Senior Full Stack .Net Developer

At carsales, we're all about making buying and selling a great experience. Since 1997, we've been evolving with the new economy to help people choose how they move — today and tomorrow.

When it comes to your career, we want to offer meaningful opportunities that empower you to make a lasting impact. But for that to happen, we strive to feel small — small enough to stay agile, learn across teams and connect authentically with each other.

With a vision to be the global leader in online vehicle marketplaces, we're transforming how people buy and sell across the world. We discover new ideas and bring them to life. We continue to grow and evolve, and we're not afraid to take bold steps to get there.

We embrace hybrid working, combining the flexibility of remote work with the energy and connection of in-person collaboration. We champion flexibility and offer a range of policies and leave options to support your wellbeing.

About the Retail team

In the Retail team, we build the services and experiences behind the buying and selling journey on one of Australia’s largest automotive marketplaces. We’re a team of product engineers: we start from the customer problem, and we own the solution from the interface through to the .NET services and AWS infrastructure behind it.

We’re looking for a senior full stack engineer who is just as comfortable in C#/.NET as in React and TypeScript, and who wants a real say in what we build, not just how we build it.

What you'll do

• Design, build and run features across the stack, from React and TypeScript interfaces to C#/.NET services on AWS
• Own what you ship in production, including reliability, observability, performance and responding when things break
• Work with product and design to understand customer problems and shape solutions, and push back with evidence when the trade-offs warrant it
• Drive projects from idea to delivery with minimal direction, making and documenting sound design decisions along the way
• Mentor junior engineers through pairing, code review and feedback
• Be involved in all aspects of software engineering practice, including breaking down work, code review, testing, source control and build processes
• Create and enhance team culture by sharing your knowledge and ideas, and by giving and receiving constructive feedback

What we're looking for

• Senior experience as a full stack engineer, with real depth in both C#/.NET services and React with TypeScript
• Experience designing, deploying and supporting production services on AWS, and the system design judgement that comes with it
• A product engineering mindset: you start from the customer problem and have helped shape products, not just deliver tickets
• You’re self-sufficient, drive your own work, and enjoy helping less experienced engineers grow
• A quality-first approach, including automated testing and CI/CD
• Inclusive and interpersonal attributes that connect you to our behaviours: we change the game, we own it, we step in, we are curious, and we don’t take ourselves too seriously

Nice to have

• Node.js in production
• Event-driven systems using queues and messaging, such as SQS, SNS or RabbitMQ
• Next.js or another modern React framework
• Experience on high-traffic consumer or e-commerce platforms
