Job description

Job Title: Senior ML/LLM Engineer – AI Agents & Fine-Tuning

Location: Remote (Part-time or Full-time)

VinoVoss is the flagship project of BetterAI, redefining wine discovery through an AI-powered virtual sommelier that combines natural language processing, semantic search, and conversational AI. We're on a mission to build one of the most intuitive and intelligent recommendation engines in consumer tech—and we’re looking for a Senior LLM Engineer to help bring this vision to life.

What You’ll Do:

• Fine-tune large language models for domain-specific conversation and recommendation
• Design intelligent, tool-using agents with multi-step reasoning and memory
• Implement and experiment with frameworks like LangChain, LangGraph, or Google’s Agent Developer Kit (ADK)
• Integrate with Vertex AI and other foundation model platforms for inference, embeddings, and orchestration
• Collaborate across front-end, backend, and AI teams to deliver seamless end-user experiences
• Stay on the edge of LLM trends—streaming, multimodality, and interactive agents

What We’re Looking For:

• 4+ years of experience with LLMs, including model fine-tuning and deployment
• Proficiency in Python and modern AI tooling (e.g., LangChain, LangGraph, OpenAI, Hugging Face)
• Experience designing agent workflows, including context management, tool-calling, and chaining
• Familiarity with Vertex AI, cloud APIs, or comparable ML platforms
• Bonus: experience with real-time applications, embeddings, or multimodal input
• Strong collaboration and communication skills in a remote, fast-paced environment

Why Join Us?

This is a rare opportunity to own LLM development at a consumer AI company—and help shape the future of human-AI interaction beyond text. We offer flexible hours, a supportive and ambitious team, and a chance to build something people love.
