FPGA Engineer Intern

Aetherflux • San Carlos, CA

2d

About The Position

Aetherflux is building the infrastructure to power and connect the orbital economy. Our modular, scalable satellites collect sunlight in Low Earth Orbit to enable multiple integrated applications: transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit high-performance computing clusters (GPU/TPU), and providing secure, high-bandwidth optical data transport.
Current energy and data systems rely on complex logistics and outdated infrastructure. Aetherflux overcomes these challenges by enabling direct, on-demand, secure, and scalable energy distribution and data processing from space. This will fundamentally change how we operate in orbit and on Earth—supporting the rapidly expanding space industrial base, ISAM (In-Space Servicing, Assembly, and Manufacturing) operations, remote regions, and mission-critical environments.
Aetherflux was founded in 2024 by Baiju Bhatt. Inspired by his father’s work with NASA Langley Research Center, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before co-founding Robinhood, now a public company that has helped over 20 million Americans access the financial system.
Aetherflux has raised $90 million from Index Ventures, Interlagos, Construct Ventures, Breakthrough Energy Ventures, Andreessen Horowitz, NEA, and others.
This is an ambitious mission that demands extraordinary talent. Aetherflux’s team has worked at places like SpaceX, Astranis, NASA, Anduril, and the U.S. Navy, and is based in San Carlos, CA. If you're ready to solve complex technical challenges and help build a generational energy and infrastructure company, we want to hear from you.
As an FPGA Engineering Intern, you will work closely with our compute and hardware teams to design and implement high-performance digital systems that operate in demanding environments.
This role is ideal for someone who wants hands-on experience developing real systems that interface directly with hardware, sensors, and mission-critical infrastructure.
You will contribute to early-stage architecture and help bring up systems that are core to our platform.
