San Francisco, California, United States Astranis Full time
About Astranis

Astranis is a pioneering company on a mission to bridge the digital divide by connecting the four billion people worldwide who currently lack internet access. We're doing this by building the next generation of smaller, more cost-effective spacecraft to bring the world online.

Our Team

We've launched two satellites into orbit, signed ten commercial deals worth over $1 billion in revenue, raised over $500 million from top global investors, and recruited a team of over 300 world-class engineers. We all work out of our San Francisco office, which was once used to build ships during the World Wars.

Role Overview

As an RF Engineer, you will be responsible for designing, qualifying, and procuring active RF electronics (frequency converters, SSPAs, LNAs, PLLs, etc) in the RF front end of satellite payloads. You will work closely with other mechanical, payload systems, electrical, and software engineers to achieve overall system requirements in your designs.

Key Responsibilities
  • Design, simulate, implement, and measure active and passive RF sub-systems at microwave frequencies, including SSPAs, LNAs, power amplifiers, up/down converters, oscillators, filters, etc.
  • Be responsible for hardware designs from requirements definition through manufacturing, bring-up, and qualification testing.
  • Integrate these systems into the spacecraft by working closely with the rest of the team.
  • Specify, procure, and integrate third-party vendor hardware.
  • Assist in recruiting, interviewing, and hiring additional teammates to our rapidly-growing team.
Requirements
  • BS in electrical engineering, physics, applied physics, or equivalent.
  • Passion for hardware development, including working in a fast-paced environment and hands-on design and development.
  • 1-6 years of experience.
  • Deep knowledge of fundamental RF concepts, such as RF circuit analysis, noise, linearity, radio architectures, etc.
  • Hands-on experience in designing, building, and testing RF hardware for microwave frequencies.
  • Experience with RF simulation tools (ADS, Cadence, HFSS, etc).
  • US Citizenship or Green Card.
Bonus Requirements
  • MS or PhD in electrical engineering, physics, applied physics, or equivalent.
  • Experience with PCB design, layout, and simulation (Altium or similar).
  • Experience with system in package (SiP), multi-chip modules (MCM), packaged RF hybrids, etc.
  • Experience developing communications satellite payloads.
  • Experience designing SSPAs or implementing SSPA-based phased arrays.
  • Experience with designing high-reliability electronics for harsh environments such as space or automotive.
  • Antennas and Electromagnetics propagation knowledge and background.
  • Experience with Software Defined Radios and associated skillset (mixed signal, high-speed digital).
  • Familiarity with Python or other scripting languages used for automating test instruments.
What We Offer

All our positions offer a compensation package that includes equity and robust benefits. Base pay is a single component of Astranis's total rewards package, which may also include equity in the form of incentive stock options, high-quality company-subsidized healthcare, disability and life insurance benefits, flexible PTO, 401(K) retirement, and free on-site catered meals.

Astranis pay ranges are informed and defined through professional-grade salary surveys and compensation data sources. The actual base salary offered to a successful candidate will additionally be influenced by a variety of factors including experience, credentials & certifications, educational attainment, skill level requirements, and the level and scope of the position.

Base Salary: $120,000-$155,000 USD.

U.S. Citizenship, Lawful Permanent Residency, or Refugee/Asylee Status Required.

(To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States, or other protected individual as defined by 8 U.S.C. 1324b(a)(3)).

We believe in a diverse and inclusive workplace, and we encourage all people to join our team and bring their unique perspective to help make us stronger.
