Staff Backend Engineer : Digital Credit Platform (AI-Augmented Engineering)
Domain: Fintech, Lending, or Credit Systems
About the team / Role
As a Staff SOFTWARE Engineer, you will be the primary architect and execution lead for the transformation of our Digital Credit Application. We are pivoting from a legacy monolith to a high-performance, pluggable API ecosystem. Your mission is to decouple core adjudication logic, enable rapid A/B testing of the customer journey, and lay the technical foundation for future AI-driven chat and automated decisioning experiences.
This is a high-impact role designed for a true "builder" who thrives on the duality of supporting a live production environment while aggressively migrating mission-critical services to a modern, microservices-based backbone.
The AI Edge: We are a forward-thinking engineering org. You are expected to be an expert in leveraging AI Software Development Lifecycle (AI DLC) tools (e.g., GitHub Copilot, Cursor, Amazon Q, LLM-based code gen and architecture agents) to accelerate migration, write bulletproof tests,
and automate documentation.
How you'll make an impact
Architectural Migration & Strategy
Strangler Fig Migration: Lead the decoupling of core credit application logic out of the legacy monolith and into a scalable, cloud-native Java/Spring Boot microservices workplace.
Migration with Zero Downtime: Design and execute high-volume traffic migration strategies from legacy systems to new stacks seamlessly without disrupting live customers.
Pluggable Adjudication & API Ecosystem
Modular Architecture: Design and implement a modular adjudication layer allowing the business to swap or update credit rules and third-party data providers without impacting core application flows.
API-First Design: Build and maintain robust, versioned REST/gRPC APIs that support a multi-channel experience (Mobile, Web, and future AI Chat interfaces).
A/B Strategy Enablement: Engineer backend infrastructure for dynamic routing and
