AI Prompt Writer

Every month we are proud to be home to 300 million users around the world. Brainly’s knowledge base consists of hundreds of millions of Q&A content in more than 12 languages and covers a broad spectrum of educational subjects at different grades.

Our AI strategy and roadmap are investing more and more in our capacity to best exploit modern LLMs and build domain-specific layers around them. Being able to design and craft optimal prompts is fundamental for our success.

We would like to establish a Prompt Optimization team with a specific focus on tailoring and optimizing prompts for LLM-powered product features at Brainly.

The team will dedicate efforts to constantly researching and experimenting with the S-O-T-A and applying it to our business domain.

Thus, supporting production teams developing product features with LLMs, while the Prompt Optimization team figures out and optimizes the underlying prompts for improving the quality of generated answers and the corresponding user satisfaction.

You will impersonate the roles of the teachers and the students of our platform in order to instruct and assess our AI to behave according to their expectations and satisfy their learning goals.

You will have the chance to work with top-class data scientists, ML engineers, and domain experts, and to contribute to the R&D processes of our LLM-based product features.

The ideal candidate is a native (or very advanced) English (US) speaker, an expert in content writing, with a background in teaching and/or equivalent experience in education, and most importantly motivated to work full-time to master the art of prompt engineering.

Are you passionate about Generative AI, and you have creative problem-solving abilities, and an eye for detail?

Are you able to draw conclusions from data and propose recommendations?

Can you imagine yourself prototyping and testing suboptimal solutions?

If you answered "yes" to these questions, you might be a person we're looking for!

Are you a native English (US) speaker or are fluent in American English?

Then the fit couldn’t be better!

Please, note: No prior technical experience is required.
