From the original posting

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.

PRINCIPAL RFIC DESIGN ENGINEER (STARSHIELD SILICON)

Starshield leverages SpaceX’s Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads. As a RFIC Engineer on the Starshield team, you will be working on advanced development programs in support of U.S. National Security. In this role, you will be developing cutting-edge next-generation RFICs for deployment in space and ground infrastructures around the globe. You will work in a highly collaborative and fast-paced environment, where we are exploring unsolved problems and applying the SpaceX mindset of iterating rapidly to go from design and demo to operational capability at lightning pace.

RESPONSIBILITIES:

  • Design, simulate and model RF/analog/mixed-signal circuits and systems
  • Derive specifications for the RFIC subsystems and circuits
  • Develop analog/mixed-signal/RF/microwave circuits in SiGe, GaAs, GaN, or CMOS processes
  • Work with system architects, modem/DSP and ASIC engineers to partition functions between hardware and software domains
  • Perform IC floor planning and layout
  • Own packaging prototypes, product development, and release to production. Model package and external parasitic components
  • Evaluate and characterize prototypes of the design
  • Assist in the development of automated test lab equipment for lab measurements
  • Work with manufacturing engineers on production testing and qualification of the RFIC components and systems

BASIC QUALIFICATIONS:

  • Bachelor's degree in electrical engineering, computer engineering, or computer science
  • 8+ years of professional RF integrated circuit experience

PREFERRED SKILLS AND EXPERIENCE:

  • Master's degree or PhD in electrical engineering or computer engineering with an emphasis in RF/analog/mixed-signal integrated circuit design
  • Experience using simulation tools such as Spectre, ADS, HFSS or Momentum
  • Circuit design skills, and experience performing analysis and simulation of both linear and non-linear circuits such as phase-locked loops, vector modulators/demodulators, oscillators, mixers, filters, low noise and power amplifiers
  • Knowledge of digital communication systems, spread spectrum, single and multi-carrier techniques and modulation types such as QPSK, APSK and QAM
  • Knowledge of RF transceiver architectures
  • Deep understanding of theory and MMIC design of RF front end blocks, from S-band to W-band frequency ranges
  • Familiarity with radio related test equipment such as spectrum analyzers, vector signal analyzers, vector signal generator, network analyzers
  • Experience characterizing radio performance in microwave frequencies

ADDITIONAL REQUIREMENTS: 

  • Ability to work long hours and weekends as necessary to support critical milestones 
  • Willingness to travel for off-site testing
  • An active clearance may provide the opportunity for you to work on sensitive SpaceX missions; if so, you will be subject to pre-employment drug and random drug and alcohol testing

COMPENSATION AND BENEFITS:

Pay Range:
Level 3: $210,000.00 - $340,000.00

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.
