About the Job

Requirements

At least 15 years of experience in HBM, DDR, LPDDR, high-speed PHY, mixed-signal, SoC, or ASIC design, or equivalent experience.
A degree in Electrical Engineering, Computer Engineering, or a related field, or equivalent experience.
Experience taking complex interface IP or a subsystem from architecture through silicon bring-up and post-silicon debug.
Deep experience in high-speed memory-interface architecture and design.
Experience in analog and mixed-signal circuit design, digital microarchitecture, RTL, clocking, training, calibration, power management, and error handling.
Experience with front-end implementation and verification, including synthesis, static timing, logic equivalence, and RTL debugging.
Experience leading technical execution across disciplines and sites.
Working knowledge of DRAM operation, HBM and DDR, JEDEC, and memory subsystems.

Responsibilities

Own HBM IO blocks and subsystems from architecture through circuit and RTL implementation, verification, tape-out, bring-up, and post-silicon debugging.
Set requirements for the HBM PHY, controller-to-PHY, die-to-die links, clocking, training, calibration, power management, error handling, and test, including support for future interface technologies.
Make bandwidth, latency, power, area, reliability, signal-integrity, power-integrity, yield, and manufacturability trade-offs and uphold them.
Design analog, mixed-signal, and digital interface functions within the high-speed memory subsystem.
Work with package, interposer, physical design, signal-integrity, power-integrity, and thermal teams to close the interface across 2.5D and 3D assemblies.
Lead root-cause analysis of circuit, RTL, architecture, process, package, interposer, and system bugs, both pre-silicon and post-silicon.
Run one or more interface programs; set the specification, plan, risks, and schedule, and keep architecture, design, layout, verification, validation, packaging, test, and product engineering aligned to the plan.
Work with internal teams, IP providers, foundries, and partners to integrate high-speed memory and die-to-die interfaces.
Advance HBM, chiplet, and heterogeneous-integration architectures for Tesla’s training and inference workloads.
Mentor engineers in architecture reviews, build reviews, and debugging; improve methods and guidelines and determine what to reuse.

Desired Qualifications

Experience with HBM product families is preferred.

Job Description

<p>We are building Terafab, a vertically integrated semiconductor factory at an unprecedented scale. The facility houses logic, memory, packaging, test, and lithography mask production under one roof, optimized for rapid iteration and maximum compute density per square foot. </p><p>In this role, you will own HBM IO blocks and the subsystems around them from spec to tape-out to bring-up. That includes the PHY, controller-to-PHY, die-to-die, clocking, training, and electrical interfaces that support future interfaces. The work collaborates closely with the AI Hardware team, the people who define the workloads and the people who package the die. </p>

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
