About the role

A performance marketing team needs an experienced full-stack developer and technical architect to scope, build and manage a custom funnel analytics dashboard. It combines data from Meta Ads, Shopify, attribution platforms and individual sales funnels so the team can understand funnel performance, spot opportunities and make better marketing decisions.

• Integrate Meta Ads, Shopify, Hyros, Google Ads and other data sources, build reliable data pipelines, connect ad-level performance to conversions, and troubleshoot attribution discrepancies.
• Integrate AI models to identify underperforming stages and conversion drop-offs, generate insights and recommendations, and build natural-language reporting and automated summaries.
• Translate business requirements into technical specifications, recommend technologies and architectures, break work into tasks, and own development, QA, deployment, documentation and maintenance.
• Build and deploy custom applications on Railway or similar platforms, with scalable backends, APIs and databases.

Required profile
