Desirable

• We are seeking a Senior Backend Software Engineer to join our Measurement & Ads team
• This team is responsible for building and operating the core backend systems that support measurement, attribution, experimentation, and integrations across all of SoFi’s marketing channels
• In this role, you will tackle complex, data-intensive problems at scale, design reliable event pipelines, attribution systems, and APIs that connect ad platforms, internal analytics, and downstream consumers
• You’ll operate with a high degree of autonomy, owning meaningful backend components from design through production, while collaborating closely with Product, Marketing, Data, and other Engineering teams
• Design, build, and operate scalable backend services that power measurement, attribution, and ads enablement across SoFi’s paid channels
• Own complex, data-driven systems end-to-end, from architecture and implementation through deployment, monitoring, and long-term maintenance, particularly over high-volume event ingestion, identity mapping, and attribution data flows
• Build and evolve event ingestion pipelines, APIs, and data flows that integrate with external ad platforms, internal analytics, and experimentation frameworks, enabling near-real-time measurement and data activation use cases
• Contribute to the technical architecture and roadmap, help identify “big-rock” problems and propose durable, scalable solutions
• Ensure systems are highly available, observable, and correct, with strong guarantees around data quality and consistency, pipeline health, and attribution accuracy.
• Collaborate effectively to translate ads and measurement requirements into robust technical solutions
• Lead code and design reviews, set a high bar for backend quality and reliability, lead incident investigations, and drive improvements that reduce operational risk over time
• Mentor other engineers through technical guidance, thoughtful reviews, and shared ownership of outcomes
