Senior AI Application Software Engineer

At Booking.com, the CBO Office supports strategic and operational execution across the Chief Business Officer organisation, working across CBO departments and corporate functions. It brings together Business Operations, Change Management and Program Management to help the organisation prioritise, plan and govern major initiatives, enable business change and improve cross-functional delivery.

We are looking for a senior engineer to architect and develop AI-powered, agentic solutions across these three disciplines. Today, we have a collection of AI use cases and early solutions. The ambition is to evolve these into a coherent and scalable product ecosystem rather than a collection of disconnected AI applications, identifying common technical capabilities that can be reused across workflows while supporting the specific needs of each craft.

The engineer will help determine the right architecture for this ecosystem, including how agents, shared services, enterprise knowledge and data, and existing systems can progressively work together through agentic and multi-agent solutions.

We are looking for someone with a strong Software Engineering and solution architecture background, combined with hands-on experience developing GenAI and agentic applications. The person should have practical experience building agents and multi-agent workflows using platforms such as OpenAI/ChatGPT and Anthropic/Claude. Experience with MCP/tool integrations, RAG and grounding, context management, agent orchestration, APIs, evaluation, observability, guardrails and human-in-the-loop patterns is particularly relevant.

The engineer should be comfortable using AI-assisted development tools such as Codex and Claude Code and be able to take solutions from rapid prototypes to secure, reliable, maintainable and production-ready applications, rather than focusing only on experimentation.

The engineer will work closely with the Product Manager, programme lead, domain experts and Booking.com technology teams to translate product requirements into technical designs and working solutions. Experience with Project and Program Management workflows and enterprise productivity systems such as Jira, Confluence, Google Workspace and Slack is valuable.

This is primarily an AI application and architecture role, not an ML research role. The focus is on applying existing AI models and enterprise platforms to real business workflows rather than training foundation models.

KEY RESPONSIBILITIES

• Architect, build and productionise AI-powered applications, agents and multi-agent workflows.

  
  

• Translate business needs and product requirements into technical designs, prototypes and production-ready solutions.

  
  

• Identify and build reusable capabilities and common patterns across use cases and crafts.

  
  

• Design agent orchestration, retrieval/grounding, context and state management, tool calling and MCP-based integrations.

  
  

• Integrate solutions with relevant enterprise knowledge, data and systems through approved APIs and platforms.

  
  

• Implement appropriate evaluation, observability, guardrails, access controls and human-in-the-loop mechanisms.

  
  

• Own solutions end-to-end, including code quality, testing, security, deployment, monitoring, reliability and documentation.

  
  

• Rapidly prototype and evaluate technologies and architectures to validate feasibility and inform technical decisions.

  
  

• Work with Booking.com technology, platform and security teams to align with enterprise standards and avoid isolated solutions.

  
  

• Contribute to the technical roadmap and operating model required to maintain, support and scale the solutions.

  
  

• These responsibilities fit well with the Booking.com SWE framework's emphasis on end-to-end ownership, software-system design and architectural guidance, including evaluating architecture against business and technology requirements and designing for future evolution.
