Role overview
Software10 employees
Blaxel is AWS for AI agents. We’re a new kind of cloud computing infrastructure optimized for the unique demands of agentic AI, leveraging a purpose-built 25ms cold-start serverless compute engine.
Now processing billions of agent requests, we power the coding agents and background AI tasks infrastructure for top AI startups. Founders choose us when they hit the limits of general-purpose clouds. We solve the hard infrastructure problems—statefulness, ultra-low latency, and secure sandboxed code execution—so they can focus on building their core AI products.
We raised a $7.3M seed round led by First Round Capital.
What you will do
- Own the Blaxel Console experience from initial exploration and polished UI design to merging production-ready PRs.

Why this role is remarkable
- Shape a new product category by designing interfaces that serve both human users and autonomous AI agents directly.
- Join a high-growth startup with near-zero churn and strong revenue traction from AI agents already using the platform.
- Work directly with experienced repeat founders in a high-autonomy environment where your designs land in production immediately.
