At loveholidays, we trailblaze together. We’re on a mission to open the world to everyone, giving our customers unlimited choice, unmatched ease and unmissable value for their next getaway. Our team is the driving force behind our role as our customers’ personal holiday expert - the smart way to get away.

Technology at loveholidays underpins our vision to become the global leader in packaged holidays. We drive cutting-edge innovation and technical excellence to future-proof the business. Our systems process trillions of daily holiday offers, serving thousands of requests per second. Join us to create impact for our future in an exciting new chapter, owning your success and contributing to shared goals.

You will be joining our growing Conversational AI team, which sits at the heart of our ambition to deliver intelligent, seamless customer experiences at scale. The team builds and maintains the AI-powered agents and tooling that power interactions across our contact centre and digital channels – increasingly leveraging agentic architectures, large language models and the latest Google Cloud AI capabilities. This is a collaborative, fast-moving team where curiosity and a willingness to learn are valued as highly as technical skill.

Reporting to the Lead Conversational AI Engineer, you will play an important part in building and maintaining the conversational AI systems that help our customers find and manage their perfect getaway. As a level 1 engineer, you will be supported to develop your skills and grow your confidence, contributing to real solutions from day one whilst building a strong foundation in modern agentic AI technologies and engineering best practices.

Your day-to-day responsibilities include:

• Building and maintaining conversational AI agents using Google Dialogflow CX and Vertex AI Agent Builder, contributing to flows, fulfilment logic and agent configurations.
• Supporting the development of agentic workflows – learning how to design multi-step, tool-using agents that can reason and act across systems to resolve customer queries.
• Working with the Google Agent Development Kit (ADK) to assist in building, testing and iterating on agent capabilities under the guidance of more senior engineers.
• Analysing conversational data and real customer interaction patterns to understand how users engage with our agents, surfacing insights that inform improvements to the customer experience.
• Contributing to the testing and quality assurance of conversational flows and agentic pipelines, identifying and resolving errors or unexpected behaviour.
• Assisting in the analysis of conversational data and performance metrics to support continuous improvement of the user experience.
• Collaborating with Conversation Designers, product managers and engineers to ensure technical implementations match the intended design and business goals.
• Participating in team ceremonies including stand-ups, retrospectives and planning sessions, communicating your progress and raising blockers clearly.
• Staying curious about developments in agentic AI, LLMs and the broader conversational AI landscape, sharing learnings with the team through show and tells or internal channels.

We’re looking for someone who brings enthusiasm, a genuine interest in conversational and agentic AI technology, and the willingness to grow. You don’t need to have all the answers but you should be eager to find them.

Your skillset should include:

• Foundational understanding of conversational AI concepts – virtual agents (intents, entities, dialogue management, fulfillment) through to LLM-driven agentic approaches.
• Experience building virtual agents on conversational platforms (e.g. Google Dialogflow CX, Vertex AI Agent Builder, Amazon Lex, Rasa).
• Strong programming proficiency in Python or TypeScript or other programming language, backed by solid software engineering and infrastructure development practices.
• Experience designing LLM applications beyond basic APIs, including retrieval-augmented generation (RAG) pipelines, orchestration logic, and tool/agent workflows.
• Strong awareness of REST APIs and webhooks to effectively connect AI agents with backend systems and external tools.
• Familiarity with cloud deployment environments (preferably Google Cloud Platform) and CI/CD practices for AI workflows.

Desirable skills include:

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

The interview journey includes:

• TA screening – 30 mins
• 1st stage video interview with Lead Conversational AI Engineer – 1 hour
• Take-home engineering task
• Final stage with Director of Business IT & AI Operations and senior stakeholders – 1 hour
