We are a fast growing company that is looking for someone to join our infrastructure team in their task of creating and maintaining a telephony platform. You are excited by improving the scalability of the platform and implementing new features. We are always creating and updating features like queues, IVRs, call recording, and voicemail.

You will get all the room you need to do things right because that is more important to us than being on time. We use large open-source projects that we actively contribute to. Working outside regular office hours is an exception and not the norm.

What is Spindle?

Spindle is a purpose-driven enterprise connecting the world using free (as in freedom) communication.

We adhere to an agile way of building software. We tweak the process we use to build software as much as the software itself. Call it meta-agile. Seriously though, you should be comfortable in a constantly changing environment.

We work with Holacracy. We are a purpose driven organization where authority is distributed to roles instead of people. We choose not to have managers because we believe that all colleagues use their expertise to make the right decisions regarding their roles and contribute equally to the direction of the product as well as the organization.

We strive for quality over quantity. We share our expertise between developers by reviewing all code before it is deployed. We have two products that bring us a lot of pride and joy: VoIPGRID and Lily.

We are committed to open source software. We share our own software where possible. Actively contributing to open source projects is regarded as part of the job. Because we are proud of what we do, we like to share our knowledge in blog posts and at meetups and conferences.

What we offer

We offer you the opportunity to work on software that strives to make sure that communication is always yours and yours alone. We also offer:

  • A relaxed and welcoming culture with celebrations, events, hackathons, and trips
  • A competitive salary
  • A good pension insurance
  • An annual study budget and study days
  • Two weeks leave for new parents
  • An hour of lunch time in which we enjoy a delicious lunch provided by Spindle
  • A Spindle company bike
  • A sports and wellness subscription
