Senior Software Engineer, Backend (Lake Analytics Platform)

About the Role

Affirm is reinventing credit to make it more honest and friendly. The Data and Storage Services team builds and operates Affirm's data infrastructure across OLTP and OLAP systems—including online checkout databases, batch orchestration, streaming infrastructure, and analytics platforms. As a Senior Backend Engineer on the Lake Analytics Platform team, you'll design and extend platform systems that enable engineers across the company to work with data at scale, focusing on reliability, self-service capabilities, and the roadmap toward agentic data tooling.

Responsibilities

• Design and implement platform features for automated provisioning, deploy pipelines, access control, service lifecycle management, and reliability tooling that engineers across Affirm rely on to build and operate data applications at scale.
• Build and maintain integrations between the platform and internal systems—CI/CD pipelines, identity and secrets management, external APIs, and event-driven hooks—ensuring application teams have secure, reliable, and self-service access.
• Design and operate secure data access patterns, including role-based access control (RBAC), managed-access schemas, dynamic data masking, secure views, and cross-database grants that maintain data governance without creating operational bottlenecks.
• Identify recurring operational patterns—access provisioning, pipeline failures, service health management, secrets management—and build automation and tooling to convert manual workflows into self-service capabilities for platform users.
• Build telemetry, alerting, and log infrastructure so platform teams and application owners can independently diagnose and resolve issues; establish runbooks and operational patterns that reduce incident blast radius and recovery time.
• Participate in on-call coverage, triage production incidents across platform services and dependent applications, and execute platform-level maintenance with operational care.
