Principal Software Engineer, Measurement & Attribution

About the Role Fetch is America's rewards app, and measurement sits at the center of everything we do. Every reward issued, advertiser invoice generated, partner payout processed, and trust signal delivered depends on our ability to accurately attribute real-world user activity across an increasingly complex ecosystem of partners, platforms, and channels. As Fetch expands across offers, shopping, dining, gaming, advertising, and credit card experiences, measurement has become both a foundational platform and a strategic differentiator. To support the next phase of Fetch's growth, we are investing in a unified measurement and attribution platform that enables consistent, scalable, and trustworthy event attribution across the entire ecosystem. This is a hands-on technical leadership role with influence across multiple organizations. You will guide architecture decisions, establish technical standards, mentor engineers, and help shape one of the company's most strategically important technical investments. This is a full-time role that can be held from one of our US offices or remotely in the United States. Role Responsibilities Define the Technical Strategy for Measurement & Attribution Own the long-term technical vision and multi-year roadmap for Fetch's measurement and attribution ecosystem. Drive architectural direction across event ingestion, identity resolution, attribution logic, reconciliation, reporting, and partner integrations. Build a Unified Attribution Platform Lead the development of a unified attribution spine that standardizes how Fetch measures user activity across offers, shopping, restaurants, gaming, impressions, and credit card experiences. Enable downstream consumers across Rewards, Billing, Finance, ML, Analytics, and Business Development to operate from a single source of truth. Architect Scalable Event Processing Systems Design and evolve distributed systems that process billions of events across Fetch's partner and consumer ecosystems. Ensure systems remain scalable, reliable, observable, and resilient as event volume, partner complexity, and business criticality continue to grow. Develop a Reusable Partner Integration Framework Create extensible frameworks and tooling that simplify onboarding and reconciliation across MMPs, DSPs, affiliate networks, Conversion APIs, card-linked offer providers, and direct merchant integrations. Reduce operational complexity and transform new partner onboarding from a lengthy engineering effort into a scalable platform capability. Advance First-Party Measurement Capabilities Help Fetch build direct measurement infrastructure that competes with external intermediaries through SDKs, server-to-server pipelines, deterministic and probabilistic matching, fraud controls, incrementality measurement, and privacy-conscious identity systems. Improve Trust, Reconciliation, and Auditability Establish systems and standards for discrepancy detection, dispute resolution, fraud detection, payout accuracy, and audit-grade lineage from raw event to recognized revenue. Ensure measurement systems support financial reporting requirements and regulatory compliance. Drive Cross-Functional Technical Alignment Partner closely with Product, Ads, Growth, Data, Finance, Legal, and Business Development teams to align technical systems with business strategy, partner requirements, privacy considerations, and revenue goals. Influence architectural direction across multiple engineering organizations. Mentor and Elevate Engineering Teams Provide technical mentorship to senior engineers and emerging technical leaders. Raise the engineering bar across system design, operational excellence, reliability, and architectural thinking. Accelerate Engineering Productivity Champion development practices and tooling that improve engineering velocity and system quality, including AI-assisted development tools such as GitHub Copilot or Claude Code, improved observability, streamlined CI/CD workflows, and stronger developer experience. Model Technical Excellence Lead by example through strong engineering judgment, pragmatic architecture decisions, and clear technical communication. Promote a culture of ownership, accountability, clarity, and long-term thinking in a domain where correctness and trust are critical.
