Senior Software Engineer, Backend (Storage Services Engineering)

Affirm is reinventing credit to make it more honest and friendly, giving consumers the flexibility to buy now and pay later without any hidden fees or compounding interest.

At Affirm, data is fundamental to everything we do. Our data and storage solutions empower machine learning, artificial intelligence, cloud-based technologies, and other modern tools to create differential and scalable products. We prioritize building our own technology and investing in engineering talent, as we believe these are enduring competitive advantages that are difficult to replicate. Our expertise in sourcing, aggregating, protecting, and analyzing data has been what we believe to be a core competitive advantage of our platform since our founding. We use data to inform our analysis and decision-making, including risk assessment, in a way that empowers consumers and generates value for our merchants and funding sources.

Our mission is to provide trustworthy, intuitive, and cost-efficient solutions to secure, store, analyze, and transform data at exceptional scale. 

We are responsible for highly available, low latency, cost efficient compliant cloud based data storage, data processing, and analytics capabilities that enable all of Affirm’s customer-facing business critical websites/applications (e.g., checkout flows, merchant APIs, etc.) as well as back-office processes (e.g., Capital Engineering, Lending, etc.). To drive innovation at our scale, we need experienced engineers to build storage, data abstraction, streaming, transformation, analytics warehouse, replication, metadata platform, data exploration, governance framework.
