Java Tech Lead - Smart City

Hey! Nice to see you!

Let’s share our stories to get to know a bit better…. We are business and technology enthusiasts constantly hungry for new challenges, self-development, and development, and nothing motivates us more than great software products and happy customers.

At Incubly, we believe that great people want to work with great people, so we started building a company that would attract great minds and allow us to achieve everything without feeling like we're just working, but rather having fun. Our mission is to mainly support tech companies and startups (scaleups) in fast, high-quality scaling up of their teams and boosting their product development, testing, and deployment so that we can succeed together.

We are currently working with a leading global mobility platform that includes brands like EasyPark, Flowbird, RingGo, ParkMobile, and Parkopedia. Active in over 90 countries and 20,000 cities, Arrive helps make urban mobility smarter and travel easier through solutions like smart payments, optimized parking, and EV charging. It’s about more than movement—it’s about creating more livable cities and better travel experiences.

As a Tech Lead, you will play a dual role of execution and leadership. You will drive the technical direction of your team, make strategic decisions, and ensure alignment with business goals.
