Short version - You will make previews, sandboxes, deploys, logs, and telemetry feel instant, stable, and boring in the best possible way.
Why Mythos?
The builder experience depends on runtime reliability: every stalled preview or unclear deploy breaks trust.
This is high-leverage infrastructure work with a very visible product surface.
What you will shape
Own sandbox lifecycle, preview health, deployment handoffs, logs, and runtime observability.
Improve cold starts, caching, file sync, artifact storage, and recovery paths.
Build internal tools that let the team debug production incidents quickly.
Partner with frontend and agent engineers so system state is legible in the product.
What makes you strong here
You have operated production systems where speed, isolation, and reliability mattered.
You can design simple APIs around messy infrastructure constraints.
You like making hard systems feel uneventful for users and teammates.
You balance performance work with security and operational discipline.
