We're partnering with a high-growth technology business looking for a Principal AI Productivity & Automation Architect to lead the development of AI-powered automation across the organisation.

This is a highly autonomous, hands-on role for someone who can identify where AI can create genuine business value and then build and deploy the systems to make it happen.

You’ll work closely with senior leadership to identify high-impact opportunities, design agentic workflows and deliver production-ready solutions that improve productivity and reduce manual work.

What you'll be doing:

• Identify and prioritise high-value AI and automation opportunities across the business.
• Design and build agentic workflows and automation systems end-to-end.
• Develop production-ready solutions using LLMs, APIs and orchestration tools.
• Translate business problems into practical, measurable AI solutions.
• Drive adoption through tooling, frameworks and enablement.
• Help shape the organisation's wider AI productivity strategy.
• Scale successful solutions across multiple teams and functions.

What we’re looking for:

• Proven experience building and deploying real-world automation systems.
• Strong hands-on engineering skills across LLMs, APIs and orchestration tooling.
• Experience designing and implementing agentic workflows.
• Strong Python, TypeScript or similar programming experience.
• Experience taking AI solutions from concept through to production.
• Ability to operate independently and lead cross-functional initiatives.
• Strong commercial/business understanding and the ability to identify where technology can deliver measurable value.

This is a chance to join at an early stage of an organisation-wide AI transformation, with significant autonomy to shape the roadmap, build the technology and influence how teams work.

You’ll be both the technical builder and strategic driver behind AI-powered productivity initiatives.
