We are seeking an experienced and forward-thinking Senior Software Engineer to play a key role in driving a large-scale AI and intelligent automation agenda within a complex technology environment.
We are looking for someone who combines strong full-stack development expertise with a genuine passion for AI, systems architecture, and business transformation. You will help identify, design, build, deploy and embed AI-powered solutions and agent-based workflows that deliver measurable business impact.
This opportunity is ideal for someone who wants to work in an AI-first environment where artificial intelligence is already being actively leveraged across engineering teams and business processes.

What You'll Be Doing:
- Design, build and deploy AI-powered applications, services and intelligent agents that automate and enhance business workflows.
- Partner with stakeholders to identify opportunities where AI can create efficiency, scalability and operational improvements.
- Drive end-to-end solution delivery across the full technology stack, from user-facing applications through to backend services and integrations.
- Contribute to technology strategy, systems design and architectural decision-making.
- Review and govern AI-generated code, ensuring quality, maintainability and long-term sustainability.
- Leverage modern AI-assisted engineering tools to accelerate delivery while maintaining robust engineering standards.
- Champion scalable, secure and interoperable technology solutions.
- Help shape the roadmap for AI adoption across the organisation and contribute to long-term innovation initiatives.
- Work within a fast-moving environment where experimentation, continuous learning and rapid execution are encouraged.
