SerDes Characterization and Validation Engineer (Silicon Engineering)

SpaceX

SpaceX

Irvine, CA, USA
Posted on Tuesday, July 18, 2023

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

SERDES CHARACTERIZATION AND VALIDATION ENGINEER (SILICON ENGINEERING)

At SpaceX we’re leveraging our 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 1.5M+ 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 and are looking for best-in-class engineers to help maximize Starlink’s utility for communities and businesses around the globe.

We are seeking a motivated, proactive, and intellectually curious engineer who will work alongside world-class cross-disciplinary teams (systems, firmware, architecture, design, validation, product engineering, ASIC implementation). In this role, you will be developing cutting-edge next-generation ASICs for deployment in space and ground infrastructures around the globe. These chips are enabling connectivity in places it has previously not been available, affordable or reliable. Your efforts will help deliver cutting-edge solutions that will expand the performance and capabilities of the Starlink network.

RESPONSIBILITIES:

  • Bring up, validate and characterize high speed SerDes blocks in new and existing silicon chips
  • Develop test methods to evaluate performance and calculate operating margins of high-speed serial interfaces (SerDes) across PVT and additional environmental conditions specific to space applications
  • Work closely with the ASIC design team to add/improve testability and define various loopback and test infrastructure logic to ensure adequate silicon test coverage
  • Work closely with electrical design team to review signal integrity, power integrity and radiated/conducted emissions concerns as well as propose design changes or operational workarounds
  • Evaluate new SerDes IP from internal and external IP providers and test for logical and electrical compatibility with existing chips and FPGAs
  • Write software routines (Python, C/C++) to bring up and validate the SerDes while working with the software cross functional team members to help integrate SerDes drivers in the software track

BASIC QUALIFICATIONS:

  • Bachelor’s degree in electrical engineering, computer engineering or computer science
  • 3+ years of experience working on SerDes platforms

PREFERRED SKILLS AND EXPERIENCE:

  • Experience working with various high speed SerDes architectures (NRZ, PAM4) and protocols
  • Working knowledge of Serdes block, e.g. CTLE, DFE, FFE, CDR and PLLs, their characterization and debug.
  • Very good working knowledge of test and measurement equipment such as high-speed Oscillators, BERTs
  • Understanding of SerDes calibration, including how equalization parameters are chosen
  • Working knowledge of SerDes Signal Integrity eye diagrams, Bathtub Curves, etc
  • Working experience with ethernet, PCIe and other high-speed protocol layers is a definite plus
  • Ability to study and analyze internal and external resources to lead SerDes IP selections and discussions
  • Experience writing comprehensive test reports covering test boundary conditions and test results
  • Strong debugging and problem-solving skills

COMPENSATION AND BENEFITS:

Pay range:
ASIC/FPGA Engineer/Level I: $120,000.00 - $145,000.00/per year
ASIC/FPGA Engineer/Level II: $140,000.00 - $170,000.00/per year

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.

Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation & will be eligible for 10 or more paid holidays per year. Exempt employees are eligible for 5 days of sick leave per year.
