Are you experienced in Javascript and would you want to help develop integrations and applications in Zoho CRM? On top of that, would you want to get involved with building and further developing a completely new PHP website? While doing so, would you like to contribute to making the Netherlands more sustainable? Check out this vacancy!

Your job as Developer

For part of your time, you will develop in Zoho Creator, both low-coding and scripting with Zoho Deluge (almost similar to JavaScript). Zoho as a CRM solution is being used worldwide by many different companies and gaining popularity in the Netherlands as well. There is a solid knowledge base of the CRM system within your team.

To make HalloStroom grow, professionalize and expand, we consider an impeccable CRM system crucial to our success. Smooth integration with other applications we use is among the most important things.

You will get to work in a team with another Developer/Application Specialist and a System Engineer/Developer, guided by the CTO. If necessary, we could ask you to support system engineering in case of the absence of your co-worker.

What do you need

  • a higher vocational level of education and at least 2 years of work experience, preferably IT-related studies
  • good knowledge and understanding of both English and Dutch, preferably B2/C1 level
  • basic knowledge of JavaScript or a different scripting language such as Python

Plans for an extensive state-of-the-art PHP website are in an advanced stage. You and your team will work on the integrations with Zoho, Hubspot, or Steam. Expanding your knowledge of PHP will be useful.

Experience with Windows 10, macOS, and/or Office 365 is nice to have. A friendly form of sarcasm is common to you.

What's in it for you

Full-time employment at a young company with a sustainable mission: making the Netherlands run on clean and sustainable energy. You will have a lot of freedom and responsibility, and the opportunity to further develop yourself. You will get to work closely with nearly every part of the organization and your work will impact the total workflow quite a lot.

Apart from this, you can count on:

  • A monthly gross salary of 2500,- to 3500,- EUR, depending on the experience and expertise you bring
  • Good benefits like a free gym at our facility
  • A beautiful office right across the train station in Gouda
  • Awesome company trips
  • a well-stocked fridge every Friday.

HalloStroom is a scale-up located in Gouda with about 50 employees, working to bring sustainable energy within reach for every household in the Netherlands. At the moment we do so by renting out solar panels but in the near future, we would also want to offer other solutions, like heat pumps or local energy storage.
