Staff Electrical Engineer, SI Hardware

The Tesla SI Hardware team is at the forefront of revolutionizing artificial intelligence through cutting-edge hardware innovation. Comprising brilliant engineers and visionaries, the team designs and develops advanced SI inference chips tailored to accelerate Tesla’s machine learning capabilities. A key part of this effort is Dojo, Tesla's custom supercomputer system built to efficiently train massive neural networks on vast video data from the fleet. The work of Tesla's SI Hardware team powers the neural networks behind Full Self-Driving (FSD), and Tesla humanoid robot, Optimus, pushing the boundaries of computational efficiency and performance. By creating custom silicon and optimized architectures, the team ensures Tesla remains a leader in SI-driven automotive and energy solutions, shaping a future where intelligent machines enhance human life.

Dojo3 is Tesla’s next-generation AI data center program. We are seeking a Staff or Senior Staff Electrical Engineer to lead the electrical architecture and design of the Dojo3 system across the full rack: compute trays (motherboard, x86 host CPU, NIC), switch trays, the top-of-rack (ToR) switch, the power delivery busbar, power delivery boards (PDB), and control boards. This is a hands-on technical leadership role at the leading edge of 448 Gbps SerDes, PCIe Gen7, and scale-up and scale-out fabrics, taking the rack from a blank sheet to high-volume production.

- Define the electrical architecture of the Dojo3 system, including compute trays, switch trays, the ToR switch, the power delivery busbar, and rack management, and own the rack and tray power budgets
- Define the rack power architecture from power shelves through the busbar and PDBs to point-of-load regulators, including busbar sizing, hot-swap/eFuse protection, and multiphase VR design
- Own schematic design for compute tray, switch tray, PDB, and control boards; work with layout designers through layout sign-off, and perform DC power analysis of power planes
- Design 448 Gbps SerDes and PCIe Gen7/Gen6 channels across trays, switches, connectors, and cables for scale-up and scale-out links, working with SI engineers
- Validate power supplies for efficiency, time- and frequency-domain performance, loop stability, and transient response
- Lead electrical bring-up from first boards through full-rack integration, run electrical validation across PVT corners, and publish hardware test reports
- Define hardware-facing firmware and configuration with the firmware team: microcontroller firmware, CPLD power sequencing, switch and retimer configuration, and VR programming
- Serve as the electrical technical lead: set design direction, run design reviews, mentor engineers, and work with silicon, mechanical, thermal, firmware, manufacturing, and ODM/JDM partners through mass production

- Degree in Electrical or Computer Engineering, or equivalent experience
- 7+ years (Staff) or 10+ years (Sr. Staff) of hands-on hardware design experience on server, networking, or AI compute systems, with end-to-end ownership from architecture through mass production
- Rack-level system design experience, and x86 server motherboard design experience (Intel Xeon / AMD EPYC)
- High-speed board design with 112G+ PAM4 SerDes and PCIe Gen5/Gen6, including stackup definition, low-loss material selection, and connector and cable channel design
- Strong power delivery fundamentals from rack to point of load (busbars, hot-swap/eFuse, intermediate bus converters, multiphase VRs, PDN, DC IR drop), and hands-on power supply validation
- Skilled with lab equipment (oscilloscopes, power analyzers, electronic loads, frequency response analyzers) and Cadence or Altium design tools
- Proven technical leadership and communication skills: led complex designs through multiple product generations, mentored engineers, and thrived in fast-paced environments with evolving requirements
- Experience with 224G/448G SerDes, COM/ERL channel analysis, PCIe Gen7/CXL, and co-packaged or linear-drive optics is a plus
- Experience with high-radix switch ASIC boards (51.2T/102.4T-class), scale-up or scale-out networking (UALink, 800G/1.6T Ethernet), or rack power (OCP ORv3 48V busbars, high-voltage DC distribution, battery backup units) is a plus
