AI Automation Engineer

This is a fully remote position, open to applicants in Spain.

📋 Description

• Design and develop multi-agent AI systems that incorporate LLMs for comprehensive customer-facing processes, including email triage, refund processing, escalation logic, and voice bot interactions.

• Create and manage N8N automation workflows, requiring intermediate knowledge of Python and JavaScript for code node scripting.

• Integrate voice AI platforms (such as Retell AI, ElevenLabs, ConnexAI, Vapi, BlindAI, etc.) with custom prompt logic to enhance call bot behavior, customer handling, and multi-step flows.

• Assess and prioritize automation use cases based on their impact on the business, technical complexity, and urgency.

• Guarantee that every automated workflow meets high communication standards, adheres to service level agreements, maintains tone consistency, and ensures operational resilience.

• Define, document, and test REST APIs for integration with CRMs, helpdesk platforms (like Freshdesk), and internal systems across various product versions.

• Conduct initial technical evaluations of integration issues by analyzing API responses, logs, configurations, and system outputs to identify errors or inconsistencies.

• Develop and maintain comprehensive API test suites in Postman and N8N, addressing edge cases and structured regression scenarios.

• Work collaboratively with Development, Product, and QA teams to reproduce, diagnose, and escalate complex technical challenges efficiently and with thorough context.

• Engage in regular meetings with technical leads to pinpoint recurring automation gaps and spearhead process enhancements.

• Create and refine LLM prompts for structured output generation, including JSON schema enforcement, multi-category classification, sentiment analysis, and application reference extraction.

• Troubleshoot and enhance AI pipeline outputs, resolving inconsistencies in model responses.

• Utilize knowledge of AI delegation and orchestration patterns to design dependable, scalable agent workflows.

• Identify ongoing workflow gaps or automation opportunities and propose preventive or optimization measures.

• Contribute to internal technical documentation, API specifications, runbooks, and workflow guides to foster team efficiency and knowledge sharing.

• Assist in the onboarding and upskilling of new team members regarding automation tools, AI systems, and integration patterns.

• Collaborate with cross-functional teams on initiatives aimed at improving customer experience and streamlining operational workflows.
