Role Overview

We are seeking a hands-on AI Engineer to design, build, and deploy practical AI solutions within our Customer Service ecosystem. This role is focused on delivering production-ready AI solutions, not research or purely model-training. The successful candidate will collaborate closely with Customer Service, Automation, CRM, and Platform teams to identify operational pain points and translate them into effective AI solutions. Key responsibilities include building AI Agents, LLM-powered workflows, knowledge/RAG solutions, intelligent decisioning, and AI-driven automation, with integration into platforms such as Zendesk, CRM systems, APIs, and Automation solutions. The ideal candidate will independently manage AI use cases from business problem identification through to continuous improvement in production.

- Enable AI Agents to interact with internal systems through APIs, automation tools, and other integration mechanisms.
- Design human-in-the-loop and exception-handling mechanisms for higher-risk scenarios.

LLM & Applied AI Development
- Develop production-ready applications using commercial and/or open-source LLMs.
- Implement prompt engineering, structured outputs, function/tool calling, context management, and LLM orchestration.
- Design AI solutions for classification, summarization, information extraction, decision support, response generation, and workflow automation.
- Evaluate different models and approaches based on accuracy, latency, cost, security, and business requirements.
