Job description

the company 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 the company is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

SR. RFIC DESIGN ENGINEER (RFIC ENGINEERING)

At the company 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 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 RF/Analog 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 RFICs 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. Join us to help deliver cutting‑edge solutions that will expand the performance and capabilities of the Starlink network.

RESPONSIBILITIES

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

BASIC QUALIFICATIONS

• Bachelor's degree in electrical engineering, computer engineering, or computer science
• 5+ years of 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
• RF/microwave design in the Ku‑band, K‑band and Ka‑band frequency range
• 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
