About the Company

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. You'll work with smart, curious people who care deeply about what they do. You'll have autonomy and the trust to make good decisions and move quickly. And you'll enjoy a real sense of purpose as you see the impact of what we're building. If you're motivated by ownership, curiosity and meaningful impact, and are driven to deliver consistent high performance, you'll feel at home here.

About the Role

As a Product Builder in the Acquiring domain, you'll take end-to-end ownership of initiatives: framing the problem in a short design document, prototyping a solution, demoing to peers and stakeholders, shipping to production, and staying close enough to see whether it actually helped. The surface area is broad: payment acceptance (authorization, capture, refunds, disputes), the payment-facilitator layer (sub-merchant data, identifiers, card scheme compliance), acceptance expansion across markets, and reporting into our ledger. You'll work in a small domain team with no management layer in between. The tribe's Product Manager and Staff Engineer help with direction where relevant, but you won't be waiting for it. You'll set scope, run experiments, make calls, and run what you build. Hospitality payments are at an inflection point. Hotels want payments that are embedded, transparent, and cheaper to run, and the gap between what exists and what's possible is real. Product Builders in Fintech close that gap.

Responsibilities

  • ● Take end-to-end ownership of product initiatives in Acquiring: defining the problem, prototyping the solution, shipping to production, and iterating based on real customer feedback.
  • ● Design and implement the systems that power card and alternative payment acceptance, the payment-facilitator layer, and reporting to ledger.
  • ● Leverage AI to ship faster, set the standard for how it is used in the development process across the tribe, and build reusable approaches that accelerate other domains.
  • ● Establish reusable patterns and frameworks that accelerate the work of other Product Builders, and coach those who want to develop in this direction.

Requirements

  • ● AI Fluency Level 3: In this role, AI is a core part of how you build, not an add-on. You have redesigned how you or your team works with tools like Claude, Cursor or agent frameworks, and you have built approaches that other engineers now follow. You also question what the AI gives you: you check the code and the payment logic it produces and know when it is wrong, which matters most in a domain where correct
