Principal Designer

Help Make the World More Hospitable

The hospitality industry is uniquely human, and it deserves technology that's just as inspiring as the people behind it. At Mews, we're transforming the industry with a platform that helps hotels run smarter, move faster and create better guest experiences.

About the Role

The design choices made at the system level right now will shape what every product tribe at Mews can build for years. This role owns that layer: the design system, cross-tribe agents and skills, research engines, and the architectural standards that make coherent design possible at scale. Most Principal Designers sit inside a tribe and own a product surface — this one sits above all of them and owns the foundation they run on.

What You Would Do

• Build and maintain the design foundation across the division: the design system, cross-tribe agents and skills, research and discovery engines, design architecture, guidelines, and standards.
• Hold the multi-year view — write clearly about what design across the division will need that it doesn't yet have.
• Build AI-powered agents, skills, and tooling that encode design judgment into reusable systems.
• Work with Staff Designers so that tribe-level design substrates compose into a coherent whole.
• Partner with the VP on the most complex cross-tribe design problems.
• Contribute craft feedback and calibration input into Director and Staff Designer performance reviews.

AI Fluency

You've shipped AI-powered systems, building the agentic design tooling and AI skills that the entire design division runs on — agents that encode judgment, research engines that scale discovery.

What You Would Bring

• A body of shipped, high-quality design work and demonstrable taste, senior enough to be credible across multiple tribes.
• Multi-year thinking and the ability to encode it into systems and agents that outlast any single initiative.
• Genuine satisfaction in cross-tribe substrate work.

What's in It for You

Unlimited paid holiday, company share program, paid parental leave, annual learning budget, flexible hybrid working, and home office setup budget.
