Creatives who want to design it better. Communicators to win business. Collaborators to build it. Data pros who turn numbers into insights. Product builders who turn ideas into innovations. Anyone eager to be on a team that doesn't stop to ask what's next, because they're already building it. Mission This role exists to build and maintain the data infrastructure that powers dynamic, catalogue-driven advertising at scale. The CDA team owns the feeds and data ingestion layer — the systems that transform large-scale product catalogues and transaction data from retailers into the building blocks of high-performing ads across Facebook, Instagram, Snapchat, Pinterest, and beyond. Without this engineer, the platform doesn't scale, the data doesn't flow, and advertisers can't deliver. This is a hybrid role requiring onsite presence 4 days per week. Outcomes — What Success Looks Like in 6–12 Months Owns features end-to-end: Has shipped multiple features independently — from technical design through deployment and monitoring — with minimal oversight and strong production quality. Meaningfully improves data ingestion reliability: Identifies and resolves bottlenecks or failure points in the feeds/ingestion pipeline, measurably improving uptime, latency, or data accuracy for downstream teams. Earns trust as a platform thinker: Demonstrates clear API boundary design and system decisions that balance the needs of consuming teams with long-term platform health — recognized by peers and leads. Elevates team code quality: Consistently delivers thorough code reviews that catch real issues, improve maintainability, and raise the bar on testing and observability practices across the team. Grows as an AI-native engineer: Has integrated AI-assisted development tools meaningfully into their workflow and can articulate specific ways those tools have expanded the scope or quality of what they deliver.
