AI Engineer – Remote (Colombia)

About the role

Cadre AI is looking for a senior AI Engineer to join its remote delivery team. You will be the technical backbone that turns AI strategy into production‑grade systems for B2B clients across private equity, lending, real estate and SaaS. The role requires deep expertise in building, scaling and maintaining complex AI pipelines.

Key responsibilities

• Design and implement backend AI modules, including custom agentic workflows, multi‑step reasoning chains, and tool‑use pipelines.
• Translate architectural blueprints from AI strategists into high‑performance, production‑ready code with robust error handling, observability and latency targets.
• Own end‑to‑end delivery of AI components from scaffolding to deployment in client environments.
• Architect, optimize and troubleshoot Retrieval‑Augmented Generation (RAG) pipelines over unstructured, multi‑modal data.
• Implement and tune vector database solutions based on query patterns, data volume and latency requirements.
• Build and maintain agentic systems, managing tool selection, memory architecture and failure recovery.
• Identify recurring client needs and abstract reusable internal tools to accelerate future deliveries.

Required profile

• Proven experience delivering production LLM systems and fine‑tuning RAG pipelines.
• Strong ability to work autonomously, co‑developing requirements with strategists in real time.
• Track record of moving from prototype to production‑grade implementations without handoffs.
• Comfort with high‑pressure debugging of agentic chains and retrieval failures.

Required skills

• Large Language Models (LLM) development and deployment
• Retrieval‑Augmented Generation (RAG) pipeline design
• Vector database technologies
• Agentic workflow engineering
• Use of AI coding assistants for accelerated development
