About the Role
At Pavago, one of our clients—a fast-growing marketing agency serving 150+ home service businesses—is hiring a Full Stack Engineer to build and scale the technology powering its marketing, lead generation, tracking, and revenue operations.
This is a hands-on builder role, not a strategy-only engineering position.

•
Meta Pixel & Conversion API (CAPI)
•
AI-powered marketing workflows
•
CRM integrations and automation
•
Internal dashboards and operational tools
You’ll work directly with leadership, media buyers, and operators to turn real business problems into production-ready systems that improve campaign performance, lead conversion, and operational efficiency.
If you’re a strong full-stack engineer who understands both software engineering and performance marketing technology, this role is a strong fit.
