Hey, I’m Teddy, CTO & co-founder at Magic Patterns! Our engineering team has grown a lot over the last few months here in San Francisco. you can check out our careers page here: https://www.magicpatterns.com/careers

About Magic Patterns
Our mission is to let anyone build delightful software. We're a lean team where everyone contributes directly to the product.

If you’re an AI engineer, our roadmap is probably a goldmine of things you’ve always wanted to work on:

  • An AI agent that thousands of users use religiously everyday

  • Evals with a self-improving agent loop

  • Context engineering

  • Post-training on design output

The most common piece of feedback we get is "I tried a bunch of tools but your design quality output is by far the best." We want to push the limits even further.

About this role

  • Own our eval system that feeds into our self-improving agent loop

  • Push and define the limits of what AI can do in design. Today, we are state of the art, and we want to continue to push that.

  • Collaborate with the product team to bring novel solutions to improve agent quality from the perspective of our users

  • Decide what to work on to improve our AI Design agent. The list above are open problems, not assignments

This role might be a fit if you...

  • Use AI tools in your daily workflow

  • Have experience with AI models and/or have worked on an AI agent before

  • Have experience building eval systems, post-training, context engineering

  • Strong first-principles thinker that can distill complex problems

Our Values

  1. Obsessive — we love exploring every corner of the hardest problems.

  2. Growth-minded — where you are today matters less than how fast you are growing

  3. Ownership — insist on high standards and craftsmanship.

  4. Spread the magic — for many people, Magic Patterns is “magic.” Be proud of your work and have fun!

Compensation and benefits:

  • Rapid career growth at one of the fastest growing Series A companies

  • Competitive salary and equity package

  • 20 days off PTO

  • Health, dental, and vision coverage

  • Fun team offsites and events — we went to Mexico last year!
