Descripción de la vacante

Coderio is seeking an autonomous Senior Backend AI Engineer to own end-to-end backend and AI infrastructure for scalable live AI products. You will work with a product owner and senior engineers in an agile pod, delivering high-performance services in Python.

The role emphasizes production-ready RAG systems, LLM observability, prompt versioning, model/data drift monitoring, and tight integration with vector databases such as Pinecone. Fluency in English and strong independence are required.

Formación

• 5+ years of overall software development experience with a heavy focus on backend systems.
• 3+ years of production-level engineering experience with Python.
• 2+ years of hands-on experience building, deploying, and maintaining Retrieval-Augmented Generation (RAG) systems in live production environments.
• 1+ years of hands-on experience integrating and utilizing LLM observability and tracing tools (e.g., LangFuse, LangSmith, or equivalent platforms).
• 1+ years of experience establishing prompt versioning, A/B testing, and evaluation frameworks for LLMs.
• 1+ years of experience implementing data drift and model drift monitoring for production AI workloads.
• Fluent English (spoken and written) for daily technical collaboration with US-based teams.

Responsabilidades

• Refactor, maintain, and scale the core backend and AI framework layers of the platform, eliminating technical debt to support multi-tenant growth.
• Implement and monitor production LLM observability, focusing on token cost optimization, retrieval strategy tuning, and real-time model/data drift detection.
• Build and manage automated prompt versioning systems, A/B testing pipelines, and LLM evaluation frameworks to ensure high response quality and consistency.
• Build out next-generation copilot services and agentic workflows that autonomously produce structured communications (emails, text messages, and call scripts).
• Deliver reliable Python backend services, integrations, and APIs that interact directly with vector databases (Pinecone) and LLM providers.
• Drive features from concept to production, working directly within client cloud environments while maintaining strong code quality and operational standards.
