**We are looking for a Fullstack Engineer with experience in LLMs to help build and ship production-grade software and workflows for clients in the US and Europe.**

You’ll work across the stack – from frontend to backend and model integration – collaborating closely with product leads and other engineers to turn ideas into working systems.

This is a remote-first role, though candidates based in Vienna can also work with us in person if preferred.

## Tasks

*   Design, develop, and deploy LLM-powered applications, including but not limited to fine-tuned models and retrieval-augmented generation (RAG) pipelines, while exploring innovative ways to enhance AI-driven workflows
*   Build and maintain scalable fullstack applications using a Python or JavaScript-based stack (Node.js, React, etc.), along with applications for advanced data processing, data handling and model integration
*   Prototype and refine agentic workflows using n8n and similar low-code/no-code platforms to quickly validate solutions first

## Requirements

*   2+ years of experience as a fullstack developer, with a strong background in JavaScript-based and Python-based technologies
*   1+ years of deep understanding of LLMs, fine-tuning, vector databases and retrieval-augmented generation (RAG), along with a strong overall interest in the AI space to stay on top of developments
*   Understanding of data science principles, including data preprocessing and model evaluation
*   Strong problem-solving skills and the ability to work independently
*   Fluency in English

## Benefits

*   Flexible working hours
*   Remote setup or optional in-person work in Vienna, Austria
*   Insight into cutting-edge AI and automation projects

**Why join Waterglass?**

*   Opportunity to go beyond building agentic software applications – play a central role in creating AI-driven business ventures from scratch, combining technology, strategy and execution
*   Work with cutting-edge AI technologies that have real-world applications, solving complex problems for both our own ventures and international clients across the US and Europe
*   Join a small and fast-moving team with expertise in product, growth, and finance, where your contributions directly shape the direction of new AI-powered businesses
