Senior .NET Fullstack Developer

Are you a Senior Full Stack Developer who loves working across the front and back end of modern web applications?

Join a high-performing SaaS engineering team building the next generation of intelligent technology - used by millions of users globally.

This is a role where you’ll ship real features, learn fast, and be part of a major AI transformation in one of the most established digital platforms in the market.

What You’ll Do

You’ll work as part of a cross-functional engineering squad, contributing to new feature development, architecture improvements, and next-generation AI integrations.
Your work will include:

• Building and refining customer-facing features across React, JavaScript, HTML/CSS, and C#/.NET
• Developing robust backend systems to handle large-scale data processing
• Designing and implementing event-driven microservices and APIs
• Working with AWS, Terraform, and CI/CD pipelines to enhance reliability and performance
• Collaborating closely with product managers, designers, and engineers to deliver scalable, elegant solutions

You’ll get exposure to both front-end excellence and deep backend engineering - perfect for someone who enjoys variety and full ownership of their work.

Why You’ll Love This Environment

• Remote-first role – work from anywhere in Australia (Sydney preferred for sporadic office days)
• Work on a globally recognised SaaS product with hundreds of thousands of users
• Supportive and modern engineering culture that values learning, curiosity, and autonomy
• Opportunity to work with cutting-edge AI (LLMs, agentic systems) and AWS infrastructure
• A place where you’ll genuinely learn, grow and build something meaningful

This is a team that moves fast, embraces experimentation, and knows when to focus on polish and quality. You’ll work alongside talented developers who share ideas freely and collaborate to get great outcomes.

What You Bring
We’re looking for a developer who’s as comfortable in the browser as they are in the cloud. You’ll ideally have:

• 5+ years’ experience as a Full Stack Software Engineer / Developer
• Proficiency in React, JavaScript, HTML/CSS
• Strong back-end experience with C# / .NET (Core or Framework)
• Exposure to AWS services, APIs, and DevOps tools (Terraform, Docker, CI/CD)
• Curiosity around AI, automation, or LLM integrations
• A collaborative mindset and a love of continuous learning

You don’t need to know everything - this environment is built for people who want to grow fast and learn across the stack.

Salary: $150k - $175k + super
