Communications Systems Engineer

Astranis, San Francisco, CA

Building the future of telecommunications satellites.


U.S. CITIZENSHIP OR GREEN CARD REQUIRED
(Note: This is due to U.S. export regulations, and we are unable to make exceptions.)

Four billion people do not have access to the internet. Astranis is going to change that. We are building the next generation of smaller, lower-cost telecommunications satellites to bring the world online. 

Come work with incredibly smart people who have flown things in space before. No prior space experience needed, you just need to enjoy getting your hands dirty with real hardware and be okay with struggling to do things that seem impossibly hard.

We’re a well-funded team of over 100 world-class engineers that move fast. We raised our Series B ($90M) from Andreessen Horowitz and Venrock, launched our first satellite in 2018, secured our first major customer deal in 2019, and we’ll triple the satellite internet capacity of Alaska in 2021. 

Our mission and our products are meant to connect the world and everyone in it, regardless of gender, race, creed, or any other distinction. 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.

Role

  • Design, test and deploy communications related signal processing algorithms, including modem
  • Characterize and calibrate radio hardware in the lab
  • Develop accurate, end-end simulation model for custom radio system
  • System budgeting and link analysis

Requirements

  • Bachelor of Science degree in electrical engineering or equivalent
  • Strong technical communication skills (oral and written)
  • Experience leading a technical project which included at least one other full time engineer
  • A passion for working in a fast-paced environment and constantly learning
  • Proven ability to triage and debug issues discovered in testing
  • Strong fundamentals in "signals and systems" (basic transforms, filters, analysis in both continuous and discrete time, etc) 
  • Strong fundamentals in digital communications (modulation, coding, synchronization, fading, equalization, etc)
  • Comfortable working in the lab, testing radio hardware, using signal generator, signal analyzer, network analyzer, oscilloscope, etc
  • Familiar with analog components and associated impairments (gain and delay variation, ISI, compression, phase noise, LO feedthrough, image rejection, etc)
  • Familiar with software development (Python, and some C/C++), and fast to learn new tools
  • Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria.

Bonus

  • RF system design and budgeting
  • Radio characterization test planning, automation and execution
  • Comfortable with software, especially Python, git, GNU Radio
  • Fixed point implementation of signal processing algorithms
  • Familiarity with multi-rate signal processing techniques (polyphase filters, resamplers, etc)
  • Multi-antenna systems (beamforming, null-steering)
  • Direct sequence spread spectrum (DSSS) modem design
  • Familiarity with satellite waveforms and modems (DVB-S2/x, DVB-RCS2)
