Staff Engineer - Fintech

About the Role

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.

Responsibilities

• Own the tribe’s engineering agents, skills and context, and encode architectural standards, review logic and quality gates into them so the standard is met by default.
• Build an AI first responder for customer tickets about payment issues, with clear rules for when it answers and when it hands over to a person.
• Stay hands-on for the hardest technical problems: migrations, system-wide refactors and long-lived architecture decisions across PSP integrations.
• Keep Payment Interfaces integrations coherent as PSPs and regional requirements change, collaborating with builders who own their own work.
• Coach builders and fix off-standard outcomes at the cause, so the lesson sticks.

Requirements

• Hands-on experience integrating with payment service providers or payment processors.
• Deep engineering craft and architectural judgment, including a sense of what is worth codifying and what is a one-off.
• AI Fluency Level 4 or equivalent hands-on experience: you have built agents, skills, evaluations or tooling that other engineers use, and you can explain where human oversight stays non-negotiable.
• A systems mindset that turns hard-won knowledge into reusable architecture and tooling rather than documentation.
• Comfort with influence as your main way of getting things done, working with builders, product managers, principals and senior leaders without anyone reporting to you.

Nice to Have

• Experience in hospitality, travel or another operationally complex B2B SaaS environment.
• Experience publishing or speaking externally about your work.
• A track record of coaching other engineers and multiplying their effectiveness.
