Descripción de la vacante

Finom is seeking a Senior AI Engineer to design, build, and operate AI systems that solve real business problems across our platform. You will move from prototype to production, shaping the solution, building the system, and measuring quality.

You will work on onboarding, customer care, accounting automation, fraud detection, and document understanding, collaborating with product and engineering teams to deliver production-grade capabilities that create clear value for users and the business.

Formación

• Proven experience building and deploying AI systems in production.
• Strong Python and software engineering fundamentals.
• Hands-on experience with LLM applications, including RAG, tool use, agents, prompt engineering, evals, structured outputs, guardrails, or fine-tuning.
• Experience integrating AI systems into backend or product workflows.
• Ability to design meaningful evaluation, monitoring, and continuous improvement loops.
• Experience with cloud infrastructure and containerized deployments.
• Strong ownership mindset and ability to work through ambiguity.
• Actively experiments with new AI models, tools, and agentic patterns, and can evaluate which approaches are worth productionizing.
• Fluent English.

Responsabilidades

• Build and ship AI-powered product and internal solutions using LLMs, RAG, tool calling, workflows, and agentic patterns.
• Own AI systems end-to-end: problem framing, architecture, implementation, evaluation, deployment, monitoring, and iteration.
• Partner closely with solution managers, domain teams, and engineers to integrate AI into real workflows rather than isolated demos.
• Design quality and evaluation frameworks for AI systems, including offline evals, online signals, failure analysis, and continuous improvement loops.
• Develop scalable and reliable inference pipelines with strong attention to latency, cost, security, and observability.
• Work on use cases such as onboarding, customer care, transaction and document classification, knowledge assistants, fraud detection, and operational automation.
• Contribute to AI platform and tooling decisions that improve reuse, speed, and consistency across teams.
• Challenge assumptions, propose better approaches, and help shape the roadmap rather than only execute tickets.
• Experiment boldly, learn quickly from failures, and turn insights into stronger systems and better practices.
