Signal Integrity Engineer - Serdes, Satellites (Starlink)

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.SIGNAL INTEGRITY 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 Integrity Engineer on Starlink’s Payload Engineering team, you’ll have SI 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, stack-up material selection and characterization, channel 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. You will help 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 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 optoelectronicsHigh-speed and high-bandwidth memory interfaces (DDR4, LPDDR5, GPDDR6, QSPI NOR, eMMC, etc.)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 strategiesDerive top level specifications for PCB materials and channel subcomponentsDesign and optimize transition structures for the entire channel from die bump to die bumpRoot cause and fix issues found in PCB manufacturing, PCBA test, or satellite integrationDefine best practices, simulation workflows, test methodologies, signoff criteria, and lab equipment needs for all SI needs on Starlink satellite payloadsBASIC QUALIFICATIONS:Bachelor’s degree in electrical engineering, computer engineering, or physics1+ years of industry experience designing circuits, electronic products, or hardware (internships, co-ops, and research/lab work can apply)1+ years of experience using one of the 3D EM simulation tools and high-speed digital channel simulators (CST, HFSS, ADS etc.)1+ years of research or industry experience with high-speed digital design PREFERRED SKILLS AND EXPERIENCE: Master’s degree or PhD in electrical engineering, computer engineering with emphasis in electromagnetic theory, transmission line theory, or wireline transceivers3+ 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 hardware3+ years of experience architecting, implementing, and debugging cutting edge DSP based SERDES products (i.e. 56Gbps, 112Gbps, 224Gbps) working across package and PCB3+ years of experience specifying, analyzing, debugging, and working with high speed, high bandwidth memory interfacesThorough understanding of wireline transceiver concepts, architectures, and circuitsStrong understanding of computers and programming languages (Python, C/C++)Demonstrated ability to work in a highly cross-functional roleExperience with low loss laminates, high volume PCB manufacturing, and high-speed connectorsExperience debugging and resolving EMI/EMC de-sense problemsPassion for working in dynamic cross-functional role to optimize package, PCB, ASIC, mixed signal circuit to deliver best in class productsADDITIONAL REQUIREMENTS: Ability to work extended hours or weekends as needed for mission critical deadlinesSome travel may occasionally be requiredCOMPENSATION AND BENEFITS: Pay Range: Level 1: $105,000.00 - $145,000.00Level 2: $120,000.00 - $175,000.00Your 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 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 and long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year. Employees in Washington State accrue paid sick time in compliance with state and federal law. Company shuttles are offered to employees for roundtrip travel from select Seattle locations to the SpaceX Redmond office Monday to Friday.ITAR REQUIREMENTS:To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
