Care Flexible Spending Accounts (FSA)
• 401(k) with employer match, Employee Stock Purchase Plans, and other financial benefits
• Company paid Basic Life, AD&D
• Short-term and long-term disability insurance (90 day waiting period)
• Employee Assistance Program
• Sick and Vacation time (Flex time for salary positions, Accrued hours for Hourly positions), and Paid Holidays
• Back-up childcare and parenting support resources
• Voluntary benefits to include: critical illness, hospital indemnity, accident insurance, theft & legal services, and pet insurance
• Weight Loss and Tobacco Cessation Programs
• Tesla Babies program
• Commuter benefits
• Employee discounts and perks program

$188,000 - $432,000/annual salary + cash and stock awards + benefits
