Communications/DSP Intern (Fall 2024)

Internships at Astranis typically last for twelve weeks, and are hourly roles designed for students who are currently enrolled at a four-year university. 

 

As an Intern, you will have an amazing opportunity to work on hard problems - we pride ourselves on giving everyone at Astranis a chance to do meaningful work on challenging projects, no matter their seniority. Many past interns have designed and tested hardware/software that is heading to space on our first satellite, and many of them are now full-time employees at Astranis. 

 

If you have already graduated from a four-year university, please apply to be an Associate Engineer.

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
• 40 hours per week minimum
• Must be onsite in San Francisco 3 days a week minimum
• 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
• Experience with Python
• Experience with GNU Radio
• Experience with FPGA development (and/or embedded C)
