We're looking for our next Senior Software Engineer. Could It Be You?We're building the next-generation Loan Origination System for Questbank's Secured Lending business - a distributed, event-sourced platform that powers how we take a loan from application to funding. It's a microservices architecture on Google Cloud Platform (GCP), designed from the ground up with Domain-Driven Design, Event Sourcing, and CQRS.
As a Senior Software Engineer on this team, you'll design and build core services end to end, from domain modelling through to production support. You'll work across a .NET backend and an Angular frontend, and you'll own the quality of what you ship - including the automated tests that keep us moving fast. We're looking for someone who thinks like an owner: someone who understands the business problem behind the ticket and helps shape the product, not just implement it.
Need more details? Keep reading...- Design and build microservices for the Loan Origination System using Domain-Driven Design as the foundation for how we model the business.
- Implement and evolve an Event-Sourced system with CQRS - designing aggregates, events, projections, and read models.
- Build and integrate services across two communication patterns: asynchronous messaging via Pub/Sub and synchronous HTTP.
- Develop backend services in .NET and contribute to the Angular frontend.
- Deploy and operate services on GCP.
- Write and maintain automated tests across the stack, including end-to-end coverage.
- Provide production support for the systems you build - diagnosing issues, improving observability, and keeping services healthy.
- Partner with product and business stakeholders to translate lending needs into well-designed software, bringing a product mindset to technical decisions.
