🚀 Fullstack Engineer – .NET | Azure | React

📍 Full-time from our Varsity Lakes office


This is a Senior Engineering Role

This role is for a senior engineer, not a ticket-driven developer. We are a product company. Our core focus is development and delivery. We expect consistent momentum and visible progress — high-quality, production-ready code delivered every single day. If you are looking for a low-intensity environment or a purely task-based role, this will not be the right fit.


We are looking for someone who can design systems, own outcomes end-to-end, think commercially, and communicate professionally with stakeholders.


🎯 We want to Hear You - Not Just See Your Resume

A resume tells us where you’ve been — we want to know where you’re going, how you solve problems, and why this opportunity matters to you.


✅ We’re Looking for Someone Who

  • Has strong experience building RESTful APIs with ASP.NET Core in real-world, production environments
  • Is comfortable with end-to-end ownership: design → code → test → deploy → monitor → iterate
  • Has solid Azure experience and understands Ops & Infrastructure for the solutions they’ve built
  • Thrives in a high-autonomy environment: you take initiative, communicate clearly, and don’t wait for step-by-step instructions


đź§  How We Work

  • We’re translating 20+ years of FinTech experience from our domain experts into a new version of our product. Technically, we’re building a modular monolith delivered to our clients as independent, scalable deployment stamps using modern Azure cloud services.
  • We care about an engineering culture rooted in end-to-end ownership, business alignment, and real developer autonomy - you’re trusted to make decisions, not just follow tickets.


🛠 What You’ll Do

  • Lead AI-assisted development workflows, commanding modern AI coding tools to generate production code at speed while you focus on architecture, design decisions, and engineering review.
  • Collaborate directly with product stakeholders to turn their domain knowledge and product vision into well-designed backend features
  • Drive the design, implementation, and maintenance of RESTful APIs at scale for internal and external clients
  • Ensure all code is clean, functional, domain-driven code aligned with our modular monolith architecture and ISO 27001–friendly engineering practices
  • Manage and evolve our infrastructure and Ops stack using Azure DevOps pipelines
  • Help establish and refine our testing and performance strategy using xUnit, Testcontainers, and NBomber
  • Instrument services with OpenTelemetry and monitor them via Azure Monitor / Application Insights to keep our systems observable and reliable
  • Build and maintain user interfaces using React, delivering clean, responsive, and intuitive UI components that integrate with our backend APIs.


đź§° Our Tech Stack

  • Backend: C#, .NET 10, ASP.NET Core, Entity Framework Core
  • Frontend: React, TypeScript, HTML, CSS, REST API integration
  • Cloud & Infra (Azure): App Service, Functions, Container Apps, Static Web Apps, Front Door, API Management, Blob Storage, Event Grid, Service Bus, SignalR Service, App Configuration, Key Vault, Pulumi
  • Observability & Ops: OpenTelemetry, Azure Monitor, Application Insights, Azure DevOps, Git
  • Quality & Testing: SonarQube, xUnit, Testcontainers, NBomber, FluentValidation
  • Patterns & Libraries: DDD, CSharpFunctionalExtensions


đź’ˇ Why Join Us

  • Work directly with product stakeholders on a modern FinTech platform
  • Join a values-led company focused on long-term partnerships
  • Build meaningful solutions - not just close tickets in a queue
  • Be trusted to own your work and grow with the role as the product evolves


✉️ How to Apply - READ CAREFULLY

Instead of just sending a CV, include a short write-up (bullet points are fine):

  • A project you’ve delivered and your role
  • The tech and patterns you used (and why you chose them)
  • How your work delivered value - for the business, users, or team
  • Why this role and our values resonate with you - especially around ownership, autonomy, and building real product


You can attach your resume and/or GitHub/LinkedIn, but the write-up is what we’ll read first.


This is an office-based role located in Varsity Lakes on the Gold Coast.
