We are looking for an analytical, automation-driven, and technically versatile professional who thrives at the intersection of AI systems, workflow automation, and customer operations. The AI Automation Engineer combines deep technical expertise in LLM-powered agents and REST API integration with a clear understanding of customer service workflows — building intelligent systems that transform how support operates at scale.
The idóneo candidate moves fluidly between designing a multi-agent architecture, building an N8N automation workflow, iterating on an LLM prompt, and integrating elements like API calls in data pipelines — all while keeping the end-user experience and operational excellence at heart. They take full ownership of projects, document as they go, and know how to unblock themselves.

MAIN RESPONSIBILITIES:
AI Agent & Automation Development
- Design and build multi-agent AI systems integrating LLMs for end-to-end customer-facing workflows: email triage, refund processing, escalation logic, voice bot interactions.
- Develop and maintain N8N automation workflows.



Mid knowledge of python and javascript are required for code node scripting.
- Integrate voice AI platforms (e.g. Retell AI, ElevenLabs, ConnexAI, Vapi, BlindAI, etc.) with custom prompt logic for call bot behaviour, customer handling, and multi-step flows.
- Classify and prioritize automation use cases based on business impact, technical complexity, and urgency.
- Ensure every automated workflow reflects high-quality communication standards, SLA adherence, tone consistency, and operational resilience.

API Integration & Technical Analysis
- Define, document, and test REST APIs for integration with CRMs, helpdesk platforms (Freshdesk), and internal systems across multiple product versions.
- Perform initial technical assessments of integration issues by reviewing API responses, logs, configurations, and system outputs to detect errors or inconsistencies.
- Build and manage comprehensive API test su
