Senior Java Developer

Senior level • Full-time • On-site • Cluj-Napoca

Job Summary

We are helping to make cities better places to live, work and visit, by enabling seamless, frictionless journeys on public transport systems. We are a technology company, developing a SaaS-based fare collection and ticketing platform that allows commuters to buy and present tickets for public transport on their mobile phones or simply by tapping a bank card to travel. With deployments to over 60 transit agencies across 4 continents, our team has been delivering innovation to millions of riders of public transportation for over ten years.

Proving ourselves as true innovators and category leaders, we launched a ticketing SDK - a first for public transit - allowing urban mobility providers like ride-hailing (Uber), journey planners (Transit), and bike and ride-sharing services, to integrate our market-leading ticketing platform into their applications, connecting services together for a seamless user experience. Current customers of our SDK include Uber, Transit (NA), Jorudan (Japan) and Kisio/Keolis (France).

Come join us on this exciting ride as we build the transit technology ecosystem of tomorrow.

The Engineering Team

We believe making great products should be enjoyable and rewarding. Our teams are self organising – most use scrum, kanban or a hybrid approach that gives them the best chance to meet their collective goals. Each team has specialists in dev, test, (sometimes hardware too) and deployment who work together to create fantastic business outcomes for our customers.

We have hack days 6 times a year, with small yet perfectly formed prizes, but mostly we do it for fun, to learn, and to prototype cool ideas that might help our customers.

Of course we have deadlines, but we love what we do and we celebrate our success regularly.
