About Spellbrush

We're a small, tight-knit team of MIT-trained researchers applying the latest advancements in deep learning for anime and video games. You might know us from our viral internet meme site waifulabs.com

Our AI artist assistant helps illustrators and animators finish pieces up to 10x faster by automating away much of the manual labor involved in shading, rendering, and coloring.

None of the above three images were drawn by human artists. All three were drawn entirely by artificial intelligence! No human post processing involved.

We can also get the AI to animate our generated characters too if we ask nicely enough!

About the role

Skills: React Native, TypeScript, CSS, React, Elixir, Unity

We're looking for a talented Full-Stack Engineer to join our small team of world-class artist and engineers in building the world's first ML-powered game!

We have a Game UI frontend that is pushing React Native to its absolute limits, a distributed backend powered by Phoenix & Elixir, and a huge fleet of auto-scaling ML inference servers powered by Python & Kubernetes.

Did I mention our game also has a sick future-core soundtrack and an awesome animated intro via a Japanese studio?


  • Experience in front-end technologies like React/React Native, especially w/ navigation stacks and some simple transitions and user experience.
  • Experience with Elixir/Phoenix, but we're also happy with Django/Rails or equivalent experience as we can teach the relevant skills.
  • Strong aesthetics in anime-based mobile games (FGO, P&D, Arknights, etc.)
  • Bonus: familiarity with Unity 3D & C# scripting.
  • Excited about the possibilities of AI — no AI/ML experience needed; we're more than happy to teach you the tech skills and intuitions needed.


As the 6th member of our team, you'll be intimately involved in all aspects of the product, from design, production, and marketing.

  • We're a fast-paced startup with funding from some of the world's leading VCs.
  • Our office based in downtown San Francisco, CA directly next to all major transportation. (Or not. We're remote work friendly)
  • Market salary + above-market equity compensation.
  • You'll work alongside our world-class AI researchers to develop the next software revolution in art.
  • We have top-of-the-line health insurance, dental insurance, and all that other good stuff.
  • Give us a ping if you want to be on the cutting edge of the next revolution in games!

To apply:

  • Include a link to a portfolio or existing app showcasing your frontend engineering.
  • Please include the name of best waifu/husbando in your application.


At Spellbrush, we're pushing the boundaries of generative networks through our state-of-the-art GAN research.

  • Research: We use a lot of Tensorflow and the supporting ecosystem. We run large-scale ML experiments on a daily cadence on a mixture of GCE, AWS, as well as our on-premise GPU clusters. Our researchers spend each day developing and testing novel and experimental architectures.
  • Infrastructure: We've built our own mini in-house supercomputer with lots of GPUs and a high-performance parallel file system over 100GbE fabric. As part of our Infra/Devops team, you'd help mange our entire stack, from deploying data-center-grade switches, to improving our hybrid-cloud job submission system.
  • Engineering: Functional coders rejoice -- our backends are primarily in Elixir, with a bit and Python scattered here-and-there. We also have a lot of simulation and game logic code written in C# via Unity!
