Software Engineer .NET

Concentrix Catalyst is the technology and digital transformation arm of Concentrix. We help organisations solve complex, real-world problems through engineering, human-centred design, and cloud-native delivery. Our teams work across government, healthcare, financial services, aviation, and telecommunications — embedded with clients from discovery through to production.

With offices across Melbourne, Sydney and Brisbane we run small, high-trust project teams where engineers, designers, and delivery leads work side by side. We’re partners with AWS, Microsoft, and Apple, and we’re proud of the reputation we’ve built through repeat work with clients like Transport for NSW, PTV, NSW Department of Communities and Justice, and others across the public and private sectors.

We’re looking for a mid-level .NET engineer who is equally comfortable on greenfield cloud-native builds and legacy modernisation engagements. You’ll work across the full delivery lifecycle — from shaping solutions with clients through to writing, testing, and shipping production code.

This is a client-facing role. You’ll collaborate with UX/UI designers, QA engineers, mobile developers, and delivery managers, and you’ll be part of the technical conversation from day one.

WHAT YOU’LL DO

Write clean, maintainable, and well-tested code across both modern and legacy .NET codebases

Contribute to the full delivery lifecycle — discovery, design, build, test, deploy, and support

Translate requirements into well-architected, pragmatic solutions

Design and consume RESTful APIs and microservices in cloud environments (AWS and/or Azure)

Work within cross-functional Agile teams alongside designers, QA, and mobile engineers

Participate in technical design reviews and architecture discussions

Maintain and improve CI/CD pipelines and code quality standards

Communicate clearly with clients and internal stakeholders — this is a visible, client-facing role

Continuously improve your knowledge and share it with the team

WHAT YOU’LL BRING

Essential

3+ years of commercial .NET development experience, including hands-on work across:

Modern .NET (8, 9, or 10) — APIs, background services, cloud-native patterns

.NET Framework — maintenance, migration, and modernisation of existing codebases

Commercial experience with cloud platforms — AWS or Azure

Experience building and consuming microservices and service-oriented architectures

Proficiency with React for front-end development

Strong grasp of SOLID principles, common design patterns, and software craftsmanship

Containerisation experience — Docker and Kubernetes (or equivalent orchestration)

Experience with CI/CD pipelines and writing testable, well-covered code

Delivery experience in Agile environments — Scrum and/or Kanban

Clear communicator — you listen well, explain things plainly, and work comfortably with clients

Desirable

Experience with CQRS and Event Sourcing patterns

Mobile development experience — React Native, iOS, or Android

Functional programming experience
