DX/AX Engineer

Blaxel•San Francisco, CA

About The Position

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.

Requirements

A DX fanatic: You have a proven track record of owning and dramatically improving developer experience at a top-tier, developer-first platform (e.g., Vercel, Render, Fly.io, GCP).
A builder and an architect: You are a strong software engineer who isn't afraid to dive deep into the codebase to build new SDKs, improve a CLI, or refactor an API for clarity.
Proficient in Python, TypeScript, and Go: You have strong development skills across these three languages.
Deeply AI fluent: You understand the emerging patterns of agentic AI. You're excited by the challenge of designing interfaces for agents, not just humans.
User-obsessed: You possess deep empathy for developers. You feel physical pain when you see a confusing API, a bad error message, or a convoluted user flow.
An execution machine: You have a bias for action and a proven track record of shipping. You thrive on a high-velocity, results-oriented team.
Ideally, you’ve even been a founder and built your own product and brought it to market.

Responsibilities

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.
Obsess over API parameter naming and error message clarity to the logical flow of our documentation and guides.
Actively design and implement clever interfaces and protocols optimized for consumption by AI agents, not just human developers.
Define and track key DX/AX metrics, relentlessly measuring and improving "time to aha moment," "time to successful implementation," and overall platform adoption.
Work closely with our Developer Advocate to gather user feedback and translate it into actionable engineering and product improvements.
