Senior AI Engineer: LLMs, RAG & MLOps

Solvedex; Colombia; Presencial; COP 120.000.000 - 180.000.000; Jornada completa

Descripción de la vacante

Solvedex is hiring an AI/ML Engineer to design and build scalable AI features for a fast-growing Talent-as-a-Service startup. You’ll work on LLM-based products, RAG pipelines, and production-grade Python services, collaborating with product managers and engineers.

You will deploy models on cloud platforms (AWS/GCP/Azure), implement MLOps, and optimize for latency, cost, and reliability while advancing AI capabilities for client projects.

Formación

• 4–7 years of experience in Software Engineering, Machine Learning, or AI Engineering roles.
• Strong Python skills and production-grade applications.
• Hands-on experience with LLMs (OpenAI, Anthropic, or similar) and API integration.
• Experience with RAG architectures, embeddings, and vector databases (e.g., Pinecone, Weaviate, FAISS, pgvector).
• Solid understanding of ML fundamentals and frameworks such as PyTorch or TensorFlow.
• Experience with cloud platforms (AWS, Azure, or GCP).
• Familiarity with MLOps: CI/CD, model versioning, monitoring, experiments.
• Strong APIs, data pipelines, and system design for AI-driven products.
• Advanced English (C1) for cross-cultural collaboration.
• Ability to operate in fast-paced, evolving environments.

Responsabilidades

• Design, build, and deploy AI-powered features and applications, including LLM-based products (chatbots, copilots, agents, RAG systems).
• Develop and integrate solutions using LLM APIs (OpenAI, Anthropic, or similar) and open-source models.
• Build and maintain Retrieval-Augmented Generation (RAG) pipelines, including chunking, embeddings, and vector database integration.
• Design and implement prompt engineering strategies, fine-tuning, and evaluation frameworks to improve model performance and reliability.
• Write clean, production-grade Python code for AI/ML services and pipelines.
• Deploy and monitor models and AI services in cloud environments (AWS, Azure, or GCP).
• Implement MLOps best practices: versioning, CI/CD for ML, experiment tracking, and observability.
• Optimize latency, cost, and scalability in production AI systems.
• Collaborate with product managers and engineers to translate business problems into AI/ML solutions.
• Evaluate models and tools for each use case (build vs. buy, open-source vs. API-based).
• Document architecture, experiments, and decisions for long-term maintainability.
• Stay current with AI landscape and bring new techniques to the team.
