Senior Backend Engineer

ABOUT US About JustPark JustPark, established in 2006, is the UK’s favourite parking app, parking a car every 2 seconds and processing £100m+ of parking income for our partners each year. With 13 million drivers and more than 250,000 spaces, we’re proud to work with some of the UK’s biggest Local Authorities, hotel chains and car park operators. JustPark markets and monetises both unused residential driveways and under-utilised car park capacity, benefitting drivers and creating revenue for space owners. Uniquely in the industry, we focus on both the driver and the operator experience to make parking better for all stakeholders. In addition to working with traditional parking real-estate, we also work with 10,000s of independent landlords and small businesses. We pride ourselves in our ability to provide exceptional service, a smooth onboarding process and being on the cutting edge of innovation.

Our merged organisation Following the merger in April 2024, JustPark and ParkHub now form one of the largest parking organisations globally, serving over 20 million drivers and more than 500 B2B customers, with a combined booking volume exceeding $1 billion. This makes 2024 a hugely exciting time to join our business and we are looking for new team members that will help us execute on the opportunity now in front of us. ABOUT THE ROLE This position is all about building a backend that delivers new tools and products to 10 million users, ensuring our customers experience a world-class service from our products. As a senior engineer, you will contribute to key architectural decisions that shape the future of the stack at scale. You’ll also be expected to take charge of technical delivery and guide the more junior members of the team. ABOUT OUR TECH STACK We use Laravel 10 and PHP 8.1 as our daily drivers. Our current architecture is fairly monolithic, predominantly in Laravel as our main API and remnants of legacy desktop. We have surrounding services written in Go, Java, Python, and Node, with state held in Redis, MySQL, and PostgreSQL. Primarily, the surrounding microservices are written in Go (around 25) with some legacy Java/Python services. We operate in a cloud environment, utilising Google Cloud, and our infrastructure is cloud native - our entire production, staging, and development stack is Kubernetes and Docker. We work to agile methodologies. Peer review of work is expected from all engineers, and we work in a test-driven fashion as often as possible. We are big on pair programming and encourage it wherever possible.
