Are you a Site Reliability Engineer (SRE) with excellent system-, network-, security- and software engineering skills and would you like to contribute to the improvement of information security of organizations worldwide? Then this job opening is an excellent fit for you!  

Guardian360 is looking for an SRE with passion for automation and software engineering to join our team. 


Your role 

Your main challenge is to design, maintain and automate our infrastructure in a Cloud Native environment. You are able to deliver a secure layer for our container orchestration and related components that are used to deliver new features for our partners and customers. Writing tests for everything you build is second nature as you want to provide reliable software that detects potential issues before hitting production.

Instead of messing around with manual deployments, it makes you happy that all deployments are set up using a single source of truth, the GitOps way. All deployments are rolled out in the most automated, simplified, efficient, scalable and secure way. You are critical in looking at the work of other members of the team and wherever possible will go the extra mile to help improve our work in a structural way. Not only by changing the technical components but also in helping your colleagues improve.

You recognize that Site Reliability Engineering is not only a technical role but is a methodology to raise the bar for the whole organization.

The importance of keeping a 24/7 high-uptime customer facing platform running excites you and you go high and above to achieve reliability. People describe you as a control freak, you want to gain insight in all layers of our stack and use observability technology to achieve this.

Besides managing our infrastructure, you are a software engineer at heart and for a chunk of your time you pick up the development of new features for our security platform. Agile is the way you move through life and that’s how you embrace software engineering to accomplish your end goals. Throughout this process you document everything on-the-fly as this is what you naturally love and do. You emphasize the importance in the team that documentation is available for everyone to get started on anything.

You don’t shy away from customer reliability engineering and recognize why understanding the customer’s needs is of upmost relevancy for everything we are building. Your communication skills are fluent, and you are able to carefully listen and read what our partners, customers and colleagues are saying, while at the same time you are able to formulate excellent responses in both written and spoken form.

About Guardian360 

The mission of Guardian360 is to rebelliously increase justice on the digital infrastructure. We strongly believe it is unfair that organizations and people have invested in IT resources and cannot use them without fear of criminals.

We are fulfilling this mission by developing a software platform that empowers people worldwide to be “in control” of their information security. That means empowering those responsible for “the business” to perform risk management. Those responsible for “IT” are empowered to perform those technical actions necessary to increase information security. The rebellious part is that we really work in a different way, we dare to make unpopular choices, we question the sense of introducing more and more functions and data, and sometimes simply make a different choice than others in our industry.

Our colleagues decide how many days a week they work from home and, if even possible, how many days they are in the office. The headquarters of Guardian360 is in Utrecht and is easily accessible by public transport, bicycle and car. It is also possible to work at one of the offices in Rotterdam, Eindhoven, Bodegraven or Zwolle. Our offices are fully equipped: good coffee, tea, club mate, height adjustable desks, collaboration rooms, concentration rooms and gym.
