Anticipated pay range for this role: $80,000 -$120,000

Come break things (in a good way).

Then build them smarter.

We're the tech company everyone calls when things get weird.

We don’t wear capes (they’re a safety hazard), but we do solve high-stakes problems with code, caffeine, and a healthy disregard for “how it’s always been done.”
