Communications/DSP Associate Engineer Program (Winter 2025)
Astranis
Country: United States of America
Location: San Francisco
Time Type: Full Time
Posted On: September 27, 2024
Astranis is 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.
As a 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 (legendary) San Francisco office, which was once used to build ships during the World Wars.
Our satellites, which operate from geostationary orbit (GEO), weigh only 400 kg and utilize a proprietary software-defined radio payload. Each satellite can connect over two million people, and we’re very excited for the impact we’ll soon have in the Philippines, Peru, Mexico, and more!
Backed by substantial funding and a passionate, collaborative team, we offer a rewarding work environment where you'll learn and make a significant impact, no matter where you are in your career.
Apply and join us on our journey towards global connectivity!
Communications/DSP Engineer — Associate (Winter 2025)
Role
- Design signal processing for custom software defined radio hardware (ex. channelization, equalization, PA linearization, gain control, carrier synchronization, symbol mapping, framing, channel coding/FEC, etc)
- Work closely with FPGA developers to implement and test the signal processing on radio hardware
- Model the end-to-end radio system from earth to space, and back.
- Drive radio architecture trade studies, run link budgets, optimize the radio system for maximum performance for dozens of markets and use cases around the world
Requirements
- A passion for working in a fast-paced environment and constantly learning
- Strong fundamentals in "signals and systems" (basic transforms, filters, aliasing, analysis in both continuous and discrete domains, interpolation, decimation, etc)
- Strong fundamentals in digital communications (modulation, coding, synchronization, fading, doppler, multiple access, channel capacity, etc)
- Familiar with software development (some experience writing software for DSP, MCU, and/or FPGA, experience in one or more scripting languages)
- Familiar with analog concepts (amplifiers, analog filters, gain and delay variation, reflections, compression, etc)
- Experience working with signal generator, signal analyzer, network analyzer, oscilloscope, etc
- US Citizenship or Green Card
- Don't meet them all? Not a problem. Please apply even if you do not meet all these criteria.
Bonus
- Experience with software defined radios
