Why this role exists: The purpose of this role is to build and operate LLM-based systems used in production. You will develop and integrate Generative AI solutions such as chatbots, AI assistants, MCP-based services, and other LLM-powered components within an existing ML and data platform. The focus is on practical, observable, and reliable systems that support knowledge-driven workflows, AI-assisted interactions, and automation. This is a hands-on engineering role with clear ownership boundaries and guidance from senior engineers.
What you’ll drive: LLM-based features and conversational systems — Implement and maintain LLM-based features and services under guidance. — Build and improve chatbots and conversational AI systems with predictable behavior. — Contribute to AI-assisted and AI-automated workflows that reduce manual effort.
RAG pipelines, agent workflows, and production integration — Work on RAG pipelines, including document ingestion, embeddings, retrieval, and generation. — Implement parts of agent-style workflows, including tool usage and step orchestration. — Integrate GenAI components with existing backend services and APIs.
System reliability and cross-functional collaboration — Help monitor system behavior, performance, and basic quality metrics. — Participate in debugging issues and supporting systems in production. — Collaborate with Product, ML Engineering, and Backend teams. — Follow team standards for code quality, testing, and documentation.
What makes you a GR8 Fit: Must-have — Solid background in software engineering. — Strong engineering fundamentals, including clean code, testing, and debugging. — Practical experience with Large Language Models, RAG architectures, and embedding-based retrieval. — Experience building chatbots or conversational systems, including tool or function calling and structured LLM outputs. — Familiarity with context or tool-serving patterns such as MCP or similar concepts. — Experience contributing to and supporting production systems. — Basic understanding of performance, latency, and cost considerations. — Experience working with AWS-based cloud infrastructure, including ECS, EKS, Lambda, S3, OpenSearch, and API Gateway. — Experience with Python and basic SQL. — Experience integrating third-party LLM APIs such as OpenAI or Anthropic, and working with Amazon Bedrock. — Experience working with open-source models such as LLaMA, Mistral, Mixtral, Qwen, or similar, and the Hugging Face ecosystem. — Experience with LangChain, LangGraph, Pydantic, and Langfuse. — Experience implementing embeddings and working with vector stores such as Qdrant, FAISS, OpenSearch, or pgvector. — Experience using Docker, Git, and CI/CD pipelines. — Familiarity with evaluation or monitoring of AI systems.
Nice-to-have — Knowledge of HiBob/Jira. — Expertise in C&B practices, approaches for the Spanish market. — Experience working with the employee reservation (military deferment) process in Ukraine.
