Backend Software Engineer

Rotterdam - Fulltime - Team: Development 

Join TreeHouse - the largest online rental platform in the Netherlands! We're looking to expand our engineering team in Rotterdam immediately. Curious about this exciting opportunity?

About us

Every month, we assist over 3 million home seekers in finding their new home. We do this with and for home seekers, and with the CRM package Pararius Office for real estate agents. All these labels are part of Treehouse B.V.

Our enthusiastic team of about 80 colleagues operates from our offices in Rotterdam and Breda. Despite our growth, we work in small, multidisciplinary teams, each location having its own goals, allowing for a strong focus on product development. You'll have plenty of freedom to contribute to these efforts.

We believe in constant growth—both for you and the organization. Our motto: if it works, it works. If it doesn't, we fix it. This means you and your team can think outside the box and experiment to find the best solutions. You're smart, so let's put that to good use!

What will you do?

As a software engineer, you'll be part of the Leadflow Team, collaborating directly with Derk Jan, Shannon, and Bogdan, alongside product owner Alex and UX designer Rachid. This multidisciplinary team (backend, frontend, dev-ops, and UX) is responsible for all our websites where supply and demand meet. Key areas you'll work on include our search engine, daily matching ad delivery, and enabling users to respond to property ads.

Together with your team, you'll design and create solutions using the best-suited technologies. We release these solutions in small iterations, focusing on building new services in the cloud (Google) and aren't afraid to move away from old techniques.

Our tech stack includes PHP, Symfony, React, PostgreSQL, Elasticsearch, and some Python for mail annotation. Our development environments run on Docker Compose, with production orchestrated by Kubernetes.

We automate testing with PHPUnit and Codeception and strive for Continuous Deployment—every release is just one merge button away from production. We're also constantly experimenting with new technologies like Google Cloud Functions. We don't expect you to master all our techniques and methods right away; we offer ample opportunities to learn.

Our vision

We don't believe in standing still; we want you to grow continuously, just like the organization. This means you can think outside the box and try everything. We value the knowledge and skills of our engineers and aim to find the best solutions together. You're smart, so let's make the most of it. It's crucial that you have a passion for coding and a proactive attitude.

What can you expect from us?

We expect a lot from you. In return, you can expect from us:

  • A Mac (or Dell) to work on.
  • An informal atmosphere where individuality is valued—you can be yourself with us.
  • Enthusiastic, young colleagues and an inspiring office in Rotterdam (Blaak 555) with a fantastic view of the city.
  • Regular (usually) joint lunches, Friday beers, and various fun team outings throughout the year.
  • Excellent secondary benefits, including a pension plan where we cover 70%.


Does this sound like your ideal job? We'd love to receive your motivation and recent work experience. You can send your CV, but we're more interested in the websites and blogs you frequently read, the podcasts you listen to, the conferences you've attended, and anything else that shows who you are and what you can do. In other words, we'd prefer your GitHub account over a traditional CV.
