Client Engagement Architect (Technology Advisory) in London

• Principal Engagement Architect
• London, UK

Principal Engagement Architects at Thoughtworks are the delivery and solution leaders for AI-native advisory engagements.

This role combines the responsibilities of an engagement manager, product leader, and systems thinker.

You will dictate how high-level strategy translates into working solutions and measurable outcomes.

You sit at the center of the engagement, connecting client intent, business outcomes, and execution reality to break down doors, get engagements started, and set up our delivery teams for success.

By balancing strong opinions with high intellectual curiosity and flexibility, you bring integrity to technology, driving innovation at the absolute edge of AI strategy.

• Job responsibilities

• You will structure and drive AI-native advisory engagements, breaking down complex, ambiguous problems into clear, actionable components across team members, AI agents, and client stakeholders.
• You will orchestrate AI-native delivery, designing how AI is used across analysis, scenario modeling, workflow generation, and documentation while effectively managing output quality.
• You will ensure quality and coherence across the engagement, reviewing outputs for logical consistency, business relevance, and technical feasibility to build a cohesive narrative.
• You will interface directly with client delivery leadership (such as CTOs, CIOs, and program leads), translating advisory recommendations into practical execution paths and navigating tradeoffs in real time.
• You will proactively manage risk and execution reality, identifying technical, organizational, or commercial delivery risks early and adjusting the approach to maintain progress.
• You will build reusable delivery patterns, capturing and refining repeatable workflows, engagement models, and decision frameworks to expand our library of AI-native advisory assets.
