Key clients include Mastercard, American Express, Cathay Pacific, British Airways, LATAM, Flying Blue, Accor, EasyJet, HSBC, Chase, HDFC.

Our mission is focused on doing good beyond profit, which for us means we seek out opportunities for our people to share in our success and that we give back to the communities and people within which we work.

Never short of ambition, the success of our business is delivered through the diverse and talented team of over 2,200 global colleagues. We are now looking for a visionary Principal Engineer to help define the next generation of our platform.

We're now growing our team in Poland and want to be upfront about how this role is structured. As we don't yet have a legal entity in Poland, we work with an Employer of Record (EOR) or umbrella company to onboard talent in the region. This means the role is offered on a 2 year fixed term basis via an international contractor agreement — and is fully remote.

As we continue to evolve our web platforms and digital capabilities, we’re looking for a talented Web Engineer to help shape the future of our technology ecosystem.

This is more than just a React role. You’ll be joining a collaborative engineering environment where innovation, scalability, accessibility, and customer experience sit at the heart of everything we build.
