Senior AI-First Full Stack Engineer
The MRJ team have partnered with a genuinely exciting technology business at the forefront of workforce innovation as they embark on the next phase of their AI journey.
This isn't a company trying to figure out what AI means. The vision, platform and investment are already in place. What comes next is where things get interesting.
We're looking for a highly capable Senior Full Stack Engineer who embraces an AI-first approach to software development. Someone who leverages tools like Claude, Cursor and modern LLMs to increase engineering velocity, accelerate experimentation and deliver high-quality products faster.
This role isn't about building foundation models or conducting academic AI research. It's about applying AI pragmatically to solve real business problems, create intelligent product experiences and help shape how software is built inside a modern technology business.
The Opportunity
You'll join a small, high-impact AI R&D team focused on evaluating, building and scaling AI capabilities across the wider platform.
You'll be given the freedom to experiment, prototype and challenge conventional approaches, helping identify where AI can genuinely create value for customers and the business. We're looking for the type of engineer whose ideas often start with: "I wonder if we could..."...and usually end with a working prototype a few hours later.

- Rapidly prototyping and validating new concepts using modern AI technologies
- Leveraging AI-assisted development tools such as Claude Code, Cursor and OpenAI models to maximise engineering productivity
- Designing and developing full-stack applications using .NET, Angular and Azure
- Creating prompt-driven workflows, agents and automations that interact with internal and external systems
- Identifying opportunities where AI can improve customer experiences, operational efficiency and product capability
