Software Developer
Summary
Intermediate .NET Developer building backend services and AI agents using C#, .NET, and SQL Server. You will connect an in-house language model to business data, develop predictive features, and use AI coding assistants within an agile team to automate workflows for hundreds of internal users.
The Company
Our client is an established New Zealand business with a growing presence in Australia, and hundreds of internal users who rely on software their own team builds. They run their own AI foundation, including a proprietary language model, and treat AI as a core business tool rather than an experiment. They pay for proper tooling and give people room to try things. Developers are backed by an active AI user group, overseas hackathons and a culture of growing capability from within.
The Role
We are looking for an Intermediate .NET Developer to join a close-knit team. You will start on well-scoped pieces of real production work and take on more as you prove yourself, with senior developers close by to review, challenge and guide. The work is backend-focused, building the services and agents that sit behind tools used across the business every day.
What You'll Be Doing
- Building backend services and APIs in C# and .NET that power AI agents, conversational assistants and automated workflows
- Connecting an in-house language model to customer, pricing and transaction data
- Helping deliver features that predict customer behaviour and remove repetitive manual work
- Using AI coding assistants daily to move faster, then checking and testing what they produce before it goes anywhere near production
- Having your code reviewed by senior developers, learning from it, and reviewing the work of others
- Working with analysts in an agile delivery stream to turn rough ideas into working software
- Taking part in the AI user group and bringing new tools and techniques back to the team
Skills and Experience We're Looking For
- 2-4 years' commercial experience in C# and .NET
- Comfortable building and consuming REST APIs, with working SQL Server knowledge
- Exposure to cloud platforms
- Real experience using AI coding tools, and curiosity about LLM APIs and agents
- Solid fundamentals in object-oriented design, testing, source control and agile delivery
- An ambitious, quick-learning attitude and a habit of asking good questions
- Able to talk through your own code and comfortable writing some live in a technical interview
