Careers
AI Engineer
Location: Ulaanbaatar · Full-time · On-site
Your primary focus is the AI layer itself — retrieval and embeddings, agent design, and the evals that keep agents accurate and reliable. You may also work on platform features and on customer agents.
What you'll do
- Design and improve retrieval — embeddings, chunking, hybrid search, and the strategies behind them
- Build and tune agents against real customer data, not just test data
- Write evals that keep agents accurate and reliable, and catch regressions before a customer does
- Improve the tools agents call, and how they decide to use them
What we look for
- 3+ years building production software, including AI or LLM-backed systems
- A deep understanding of how modern LLMs are built and how they work
- Production experience with LLMs — context and prompt engineering, agent design and evaluation frameworks
- Hands-on experience with embeddings and RAG strategies
- You measure results before and after a change, rather than assuming it worked
- Strong SQL, and comfortable in TypeScript
- Excellent with AI-powered tools such as coding agents
- Excellent work ethic, and a strong sense of responsibility and accountability
- Great communication and collaboration skills
