About the role
Here at Spellbrush , we're passionate about making a good anime game.
We also happen to be the world's leading generative AI studio — we're the team behind niji・journey.
We are currently investigating how AI can be used to help human artists perform masterpieces in the most complex medium of our times: videogames.
Our games are characterized by a no-compromise approach to well-balanced gameplay married to a truthful love of visual arts.
If you love turn-based tactics games, please consider applying!
The Role:
Spellbrush, the world’s leading generative AI studio behind_ niji・journey __ , _ is looking for an LLM Prompt Engineer to bring the characters and world in our mobile turn-based tactics game to life with distinctive flair! If you love games like Fire Emblem and Final Fantasy Tactics and are eager to utilize Generative AI to create evocative gameplay experiences, please apply!
What you’ll do:
-
Become the power user and wizarding wordsmith of our LLM models, coaxing out new turns of phrase, emotional responses, and vivid imagery through imaginative prompt engineering.
-
Deeply understand our next flagship game’s core narrative, themes, and character motivations and conflicts – then translate these elements into elegant LLM prompts.
-
Work with our Creative Director to develop new systems for enabling our game’s characters to freely express themselves in the native game platforms where they interact with players.
-
NOTE: You do not need to be currently involved in LLM research or an AI / ML expert to apply - we highly value your writing and creative ability.
You might be a great fit if:
-
You endeavor to use LLM’s to revolutionize character communications.
A familiarity with text-based Generative AI and LLM is definitely handy, but moreso than that you understand that LLM’s are working off of datasets and training, and that your finesse in guiding the models will produce outstanding delights of diction.
-
You’re eager to push the boundaries of written and verbal communications.
Part of the challenge (and excitement) of using LLM’s is that they can produce combinations of words and phrases to produce meanings, mental images, and interactions never before imagined.
Maybe you’ve devised a new alien language for a sci-fi novel or a mana system for an underground race of mushroom people. Whatever it is, going beyond the norm in your creativity will help our LLM models reach their limitless potential.
-
You understand what it means to be human, and how our human tendencies emerge in conversation.
To make authentic and genuine conversations, we believe the author (or in this case, prompter), should have a deep familiarity with the nuances that make language feel more “human”. Whatever your mode of introspection and emotional exploration, we’d love to know (and support it)!
