About the role
About Blaxel
Blaxel is the perpetual sandbox platform for AI agents that need to run code fast. We let you keep infinite, secure code sandboxes on automatic standby while co-hosting your agents for near instant latency. This is enabled by our own technical backbone: a 25ms cold-start serverless compute engine.
Now processing billions of requests, we power the coding agents and background AIs for top AI startups & scaleups like Webflow or HumanBehavior. We solve the agentic infrastructure problems that traditional clouds aren’t built for, such has running AI code securely, statefully and with ultra-low latency — so that AI companies can focus on building generational products.
We raised a $ 7.3M seed round, led by First Round Capital.
The role
We're looking for a world-class Developer Experience Engineer to define and own the developer experience for our groundbreaking AI infrastructure across all interfaces, features and products.
You'll be fundamentally designing how developers (and AI agents) interact with our platform. Your mission is to obsessively drive down the time, frustration, and effort it takes our users to go from "what is this?" to "wow, this is powerful.".
Your user isn't just human. You will be a pioneer of Agentic Experience (AX), designing interfaces so seamless and clever that AI agents can consume our platform as easily as developers. If you are a builder who believes that a world-class DX is a product's most critical feature and are excited to define it for a new category of cloud computing, this role is for you.
What you'll do
-
Design, build, and improve the developer experience across all platform interfaces, including maintaining our CLI, SDKs, and MCP servers that make our platform a joy to use.
