Apply for this job

As a Frontend Developer, you and the rest of our international team aim to make the lives of suppliers to the event industry across the globe as easy as it can be. Therefore, you’ll join our young and interdisciplinary team of developers to work agile on various bigger and smaller challenging and rewarding features.

We are committed to developing excellent software and foster an environment of collaboration and trust. Founded and managed by developers, Rentman puts technology first. We believe in long-term solutions instead of temporary workarounds. Our workflow is developer-first, aiming to get things built as effectively as possible.

What are you going to do?

  • Design and implement new features together with frontend and backend developers in your team

  • Guide feature development within your team from design to release as a tech owner together with the product owner

  • Work together with the architecture team to extend and improve the application stack

  • Having fun doing all of the above

Our stack

Rentman is a modern cloud-based web-application our users rely on on a daily basis. Our clients use our app to administer movement of equipment to event locations and back, or to access their data on the go.

From a back-end perspective, Rentman consists of our internal API, a public API and a set of microservices. The internal API is quite intense on complex database calculations.

  • Modern version of PHP and MySQL, used in our internal API

  • Modern versions of Laravel, used by some of the microservices

  • Our backend is deployed on AWS

  • We work based on "Continuous integration" so our systems can be separately run on different version

Our front-end consists of:
  • Current version of Angular as our main frontend framework, using Typescript

  • Compilation and bundling done by Webpack

  • Websockets (NodeJS and SocketIO) to sync data between clients

  • We work based on "Continuous integration" so our systems can separately run on different version

Our testing approach includes:
  • Automated E2E tests with Ghost Inspector, running weekly and on-demand

  • Automated mobile app tests with Appium and Webdriverio

  • Weekly manual regression testing

  • Manual testing on-demand

  • A plan to integrate automated testing more heavily into our CI/CD pipeline


We use the scrum methodology, run two week sprints and have a weekly release cycle. Our four self-organising development teams consist of a product owner and 4 to 6 frontend and backend developers, one of them has the role of scrum master. Each team is responsible for their own product stream. A separate QA team assists the development teams with their testing activities and takes care of manual and automated regression testing and the release process. During a weekly 'Tech Alignment' meeting, developers together with the CTO discuss technology, address technical debt and decide on our technical roadmap. 20% sprint capacity can be used for initiatives on the technical roadmap.

Hiring strategy and internal growth

For attracting junior talent, we yearly facilitate an internship development team for two to three computer science students in their final year, with the intent to offer them a job when they graduate. This 'Team Green' is coached by our medior and senior developers. We strive for a healthy mix of seniority/experience levels in our teams and we want our developers to grow. For that we provide a training budget to be spent on books, conventions and courses. With regular checkins and half-yearly personal evaluations you and your manager work together to shape your path forward, making sure you continue to have an interesting and challenging mix of tasks and responsibilities.
