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.
So are YOU our next Senior Software Engineer? You are if you…
Senior-level experience building backend services in .NET.
Hands-on experience with Domain-Driven Design (DDD) and a solid grasp of its core patterns and strategic design.
Production experience with Event Sourcing.
Production experience with CQRS.
Experience designing and building distributed, microservices-based systems.
Experience with cloud infrastructure, ideally GCP.
Experience with both asynchronous (Pub/Sub-style messaging) and synchronous (HTTP/REST) communication patterns.
Frontend development experience with Angular.
A track record of writing automated tests and treating quality as part of delivery.
Real production support experience — you've been on the hook for the systems you've shipped.
A product mindset: you care about the user and business outcome, ask "why," and help shape what gets built.
