What are the responsibilities and job description for the Sr. Avionics Engineer position at Aetherflux?
Senior Avionics Engineer (Seattle, WA)
About Aetherflux
Aetherflux is building the infrastructure to power and connect the orbital economy. Our satellites operate in Low Earth Orbit to collect sunlight and enable a new class of capabilities—from transmitting energy via infrared lasers (space-to-earth and space-to-space), to powering on-orbit compute, to delivering secure, high-bandwidth optical data. By rethinking how energy and data are generated and distributed in space, we’re unlocking entirely new ways to operate both in orbit and on Earth.
Founded in 2024 by Baiju Bhatt (co-founder of Robinhood), Aetherflux is backed by leading investors and built by a team from top aerospace and defense organizations. We’re moving quickly to solve complex technical challenges and build a new category of space infrastructure.
The Role
The Senior Avionics Engineer is responsible for the design, development, and integration of electrical systems supporting advanced optical and laser satellite payloads. This role will require hands-on work with both electrical and optical components to ensure seamless integration of high-power laser systems and payloads for Aetherflux satellites. You will collaborate with optical, mechanical, software, and systems engineers to develop solutions that meet rigorous performance standards for space applications. This is an in-person role at our Seattle, WA location. You would join us on an aggressive timeline and see your work in space as we conduct our first space demonstration in the summer of 2026
