Your Day-to-Day

  • Build and maintain conversational AI agents using Google Dialogflow CX and Vertex AI Agent Builder, contributing to flows, fulfilment logic and agent configurations.
  • Support the development of agentic workflows – design multi-step, tool-using agents that can reason and act across systems to resolve customer queries.
  • Work with the Google Agent Development Kit (ADK) to assist in building, testing and iterating on agent capabilities under guidance of senior engineers.
  • Analyse conversational data and real customer interaction patterns to understand how users engage with agents and surface insights to improve the experience.
  • Contribute to testing and quality assurance of conversational flows and agentic pipelines, identifying and resolving errors or unexpected behaviour.
  • Assist in analysing performance metrics to support continuous improvement of the user experience.
  • Collaborate with Conversation Designers, product managers and engineers to ensure technical implementations match design and business goals.
  • Participate in team ceremonies, including stand‑ups, retrospectives and planning sessions, communicating progress and raising blockers clearly.
  • Stay curious about developments in agentic AI, LLMs and the broader conversational AI landscape, sharing learnings with the team.

Your Skillset

We’re looking for someone who brings enthusiasm, a genuine interest in conversational and agentic AI technology, and the willingness to grow.

  • Conversational AI Core: foundational understanding of AI concepts – virtual agents, intents, entities, dialogue management, fulfillment and LLM‑driven agentic approaches.
  • Platform Exposure: experience building virtual agents on conversational platforms such as Google Dialogflow CX, Vertex AI Agent Builder, Amazon Lex or Rasa.
  • Software Engineering: strong programming proficiency in Python or TypeScript (or another language) with solid software engineering and infrastructure development practices.
  • Advanced LLM Orchestration: experience designing LLM applications beyond basic APIs, including RAG pipelines, orchestration logic and tool/agent workflows.
  • API Integration: awareness of REST APIs and webhooks to connect AI agents with backend systems and external tools.
  • Cloud & DevOps: familiarity with cloud deployment environments (preferably Google Cloud Platform) and CI/CD practices for AI workflows.

Desirable

  • Experience with the Google Agent Development Kit (ADK), LangChain or similar multi‑agent orchestration frameworks.
  • Familiarity with vector databases, hybrid search techniques and advanced chunking strategies for optimizing RAG systems.
  • Knowledge of or previous experience in the travel sector or fast‑paced B2C e‑commerce environments.
  • Familiarity with Git and working effectively within an agile team environment.
