About the role
Job Description:
We are seeking an AI Product Engineer. For us, this role combines the following: a senior-level backend/full-stack engineer who will not only code, but also write prompts and perform prompting data engineering—and who is a big gaming enthusiast.
-
Prompt/Context/Data Engineering to improve 3 of our 7 LLM agents and RAGs that are responsible for on-time order-completion tracking, order planning, and customer-success facilitation.
-
Gaming-API integrations and data engineering (you’ll start with Destiny 2, WoW, and CoD).
-
Most important: you’ll work hands-on with users, and we don’t expect you to manage any team.
We have a small and mighty engineering team with a flat structure, where everyone is responsible for delivery from beginning to end without passing tasks around the team.
About Us:
Legionfarm connects gamers with professional players for carries, coaching, and other in-game services through Discord, SMS, a desktop app, and web marketplaces. We are building vertical LLM agents to help pro players manage their sales, order success, content, schedules, hiring, and more. We’ve facilitated several million LLM customer-service interactions with a monthly token burn of 2.55 B, and we have been focusing full-time on agent and AI-infrastructure building since March 2023. We believe we have one of the most advanced AI infrastructures across all existing marketplaces in the world. Come and see 🙂
Responsibilities:
- Code in PHP or Python to support back-end development.
- Connect gaming APIs and use your gaming expertise (and pros) to figure out every user flow.
- Develop and optimize AI prompts and data placeholders.
- Synchronize daily with the Product, Engineering, and Founding teams.
What We Offer:
You will work on the frontier with a team of highly experienced people.
