Job description

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.

About you

We’re looking for someone who can bring their tried and tested experience to JustPark to help us shape our Engineering team. Even with all that experience, though, we don’t expect you to be an expert on our systems or code base from day one!

You thrive in a collaborative environment where feedback is welcome, and you’re open to refining your ideas while supporting others. We appreciate individuals who invest in their craft and prefer to grow within a team.

We value people who are smarter than us and can teach us something new. You’ll be able to stand up for something you believe is right, and challenge when you see something that could be better. And you’ll welcome the challenge from your team when they do the same, because we’re all working towards a common goal.

We’re here to deliver a solution that makes life better for our customers. To do that you’ll need to see beyond just your role and understand how our business fits together to see the impact we all have on one another. You’ll seek out people here at JustPark and in the wider engineering community who inspire you, educate you and show you new ways of working.

We care about quality, and we expect the same from every person in the team. We laugh at our mistakes, but we don’t make them more than once. When things go wrong, we focus on finding a solution, support each other to make it right again and learn from it to do better in the future.
