Hey, I’m [Teddy](https://www.linkedin.com/in/teddy-ni/), 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:
**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!
