Senior C#/.NET AI Engineer | LLM & AI Product Engineering in Sydney

Sydney (Hybrid) OR Remote Across Australia | $200,000-$250,000 + Super

I'm partnering exclusively with a global SaaS business to hire a Senior C#/.NET AI Engineer, someone who has successfully built and shipped LLM-powered products into production.

This is not an AI research role, and it's not about building demos or internal chatbots.

This is a software engineering role first, where you'll be designing and delivering customer-facing AI capabilities used by thousands of users across Australia, the UK and the US.

You'll work on initiatives including:

• AI-powered proposal generation
• Agentic workflows
• Intelligent workflow automation
• AI-assisted document and invoice generation

We're looking for someone with:

• Strong commercial experience building backend applications with C#/.NET
• Proven experience shipping production AI and LLM features to real customers
• Experience with technologies such as RAG, prompt engineering, structured outputs, tool and function calling, embeddings, vector search and modern AI engineering practices
• A passion for building high-quality software that solves real customer problems

What's on offer?

• Hybrid working in Sydney or remote anywhere across Australia
• Significant ownership over AI architecture and future product direction
• A modern engineering environment where AI is embedded into the software development lifecycle
• The opportunity to build AI products that deliver genuine value to customers
