To make new things you need to care
You need to care so much
Otherwise it’s just slop

I’m thankful for 4 years in California .
But, the Next Phase is in Texas.
We shift our hiring focus to build huge operations in Austin, Texas.
Join us ! The team is really great. @fab2

Software should be fun and fast

We are building Atomic Studio to match the speed of our fab. It’s fast, browser-based, and collaborative. Layout, schematic, and simulation.
Here’s a side by side of Studio (left) and Klayout (right) moving through the same file.

We're building something with Rust WGPU, billions of polygons, field simulations, fast multiplayer sync, constraints, auto-routing, lots of graphs, etc at Atomic Semi right now.

We talked to a few hundred students at Waterloo and CMU this week about building small, fast semiconductor fabs. Interns build the hardware and software tools in our fab. You get a credit card, space in our lab, machine shop access, and great mentors. The rest is up to you.

We make it ourselves
And make the machine to make it.
Want to join?
Hiring EE, ME, Software , process engineers. We made the machine that puts atoms there, it’s laptop sized and draws 90 watts . Now we’re automating and building 10.

We thought about planning to manufacture more semiconductor fab tools than the world combined, but it’s really a sadly low goal . Think like intermediate milestone .
