About Astranis

Astranis is a company building small telecommunications satellites. It offers MicroGEO, a satellite designed for geostationary orbit (GEO) and powered by a software-defined radio. The company is aimed to provide users with internet access in remote regions.

Job Description

(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.

    • 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)
