FLEX, Senior Director, Engineering and Architecture – Centralized Messaging and Conversational Intelligence
Marriott InternationalAbout the role
This is a temporary position.
We are looking for a Senior Director of Engineering & Architecture to lead the solution design and development of a centralized messaging platform that orchestrates guest communications across a wide range of channels. This platform will act as a central abstraction layer that integrates with:
- Internal tools (e.g., call centers, hotel front desks)
- Owned guest channels (e.g., web chat, mobile app chat)
- External messaging platforms (e.g., WhatsApp, SMS, iMessage)
The platform will incorporate an AI-powered orchestration layer to enable intelligent message routing, response generation, and conversational workflows using machine learning models (MML) trained on domain-specific content.
This role is ideal for a hands-on technical leader who can architect for scale, build a global team, and partner with product, operations, and guest experience teams to bring modern, unified messaging experiences to life.
Key Responsibilities
Platform Architecture & Solution Design
- Architect a central abstraction layer that serves as the single integration point for messaging across all internal and external channels.
- Design and maintain a modular system that can support omnichannel communication with consistent behavior, security, and data handling.
- Ensure scalability, reliability, and adaptability to integrate new endpoints or message formats quickly.
AI & Conversational Intelligence
- Lead the integration of an AI/ML layer that leverages existing MML models to:
- Automatically classify and route messages
- Generate intelligent, context-aware responses
- Escalate and hand off conversations to humans when needed
- Partner with data science teams to refine models and optimize routing logic based on behavioral signals, context, and guest profile data.
Channel Integration
- Oversee integrations with a wide range of messaging endpoints, including:
- Call centers and front desk associate tools
- Web and mobile app chats
- 3rd-party messaging platforms (e.g., WhatsApp, SMS, iMessage)
- Support consistent user experiences, compliance, and personalization across all channels.
Engineering & Team Leadership
- Build and lead a global engineering team focused on API development, orchestration services, and channel integration.
- Establish engineering excellence and delivery practices for scalable microservices, observability, and continuous improvement.
- Collaborate cross-functionally with platform teams, product managers, UX, guest services, and AI/ML teams.
Governance, Compliance & Personalization
- Ensure all communications comply with local data privacy, opt-in/opt-out, and regulatory requirements.
- Support context-aware personalization using data from guest journeys, CRM systems, and operational touchpoints.
Qualifications
- 15+ years in software engineering or architecture with experience designing and delivering complex, distributed systems
- 5+ years of leadership in omnichannel messaging, conversational AI, or digital customer experience platforms
- Deep experience in building API-based integration layers, messaging middleware, and intelligent routing systems
- Proven ability to integrate and manage 3rd-party messaging platforms (e.g., Twilio, Meta/WhatsApp, Apple Business Chat)
- Hands-on understanding of AI/ML models used for message classification, response generation, or routing
- Familiarity with cloud-native architecture, message queueing, microservices, and event-driven systems
Preferred Qualifications
- Background in customer service, hospitality, or platform-as-a-service
- Experience delivering automated conversational flows across multiple digital surfaces
- Familiarity with LLMs, MML pipelines, and AI models for conversational intelligence
- Experience working with tools like Apple Business Chat,Twilio Flex, LivePerson, or Intercom is a plus
