## Description

We're hiring a Developer Relations Engineer to help the open source community build with Thinking Machines' products - Inkling and the models that follow it, and Tinker, our fine-tuning platform. You'll work hands-on with real users, turn their feedback into product improvements, and help developers get the most out of our models and tools.

This role sits at the intersection of engineering, research and community: you'll write code, ship industry leading ML recipes and integrations, and also represent Thinking Machines externally through talks, demos, and technical writing. It's a great fit for someone who's happiest building in a code editor, but who also enjoys teaching and engaging with a fast-growing developer community.

What You'll Do

 * Write, test, and maintain high-quality agentic training, code examples and documentation for Inkling and Tinker
 * Work directly with developers and researchers in the open source community to debug issues, gather feedback, and improve their experience fine-tuning and deploying models
 * Partner with the research and infrastructure teams to turn community patterns and feedback into concrete improvements to Inkling, future models, Tinker, and develop new post-training recipes.
 * Build demos, integrations, and tools that make it easier for developers to adopt and get value from Thinking Machines' models
 * Represent Thinking Machines in the open source community through blog posts, talks and tutorials, livestreams, and conference and meetup appearances
 * Help shape the developer experience roadmap as new models and platform features ship
