Site Reliability Engineer (80% - 100%) Your mission:

As a Site Reliability Engineer for our Secure Access Service Edge (SASE) service, you empower Open Systems to deploy and operate a reliable, distributed service at scale, across multiple platforms. 

You will: 

  • Work closely with engineering teams, product owners, and other stakeholders to define service operations, identify operational issues early and prevent them
  • Help define Service Level Objectives to assess release readiness of all services 
  • Develop software, tooling, and processes to automate our operations 
  • Measure and optimize system performance 
  • Participate in incident management on-call rotation and drive root cause analysis

At Open Systems SREs are driven by improving the operations of our services, measured by the level of service that we provide to our customers, the resources that we need to operate our services, and the interest of our operational work in our Mission Control NOC. SREs work in partnership with platform and service engineering teams in different capacity—from consulting to joint engineering projects—to drive the operational improvements across the entire lifecycle of our services.

As part of your SRE responsibilities, and through the Open Systems training and courses, you will become certified as a Mission Control Engineer, providing you with knowledge in a wide area covering networking and security topics. This will give you the opportunity to visit our Mission Control NOC in Honolulu for deployments of 2 to 3 months, where travel and accommodation is also afforded to your partner and children.

Your qualifications:

You are strong in either Software Engineering or Networking and Security Operations and have an interest in developing your skills and solving problems at the intersection of both. You are motivated to learn new skills and expand your existing theoretical and practical knowledge in training programs offered by internal domain experts and team colleagues, and ideally, you bring some of the following skills to the table: 

  • University degree in Computer Science, or equivalent professional experience
  • At least 2 years of SRE, software development, DevOps, or security automation
  • Strong conceptional understanding of scalable system design
  • Full ability to design, test, and release code in general-purpose languages such as Go or Python and scripting (Bash)
  • Familiarity with GitOps, Terraform, Kubernetes, Prometheus, as well as major clouds (Azure, AWS, GCP...)
  • Interpersonal skills, ability to collaborate and build trust across teams to design and deliver shared solutions

You may already have experience with the whole breadth of the SRE role already, but do not let it stop you if you do not. We also support you making a transition to SRE from a strong skillset in software engineering, DevOps, or platform engineering. In that case you should be able to explain why would want to make this transition.

What we offer:

You will join our growing SRE team, and work with agile method in coordination with software and product engineering teams. You will have the opportunity to work remotely from Switzerland, Germany, Austria, the Netherlands, or the United States, or be based in one of our offices in Zürich, Bern, Düsseldorf, Vienna or Redwood City. You will have the option to work full-time or part-time 80%.

Open Systems will offer you interesting challenges in the dynamic and global environment of SD-WAN and cybersecurity. You will be in a work environment in which innovative solutions, rapid development times, creativity, and open communication are practiced and continuously fostered. The pursuit of technical advancement is at the center of our attention. Our employees are known as enthusiastic, humorous, and passionate individuals. It’s all about people because it’s them who make us stand out in the marketplace, not our technology.
