Memory Design Interface Architect

Category Terafab
Location Austin, Texas
Requisition ID 287517
Type Full-time

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>

Job Responsibilities

  • Own HBM IO blocks and subsystems from architecture through circuit and RTL implementation, verification, tape-out, bring-up, and post-silicon debug
  • Set the 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 the bandwidth, latency, power, area, reliability, signal integrity, power integrity, yield, and manufacturability trade-offs, and hold the line on them
  • Design the analog, mixed-signal, and digital interface functions inside the high-speed memory subsystem
  • Work with package, interposer, physical design, signal integrity, power integrity, and thermal to close the interface across 2.5D and 3D assemblies
  • Lead root-cause on the hard bugs: circuit, RTL, architecture, process, package, interposer, and system, pre-silicon and post-silicon
  • Run one or more interface programs. Set the spec, the plan, the risks, and the schedule, and keep architecture, design, layout, verification, validation, packaging, test, and product engineering on that plan
  • Work with internal teams, IP providers, foundries, and partners to integrate high-speed memory and die-to-die interfaces
  • Push the next HBM, chiplet, and heterogeneous-integration architectures against Tesla’s training and inference workloads
  • Mentor engineers in architecture reviews, build reviews, and debug. Tighten the methods, the guidelines, and what we reuse

Job Requirements

  • 15+ years in HBM, DDR, LPDDR, high-speed PHY, mixed-signal, SoC, or ASIC design, or equivalent experience
  • 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. HBM product families preferred
  • Analog and mixed-signal circuit design, digital microarchitecture, RTL, clocking, training, calibration, power management, and error handling
  • Front-end implementation and verification: synthesis, static timing, logic equivalence, and RTL debug
  • Experience leading technical execution across disciplines and sites
  • Working knowledge of DRAM operation, HBM and DDR, JEDEC, and memory subsystems

Common Interview Questions And Answers

1. HOW DO YOU PLAN YOUR DAY?

This is what this question poses: When do you focus and start working seriously? What are the hours you work optimally? Are you a night owl? A morning bird? Remote teams can be made up of people working on different shifts and around the world, so you won't necessarily be stuck in the 9-5 schedule if it's not for you...

2. HOW DO YOU USE THE DIFFERENT COMMUNICATION TOOLS IN DIFFERENT SITUATIONS?

When you're working on a remote team, there's no way to chat in the hallway between meetings or catch up on the latest project during an office carpool. Therefore, virtual communication will be absolutely essential to get your work done...

3. WHAT IS "WORKING REMOTE" REALLY FOR YOU?

Many people want to work remotely because of the flexibility it allows. You can work anywhere and at any time of the day...

4. WHAT DO YOU NEED IN YOUR PHYSICAL WORKSPACE TO SUCCEED IN YOUR WORK?

With this question, companies are looking to see what equipment they may need to provide you with and to verify how aware you are of what remote working could mean for you physically and logistically...

5. HOW DO YOU PROCESS INFORMATION?

Several years ago, I was working in a team to plan a big event. My supervisor made us all work as a team before the big day. One of our activities has been to find out how each of us processes information...

6. HOW DO YOU MANAGE THE CALENDAR AND THE PROGRAM? WHICH APPLICATIONS / SYSTEM DO YOU USE?

Or you may receive even more specific questions, such as: What's on your calendar? Do you plan blocks of time to do certain types of work? Do you have an open calendar that everyone can see?...

7. HOW DO YOU ORGANIZE FILES, LINKS, AND TABS ON YOUR COMPUTER?

Just like your schedule, how you track files and other information is very important. After all, everything is digital!...

8. HOW TO PRIORITIZE WORK?

The day I watched Marie Forleo's film separating the important from the urgent, my life changed. Not all remote jobs start fast, but most of them are...

9. HOW DO YOU PREPARE FOR A MEETING AND PREPARE A MEETING? WHAT DO YOU SEE HAPPENING DURING THE MEETING?

Just as communication is essential when working remotely, so is organization. Because you won't have those opportunities in the elevator or a casual conversation in the lunchroom, you should take advantage of the little time you have in a video or phone conference...

10. HOW DO YOU USE TECHNOLOGY ON A DAILY BASIS, IN YOUR WORK AND FOR YOUR PLEASURE?

This is a great question because it shows your comfort level with technology, which is very important for a remote worker because you will be working with technology over time...
