Front-end Developer | Medior

Job description

Founded and managed by developers, Rentman puts technology first. Our engineers are given all the tools needed to get the job done and are happy. We believe in long-term solutions instead of temporary workarounds. Our young and interdisciplinary team of developers work agile on various bigger and smaller challenging and rewarding projects. We work in two scrum teams and are working on adding a third and forth scrum team in the first quarter of 2021. That's why we look for a Front-end developer with over 4 years of experience.


Our workflow is developer-first, aiming to get things built as effectively as possible. The scrum teams consist of both frontend and backend, as fullstack developers. To make sure we keep short lines of communication with the product owner and quick responses there is a product specialist/manager in each scrum team.


In short, Rentman is a leading software provider for professionals of the event industry. Working under the same roof in the heart of Utrecht (NL), our international team aims to make the lives of event rental companies across the globe as easy as can be. We aspire to make our everyday hustle a growing opportunity, and our workplace exciting to work at.

Front-end stack

  • Angular as our main front-end framework, using mostly Typescript. We are in the transitioning process from AngularJS to Angular
  • SCSS using BEM methodology
  • 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 be separately run on different versions


Projects you will work on

  • Rentman is currently very good in planning equipment from a single warehouse. One big project we are working on is extending this functionality to multiple warehouse solutions. This adds a new layer of complexity since transfers between warehouses should be planned.
  • Another challenging task we work on is creating a history log module. For all changes done in the account projects planning, we want users to be able to see what is done, when and who did it. Building this feature requires a scalable solution that is able to represent the full history of the database.
  • A permanent task is keeping Rentman fast. Some numbers:
    • 40M files hosted
    • 6K databases, containing 1.3M tables
    • Millions requests a month lead to 10K database queries per second
    • We want all back-end responses to take < 100ms
    • We are building a visual crew planner module that should be able to show a full years planning, consisting of thousands of planning entries. It should support concurrent usage and live synchronisation with socket messages.
  • Check out our public roadmap to get an idea of features planned for development


A you get from us

  • full time position (32 hours is negotiable)
  • 25 days of annual leave
  • flexible working hours
  • laptop, ergonomic workstations with sit/stand desks, multiple screens and whatever you need to do your job
  • remote working (also outside Corona times)
  • when using the office: free lunch, fully stocked kitchen and even our own cafe
  • bi-annual company events and spontaneous get-togethers
