Communications/DSP Engineer — Intern 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)
