  • Strong understanding of marketing automation, data architecture, and integration patterns, with experience designing and implementing integrations between Marketing Cloud and CRM, Data 360, and external systems
  • Ability to clearly explain technical trade-offs and design decisions to both technical and non-technical stakeholders, combined with a proactive, curious mindset and comfort working in large, multi-disciplinary teams
