We're looking for
a DevOp

We are looking for an experienced and skilled DevOp to strengthen our team. You will join the infrastructure team to expand VoIPGRID, the ever growing VoIP platform offered by our partners to SMEs across the Netherlands.

It's nice to have the freedom and the resources to decide what is best for our infrastructure.

Bram Noordzij

What will you do

In your role as a DevOp, you will be working with the team to prepare smooth paths towards adding features and improvements to our telephony platform. With your knowledge and effort, we will further reduce the potential tensions surrounding deploys, upgrades, and other changes to the VoIPGRID platform. You always strive to seek the right balance between stability and agility. You do this by recognizing opportunities to automate things and follow up on them.

Our stack is built upon Asterisk, OpenSIPS, MySQL, Bash, Python and some more. We are currently migrating from Puppet to Saltstack for our VoIP stack. Also, we are moving towards a containerized setup for the other parts of the stack.

Your profile

If you recognize yourself in the following profile, we might be a good match!

You have:

  • A well-founded opinion about how to go about automating all the things
  • Experience with Linux System Administration, including HA setups, diagnosing,
    troubleshooting, and supporting production systems
  • Knowledge of a programming language (as mentioned above, we work with Python)
  • Experience with a configuration management tool, such as Saltstack or Puppet
  • Created and maintained monitoring and testing tools
  • An interest in or curiosity towards SIP/VoIP telephony

What we offer

Besides the primary salary, you can also enjoy:

  • An hour of lunch time in which we enjoy a delicious catered lunch
  • Healthy stuff: a Spindle company bike and a sports and wellness subscription
  • A good pension insurance
  • An annual study budget to expand your knowledge
  • A workplace which you can arrange the way you like it. We want you to be able to work at your best and provide all the stuff you need to do so
  • A relaxed and welcoming culture with celebrations, events, hackathons, and trips
  • Great time off benefits when a new child arrives in your family

Who we are (buzzword bingo)

We were the cloud before we knew that the cloud was a thing. We started out building a PBX for customers that don't need a PBX server in their offices. Before we knew it, VoIPGRID was the first fully functional cloud hosted PBX. Hosted on a fully redundant setup which we manage. We also leverage cloud-based solutions as we see fit for several parts of our infrastructure.

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, it helps to be comfortable in a constantly changing environment, where you have a say in the direction it should be changing.

We ask all developers to share their expertise by doing code reviews and never be afraid to have their code scrutinized by others. No code is shipped without tests that prove it works.

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.

We also like to share our knowledge in our blog posts and at meetups and conferences. We’re giving masterclasses and workshops at schools to excite the next generation of developers.

We work with Holacracy. This means we are a purpose driven organization where authority is distributed to roles instead of persons. We don’t need managers because we believe that all colleagues use their expertise to make the right decisions regarding their roles. It's up to you to do what you do best!
