About this role
Role Overview
- You will be the engineering pillar of the Data & AI Tribe.
- Your mission goes far beyond coding: we expect you to transform AI prototypes into robust, scalable, and observable software products.
- You will be the technical reference to ensure our solutions (such as legal assistants and data extraction systems) operate in production with high availability.
- Architect and develop the backend for LLM-based applications, ensuring they are fast, cost-efficient, and reliable.
- Implement end-to-end RAG (Retrieval-Augmented Generation) pipelines, handling everything from data ingestion and intelligent chunking to retrieval strategies and response generation.
- Create and maintain Autonomous Agents that perform complex tasks, ensuring they have control mechanisms, memory, and error handling (to avoid infinite loops or hallucinations).
- Lead architectural definitions, conduct rigorous code reviews, and raise the team's technical bar.
- Work side by side with Product Managers and Designers to translate vague business problems into viable technical solutions.
Requirements
- At least 5 years of hands-on software development (Backend) experience, with recent years focused on or transitioning to AI/Data projects.
