Sr. High-Speed Electro-Optical IC Engineer (RFIC Engineering)

SpaceX · Redmond, WA · Mar 10, 2026

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. SR. HIGH-SPEED ELECTRO-OPTICAL IC ENGINEER (RFIC 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 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 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 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.

Responsibilities:

• Design, simulate and model electro-optical building blocks for a silicon photonics solution

• Design, simulate and model RF/analog/mixed signal circuits and systems

• Derive specifications for the Photonics IC/Electrical IC subsystems and circuits

• Develop Analog/Mixed-Signal/RF/Microwave circuits in SiGe or CMOS processes

• Work with system architects, DSP and electro-optics, and ASIC engineers to partition functions between hardware and software domains

• Perform IC floor planning and layout

• Model package and external parasitic components

• Evaluate, characterize and measure electrical and optical building blocks of a high-speed optical link solution

• Assist in the development of automated test lab equipment for lab measurements

• Work with manufacturing engineers on production testing and qualification of the EIC/PIC components and systems

Requirements:

• Bachelor's degree in electrical engineering, computer engineering, or computer science

• 5+ years of photonics or electro-optical integrated circuit design

• Master's degree or PhD in electrical engineering or computer engineering with an emphasis in electro-optics integrated circuit design

• Experience using simulation tools such as Spectre, ADS, HFSS or Momentum, Ansys Lumerical, COMSOL

• Knowledge of advanced packaging technology for optical engine integration in a co-package optics (CPO) solution

• Experience working on wideband circuit designs supporting high speed Serdes links with more than 100Gbps data rate and BW exceeding 10s of GHz

• Familiarity with high speed SerDes architecture, modulation schemes such as NRZ and PAM4 and link protocols

• Familiarity with optical and radio related test equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, high speed oscilloscopes and BERTs

• Experience characterizing EIC/PIC performance for high speed optical Serdes
