Staff Software Engineer- Growth Performance Marketing

About Pinterest:

Millions of people around the world come to our platform to find creative ideas, dream about new possibilities and plan for memories that will last a lifetime. At Pinterest, we’re on a mission to bring everyone the inspiration to create a life they love, and that starts with the people behind the product.

At Pinterest, AI isn't just a feature, it's a powerful partner that augments our creativity and amplifies our impact, and we’re looking for candidates who are excited to be a part of that.

What you'll do:

• Lead the technical roadmap for the performance marketing platform, defining the highest-impact investments across attribution, bidding, budget optimization, and campaign management
• Drive hands-on engineering across ad platform integrations, event pipelines, and production systems that deploy and measure marketing spend
• Design and evolve the measurement stack — attribution models, conversion signal collection, incrementality methodology, and privacy-resilient approaches as platform signals degrade
• Develop systems that automate and optimize bidding strategies and campaign experimentation at scale
• Drive cross-team technical initiatives with ads platform, data warehouse, and mobile teams — authoring design documents and building alignment across engineering orgs
• Own system reliability and operational health for spend-critical systems where downtime or bugs have direct financial impact
• Collaborate with marketing, data science, and product partners to identify growth opportunities and turn them into engineered solutions
• Mentor and develop engineers on the team, establishing technical best practices and raising the bar on system design
• Use AI to accelerate your own work—across exploration, drafting, analysis, and synthesis—while maintaining strong judgment, rigorous validation, and accountability for outcomes

What we're looking for:

• 7+ years of experience building and shipping backend systems, with hands-on experience supporting performance marketing
• Strong understanding of paid media platforms — Google Ads, Meta, TikTok, Snap, or similar — and the operational realities of integrating with their APIs at scale
• Deep understanding of attribution methodologies (last click, multi-touch, SKAN, probabilistic vs. deterministic), incrementality testing, and conversion optimization, with hands-on experience integrating mobile measurement partners (AppsFlyer, Adjust, Singular, or similar) across mobile clients and server-side APIs
• Experience with near real-time systems for bidding, budget optimization, and conversion event delivery — you understand the mechanics well enough to evolve existing systems and propose improvements
• Strong proficiency building and operating data pipelines
