Job description

We are Rentman!

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.

The team 

Founded and managed by developers, Rentman puts technology first. Our engineers are given all the tools needed to get the job done and be happy doing so. We focus on one product and believe in long-term solutions instead of temporary workarounds.

Our young and interdisciplinary development team of developers work agile on various bigger and smaller challenging and rewarding projects. Our workflow is developer-first, aiming to get things built as efficiently as possible. To keep yawns at bay, we keep admin tasks to a minimum and create tools to eradicate boring and repetitive jobs. Plus, we don’t work with deadlines, because we believe in the intrinsic motivation of developers.


We come from a traditional monolithic PHP background. We have spend a fair amount of effort on decoupling our services and building the leanest and fastest data gateway we could think of. Along the way we embraced microservices, a serverless architecture (AWS Lambda & Fargate) for some of our services, came up with our own query language and designed a modern build- and deployment process that fits our organisation.

Backend stack

  • modern OO PHP 7 framework

  • MySQL 8

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

  • AWS services are the backbone of our stack (ECS, Fargate, RDS, SQS, S3, Lambda). We design for high-availability and we deploy our services in multiple regions. We utilize docker containers a lot and have a CI/CD pipeline for most of the microservices we deploy

  • we work based on "Continuous integration" so our systems can be separately run on different versions

Projects you will work on

  • historically our data used to live in dedicated silos per customer. We’re moving user profiles to the global space and utilize API’s between the silo’s to help our customers collaborate more effectively. You will work on matching data and connecting our customers.

  • relational database model design 

  • refactor legacy parts of the system for team and company growth

  • check out our public roadmap to get an idea of features planned for development
