Conversion Tracking Specialist (GA4 / GTM / Meta CAPI)

We're a digital marketing agency serving 200+ restaurant clients, running Meta and Google Ads campaigns that feed into a proprietary attribution platform. We need an experienced specialist to own conversion tracking accuracy across a large, multi-account portfolio. The two conversion types you'll live in day to day are online food ordering and reservation bookings. This is ongoing work, not a one-time setup. You'll be the person we call when a client's numbers don't add up between platforms. The catch, and the reason we're hiring an expert rather than a generalist: our clients run their ordering and reservations through a wide mix of third-party platforms (Toast, Olo, ChowNow, DoorDash, Uber Eats, Grubhub, OpenTable, Resy, Tock, SevenRooms, and others). Each one has its own quirks for surfacing conversion data: some support native pixel firing, some require webhook-based server-side events, some only offer manual conversion import. There's no single tracking pattern that covers all of them. You'll need to be comfortable reading unfamiliar platform docs and figuring out the right approach each time, rather than relying on one memorized setup. Core responsibilities - GA4 property audits and configuration (custom events, conversions, audiences) - Google Tag Manager builds and repairs, including server-side containers where needed - Meta Pixel and Conversions API implementation with proper event deduplication - Diagnosing data quality issues: duplicate events, hashed email/IP mismatches, broken UTM structures, GA4-imported conversions that don't map to native platform actions - Cross-referencing third-party reporting data against platform-native data to find and explain discrepancies - Clear written documentation of what was broken and what you changed Requirements - Portfolio or work samples showing real GTM container builds and GA4 configurations (screenshots of a demo account are fine if client NDAs prevent live examples) - Demonstrated Meta CAPI experience, specifically deduplication and match quality work, not just "I added the pixel" - Comfortable working across dozens of accounts with varying levels of existing setup quality - Track record of learning new third-party platforms' tracking requirements independently (this comes up constantly here) - Strong async communication; we'll evaluate you partly on how clearly you write To be considered, start your proposal with the word "DEDUP" so we know you read the full post. Proposals that don't include this will not be reviewed.
