Senior Fullstack Developer (Backend First)

About JustPark JustPark is the premier partner offering both B2B solutions for destinations and B2C services for drivers, giving us the best of both worlds. We simplify the entire parking experience. From venues and councils to private driveways, our platform makes it simple for drivers to find, book, and pay for parking—while empowering our operating partners to deliver exceptional parking experiences. We’ve always believed parking should be easier—from end to end. That’s why we, two trailblazing companies—ParkHub and JustPark—have come together to make that vision a reality. ParkHub revolutionized event parking in the US, optimizing venue operations for a smoother, stress-free experience. JustPark transformed parking in the UK, turning the hunt for a spot into a simple, seamless task. Now, as one unified company, we’re combining expertise to offer a full-service, frictionless parking solution for both businesses and consumers.
