• Develop reusable connectors, DataWeave transformations, and scalable integration components

• Support implementation of a headless CMS (Contentful) and CDP by exposing, orchestrating, and transforming data

• Diagnose, troubleshoot, and recommend solutions for complex integration challenges across distributed environments

• Apply performance, reliability, observability, and security best practices across all MuleSoft services

• Collaborate closely with experience designers, architects, and data engineers to deliver cohesive, production-ready features

• Participate in technical design reviews, architectural discussions, and iterative product planning

• Build cloud-native, scalable services that support real-time, personalized guest experiences

• Implement testing strategies (unit, integration, functional) to maintain high quality and minimize regressions

• Contribute to continuous improvement, operational readiness, and incident resolution

• Strong analytical and problem-solving skills with the ability to evaluate alternative integration approaches

Nice to Have

• Experience with Vercel or similar serverless deployment environments

• Background in hospitality, entertainment, or high-volume customer experience systems

• Familiarity with real-time or event-driven patterns (Kafka, Webhooks, etc.)

• Experience with observability and monitoring tools for distributed systems

• Prior work on large-scale, high-visibility digital transformation programs

• Experience using AI-assisted development tools such as Vibes, GitHub Copilot, Claude Code, or OpenAI Codex

• Familiarity with modern development environments such as VS Code, Cursor, or Zed

Who You’ll Work With

You’ll collaborate closely with:

• Experience Designers

• Solution Architects

• Data Engineers

These partnerships ensure every feature is thoughtful, scalable, and aligned to both user needs and technical realities.

What Helps You Thrive Here
