Backend Developer | senior


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 efficiently as possible. To keep yawns at bay, we keep admin tasks to a minimum and create tools to eradicate repetitive tasks.

We work in 4 scrum teams that consist of frontend, backend and full-stack developers, with a diverse international background. As a senior Backend Developer, you and the rest of your team aim to make the lives of rental companies across the globe as easy as can be.


Are you keen about solving complex equipment availability problems, coming up with high-performance solutions to problems in various areas, writing complex yet effective SQL queries? Are you interested in constantly learning and looking for ways to improve existing code? If the answer to these questions is “yes”, then you will most likely find working on our software stack a true pleasure.

We come from a traditional monolithic PHP background. We have spent 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

  • 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

  • MySQL 8 and modern OO PHP 8 framework

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