Staff Backend Engineer - Ads Experiences

Meet Fetch Engineering At Fetch, engineering is driven by curiosity, ownership, and a bias toward action. We operate in complex problem spaces where the right answer is not always clear, and success depends on adaptability, critical thinking, and informed decision-making. Our engineers are comfortable navigating ambiguity, understanding tradeoffs, gathering context, and turning uncertainty into progress while maintaining high technical standards. Engineers at Fetch take pride in building reliable, scalable systems that serve millions of users. You will contribute directly to the codebase, collaborate closely with cross-functional partners, and help shape best practices that elevate the quality of our work. We foster a culture of mentorship and collaboration, where engineers grow by learning from one another and holding a high bar for quality, reliability, and impact. About the Role: Fetch's Ads Experiences organization builds the consumer-facing earning experiences that sit at the center of our growth and monetization strategy. These platforms power rewarded gaming and play experiences, shopping rewards, card-linked earning, and the offer infrastructure that connects consumers, brands, and advertisers across Fetch. We're hiring a Staff Backend Engineer to help design and evolve the systems that power Fetch's rewarded gaming, shopping rewards, card-linked earning, and offer platform experiences. You'll build backend architecture that enables earning attribution, offer eligibility, reward fulfillment, partner integrations, and personalized consumer experiences at scale. These platforms directly impact user engagement, retention, and monetization, requiring systems that are reliable, observable, and capable of processing high volumes of transactions and events with accuracy and consistency. This is a high-impact role at the intersection of distributed systems, data, and consumer product experiences, where scalability, reliability, and operational excellence are non-negotiable. This is a full-time role that can be held from one of our US offices or remotely in the United States. What you’ll do at Fetch (Role Responsibilities): Design and scale core services that power rewarded gaming, shopping rewards, card-linked earning, and offer delivery experiences, building highly available systems that support millions of users and drive measurable business outcomes. Build and evolve backend services that determine offer eligibility, earning qualification, reward attribution, and fulfillment outcomes using real-time transactional, behavioral, and partner-provided signals. Develop consumer-facing and platform APIs that support offer discovery, reward experiences, earning flows, partner integrations, and internal tooling across Fetch's Ads Experiences ecosystem. Design reliable event-driven systems and data flows that process high volumes of transactions, installs, purchases, and earning events while maintaining accuracy, consistency, and operational efficiency. Build platform capabilities that enable experimentation, feature rollouts, configuration-driven behavior, and rapid product iteration while maintaining system integrity and reliability. Develop observability, monitoring, and operational tooling for revenue-generating systems by instrumenting tracing, structured logging, alerting, and metrics that provide visibility into platform health, performance, earning attribution, fulfillment accuracy, and system behavior. Partner across Product, Data, Analytics, and Engineering to define platform capabilities, evaluate technical tradeoffs, and ensure technical investments align with business objectives and long-term platform strategy. Lead architectural decisions across multiple services and domains, balancing scalability, reliability, maintainability, and development velocity as Ads Experiences continues to grow. Improve engineering leverage by identifying opportunities for platformization, reusable services, and shared infrastructure that accelerate development across multiple teams and product areas. Raise the bar on backend architecture, operational excellence, and engineering standards, helping teams build systems that are scalable, observable, resilient, and easy to evolve over time. In your Toolbox (Minimum Requirements): 12+ years of experience designing, building, and operating backend systems that support critical, user-facing products at scale. Demonstrated ownership of backend architecture for complex, distributed systems, including long-term evolution, scalability planning, failure modes, and operational maturity. Deep expertise in API design and service boundaries for systems that process transactions, business rules, eligibility decisions, attribution, or other high-volume workflows. Proven experience designing and operating event-driven architectures and data-intensive systems that integrate multiple internal and external data sources. Strong track record of building highly reliable systems with comprehensive observability, including monitoring, tracing, alerting, performance analysis, and incident response practices. Experience making architectural decisions involving scalability, reliability, latency, operational cost, and developer productivity tradeoffs. Ability to independently translate ambiguous product and business requirements into robust backend designs with clear technical and operational tradeoffs. Demonstrated influence beyond direct ownership, including mentoring senior engineers and setting engineering standards for reliability, maintainability, and system design excellence. Nice to haves/Bonus Points (Preferred Requirements): Direct experience building monetization, rewards, loyalty, marketplace, advertising, gaming, or other revenue-generating consumer platforms. Experience designing systems that support offer delivery, earning attribution, reward fulfillment, campaign execution, recommendation workflows, or partner integrations at scale. Experience defining and operating high-throughput transactional systems where accuracy, consistency, and reliability are critical to the user experience and business outcomes. Familiarity with experimentation platforms, feature flagging systems, and measurement frameworks used to evaluate and optimize consumer experiences. Experience designing backend systems that support personalization, ranking, targeting, or other data-driven product capabilities. Experience operating event-driven architectures and large-scale data processing systems used for attribution, eligibility, or consumer engagement workflows. Familiarity with consumer mobile platforms and the backend infrastructure that powers iOS and Android experiences. Prior Staff or Principal-level experience driving architectural direction across teams, platforms, or product domains.
