Job Description

OverviewSpaceX 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.SR. HIGH-SPEED ELECTRO-OPTICAL IC ENGINEER (SILICON ENGINEERING)At SpaceX were leveraging our experience in building rockets and spacecraft to deploy Starlink, the worlds most advanced broadband internet system. Starlink is the worlds 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. Weve only begun to scratch the surface of Starlinks potential global impact and are looking for best-in-class engineers to help maximize Starlinks utility for communities and businesses around the globe.We are seeking a motivated, proactive, and intellectually curious Electrical-optical Silicon photonics IC engineer who will work alongside world-class cross-disciplinary teams (systems, firmware, architecture, design, validation, product engineering). In this role, you will be developing cutting-edge next-generation PIC/EIC for deployment in space and ground infrastructures around the globe. These chips are enabling connectivity in places it has not previously been available, affordable or reliable. Join us to help deliver cutting-edge solutions that will expand the performance and capabilities of the Starlink network.ResponsibilitiesDesign, simulate and model electro-optical building blocks for a silicon photonics solutionDesign, simulate and model RF/analog/mixed signal circuits and systemsDerive specifications for the Photonics IC/Electrical IC subsystems and circuitsDevelop Analog/Mixed-Signal/RF/Microwave circuits in SiGe or CMOS processesWork with system architects, DSP and electro-optics, and ASIC engineers to partition functions between hardware and software domainsPerform IC floor planning and layoutModel package and external parasitic componentsEvaluate, characterize and measure electrical and optical building blocks of a high-speed optical link solutionAssist in the development of automated test lab equipment for lab measurementsWork with manufacturing engineers on production testing and qualification of the EIC/PIC components and systemsBasic QualificationsBachelor''s degree in electrical engineering, computer engineering, or computer science5+ years of photonics or electro-optical integrated circuit designPreferred Skills and ExperienceMaster''s degree or PhD in electrical engineering or computer engineering with an emphasis in electro-optics integrated circuit designExperience using simulation tools such as Spectre, ADS, HFSS or Momentum, Ansys Lumerical, COMSOLPhotonics design skills, and experience performing analysis and simulation of optical building blocks such as MZM and Microring modulators, Ge Photo diodes, dWDM filters, waveguides, couplers, dividers and polarization management circuitryElectrical circuit design skills, and experience performing analysis and simulation of both linear and non-linear circuits such as high bandwidth modulator drivers, TIAs, CTLEs, filters, low noise and power amplifiersKnowledge of advanced packaging technology for optical engine integration in a co-package optics (CPO) solutionExperience working on wideband circuit designs supporting high speed Serdes links with more than 100Gbps data rate and BW exceeding 10s of GHzFamiliarity with high speed SerDes architecture, modulation schemes such as NRZ and PAM4 and link protocolsFamiliarity with optical and radio related test equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, high speed oscilloscopes and BERTsExperience characterizing EIC/PIC performance for high speed optical SerdesAdditional RequirementsAbility to work long hours and weekends as necessary to support critical milestonesCompensation and BenefitsPay range: RFIC Engineer/Senior: $160,000.00 - $220,000/per yearYour 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.
