What Makes You a Strong Fit

• You’re an engineer who enjoys building and shipping, not just planning architecture
• You understand both software engineering and the realities of performance marketing
• You know how marketing data moves between ad platforms, backend systems, and CRMs
• You can troubleshoot attribution and tracking problems
• You’re comfortable integrating APIs and automating complex workflows
• You actively use AI to improve engineering speed and business processes
• You can work directly with non-technical teams such as media buyers and marketers
• You move quickly without sacrificing reliability

What a Typical Day Looks Like

You might start by reviewing tracking data and investigating an attribution discrepancy between Meta Ads and the CRM.

Later, you could build a new Next.js dashboard for media buyers, implement a Python service that scores incoming leads using AI, or create a webhook integration that sends CRM conversion outcomes back through Meta CAPI.

You’ll work closely with media buyers and leadership to identify bottlenecks, build solutions, deploy them, and iterate based on real campaign performance.

In short: you build the technology connecting advertising, CRM, AI, data, and operations - helping the agency run faster and make better marketing decisions.

Key Metrics for Success

• Internal tools actively adopted by media buyers and operators
• Accurate Meta Pixel/CAPI tracking and attribution
• Reliable CRM and advertising-platform data synchronization
• Reduction in manual marketing and operational workflows
• Faster campaign reporting and execution
• Improved lead tracking and conversion visibility
• Successful deployment of AI-powered workflows
• Reliability and scalability of production systems

Why This Role Stands Out

• Build technology directly tied to marketing performance and revenue
• Work across software engineering + AI + ad tech
• High ownership over internal products and systems
• Direct collaboration with leadership and performance marketing teams
• Opportunity to build AI systems used in real production workflows
• Work with marketing operations supporting 150+ home service businesses
• Fully remote environment with significant autonomy
