What are the key skills and qualifications needed to thrive as a High Bandwidth Memory (HBM) Engineer, and why are they important?

To thrive as a High Bandwidth Memory (HBM) Engineer, you need a solid background in electrical engineering or computer engineering, with expertise in memory architectures and semiconductor design. Familiarity with tools such as Verilog/VHDL, circuit simulation software, and experience with DRAM or HBM standards are typically required, along with relevant certifications in hardware design. Strong problem-solving skills, attention to detail, and effective teamwork distinguish top performers in this field. These skills are essential to ensure the development of reliable, high-performance memory solutions critical for advanced computing systems.

What are some typical challenges faced by engineers working with High Bandwidth Memory (HBM) technologies?

Engineers working with High Bandwidth Memory often encounter challenges such as managing thermal constraints due to HBM’s high data throughput and stacked architecture. Integrating HBM with processors or FPGAs requires precise PCB design and signal integrity considerations to ensure reliable performance. Additionally, staying updated on evolving HBM standards and collaborating closely with cross-functional teams—such as hardware, firmware, and product design—is essential for successful implementation. These challenges make adaptability and strong communication skills valuable in this role.

What is High Bandwidth Memory (HBM)?

High Bandwidth Memory (HBM) is a type of high-speed computer memory used primarily in graphics cards, high-performance computing, and advanced AI processors. Unlike traditional memory, HBM stacks memory chips vertically and connects them with wide data buses, allowing for much higher data transfer rates and lower power consumption. This architecture enables faster performance and greater efficiency, making it ideal for demanding workloads. HBM is commonly used in GPUs, FPGAs, and data center applications where speed and bandwidth are critical.

What is the difference between High Bandwidth Memory vs GPU Architect?

AspectHigh Bandwidth MemoryGPU Architect
Primary FocusMemory technology design and optimizationGPU architecture and performance design
Required CredentialsElectrical engineering, computer engineeringComputer engineering, hardware design
Work EnvironmentMemory chip manufacturing, hardware R&DGPU design labs, hardware development
Industry UsageSemiconductor companies, memory manufacturers

High Bandwidth Memory specialists focus on developing and optimizing memory technologies, while GPU Architects design the overall architecture of graphics processing units. Both roles require strong technical credentials and often collaborate within hardware development teams, but they concentrate on different components of computing systems.

Job description

SR. SI/PI ENGINEER - SERDES, SATELLITES (STARLINK)

SpaceX is leveraging its experience in building rockets and spacecraft to deploy Starlink, the world's most advanced broadband internet system. Starlink is the world's largest satellite constellation and is providing fast, reliable internet to millions of users worldwide. We design, build, test, and operate all parts of the system - thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We've only begun to scratch the surface of Starlink's potential global impact. As we continue to upgrade and expand the constellation, we're looking for best-in-class engineers to join the team. 

As a Signal and Power Integrity Engineer on Starlink's Payload Engineering team, you'll have SI and PI ownership throughout the entire life-cycle of the portfolio of hardware that enables this connectivity, and sits at the intersection of electrical, mechanical, thermal analysis, software, and antenna/RF engineering. Early in any given product's design cycle, your work will include everything from IP evaluation in the silicon architecture stage, package performance evaluation, stackup material selection and characterization, channel and PDN architecture, and PCB layout oversight. Once hardware is in hand, you will drive troubleshooting, characterization, qualification, and general debug across all phases of the product's life.  

As a subject matter expert on SI and PI, you will define the design, analysis, and verification processes and tools that the Starlink team uses when developing hardware. You will have wide latitude to determine how best to tackle these problems and be expected to spread the associated knowledge and techniques to engineers across the Starlink program. 

RESPONSIBILITIES

  • Specify, design, simulate, verify, qualify, define production screens for, and generally troubleshoot SI and PI aspects of advanced satellite hardware, such as:
    • Wireline and electro-optical communication systems with cutting edge (e.g. 10 to 112+ Gbps) SERDES, DSPs, retimers, and optoelectronics
    • High-speed and high-bandwidth memory interfaces (DDR4, LPDDR5, GPDDR6, QSPI NOR, eMMC, etc.)
    • Power needs and PDNs for the associated ASICs
  • Work alongside RF engineers, antenna engineers, ASIC engineers, packaging engineers, mechanical engineers, thermal engineers, software engineers, supply chain, and production engineers (among others) to architect new products which will employ novel channels, interfaces, and power delivery strategies
  • Derive top level specifications for PCB materials and channel subcomponents
  • Design and optimize transition structures for the entire channel from die bump to die bump
  • Drive detailed component selection to accompany your PDN designs
  • Root cause and fix issues found in PCB manufacturing, PCBA test, or satellite integration
  • Define best practices, simulation workflows, test methodologies, signoff criteria, and lab equipment needs for all SI/PI needs on Starlink satellite payloads

BASIC QUALIFICATIONS: 

  • Bachelor's degree in electrical engineering, computer engineering, or physics
  • 5+ years of industry experience designing circuits, electronic products, or hardware
  • 2+ years of experience using one of the 3D EM simulation tools and high-speed digital channel simulators (CST, HFSS, ADS etc.)
  • 2+ yearsof research or industry experience with high-speed digital design or power integrity

PREFERRED SKILLS AND EXPERIENCE: 

  • Master's degree or PhD in electrical engineering, computer engineering with emphasis in electromagnetic theory, transmission line theory, wireline transceivers, or power integrity
  • 5+ years of electronic product experience designing hardware from concept through production; strong emphasis on full life-cycle development of new hardware products and not small incremental updates to legacy hardware
  • 5+ years of experience architecting, implementing, and debugging cutting edge DSP based SERDES products (i.e. 56Gbps, 112Gbps, 224Gbps) working across package and PCB
  • 5+ years of experience specifying, analyzing, debugging, and working with high speed, high bandwidth memory interfaces
  • 5+ years of experience designing, implementing, and debugging power delivery networks for large processors, FPGAs, SoC, or ASICs with complex power requirements
  • Thorough understanding of wireline transceiver concepts, architectures, and circuits
  • Strong understanding of computers and programming languages (Python, C/C++)
  • Demonstrated ability to work in a highly cross-functional role
  • Experience with low loss laminates, high volume PCB manufacturing, and high-speed connectors
  • Experience debugging and resolving EMI/EMC de-sense problems
  • Passion for working in dynamic cross-functional role to optimize package, PCB, ASIC, mixed signal circuit to deliver best in class products

ADDITIONAL REQUIREMENTS: 

  • Ability to work extended hours or weekends as needed for mission critical deadlines
  • Some travel may occasionally be required

COMPENSATION AND BENEFITS: 

Pay range: 
Signal & Power Integrity Engineer/Senior: $140,000 - $190,000/per year
