Senior Backend Software Engineer

Our Mission

Our mission is to make rental administration easy for tenants and landlords. Managing rental properties is complicated, whether you’re managing a single property or hundreds. We have developed a platform that removes all the frustrations of being a landlord by leaning on technology, automation and amazing customer service. We want our landlords to spend their time adding value to their portfolios whilst making sure tenants have the best renting experience they can get.

Join our ambitious startup to make a real change in an industry that truly needs it.

Our Engineering Environment

We rely entirely on a serverless infrastructure on AWS. Most of our micro-services are written in Java at the moment, but we're experimenting with Kotlin and TypeScript. The architecture is based on Clean Architecture and are event-based, using AWS Lambda, SQS, SNS, S3, and DynamoDB.

Our frontend is a React app based on Next.js, styled-components and our own component library built with Storybook – yes, everything is written in TypeScript.

We build our product through a process inspired by experiments. First, we test ideas, job stories and product market fit with a pretotype which is a quick experiment with little software. Once we have an understanding of the jobs-to-be-done and the market we either move on to a prototyping stage with a little more software, or straight to the “real” implementation. We learn a lot during these initial phases while using only limited resources. And we find that this process allows us to move fast and stay agile while giving us a high degree of confidence in the product we deliver. It’s usually not possible in other industries, but in property management everything is handled manually so we are just as good as status quo.

The Product team uses Scrum. You will not be limited to a certain technology or area, but get responsibility across the product, and it is expected that you contribute to the team and use your skills broadly within the product team.

Needless to say, as we process the rent for thousands of homes and offices we are serious about security and privacy.


As a person you thrive in a position where you have a lot of responsibility, work in a small team and also challenge the existing processes, the team, the product and yourself.

Ideally you have:

  • 3+ years of software development experience in Java or Kotlin

  • Experience consuming and creating APIs

  • Experience with (and contributing to) a component library

  • Experience with different testing strategies (unit testing and manual testing)

  • Worked with distributed systems and event based architecture

  • Ability to communicate well about your own code and others code

  • Some experience with AWS Lambda, SQS, SNS, and DynamoDB is welcomed.
