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. You'll be joining a highly visible team with significant investment, ambitious objectives and the opportunity to influence technical direction. 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. Desired Experience • 8-12+ years software engineering experience within complex enterprise technology environments. • Strong full-stack development capability with the ability to operate across multiple technologies and platforms. • Experience designing and delivering scalable distributed systems. • Proven understanding of software architecture and modern design principles. • Practical experience building, deploying or integrating AI, machine learning, generative AI or agent-based solutions. • Strong systems-thinking mindset with the ability to understand and optimise end-to-end business processes. • Experience leveraging AI-assisted development tools and modern engineering practices. • Ability to balance delivery speed with engineering quality and maintainability. • Strong communication skills with the confidence to engage with technical and non-technical stakeholders. • Python, Java or other modern programming languages. • Microservices and distributed architectures. • Architecture patterns including Domain-Driven Design (DDD), CQRS, Event-Driven Architecture and Clean Architecture. • Cloud-native development and scalable platform design. • API design, systems integration and interoperability. • Workflow automation and orchestration frameworks. • DevOps, CI/CD and software engineering best practices. • AI frameworks, LLMs, agentic workflows and intelligent automation platforms.
