Engineers /
Full-time /

freiheit.com’s software engineers have been building large-scale software systems since 1999. We are internet pioneers and we have delivered hundreds of projects for our customers that are used by millions of users with thousands of requests per second since then.

In the last two decades we have been constantly reinventing and improving ourselves. Self-Improvement and learning are deeply ingrained into our company's DNA and in the personality of all of our team members. We tackle new and interesting problems all the time and very often create things that nobody has built before.

At heart we are an unusual, innovative and bold engineering company. 85 % of our people are engineers with backgrounds in Computer Science, Physics or Mathematics, many also with strong machine learning backgrounds.

We hire the top ranking students directly from university or from their first work experience and actively develop them to become well-rounded software engineers.

From our Engineering Hubs in Hamburg and Lisbon we work for large and mid-sized companies to reinvent their future with technology. 


    • As a Site Reliability Engineer you apply software engineering principles to run large-scale systems.
    • You are responsible for the reliability and performance of large-scale, distributed systems running in the cloud. You set up the test and production environments together with our engineering teams using infrastructure as code. You automate manual tasks and monitor your clusters on your own responsibility.
    • You are able to do administrative tasks, but you automate any repeating tasks.
    • You’re interested in automation, keeping things simple, and supporting engineering teams to continuously ship great software.
    • The job profile is new and a great opportunity for system administrators or software engineers interested in running large cloud systems.
    • This job requires software engineering, programming and systems administration skills.
    • We have a flexible Hybrid Work model where most people work 2-3 days per week from home.


    • Bachelor’s degree in Computer Science or related fields like Mathematics, Physics or Electrical Engineering
    • Experience with Docker and Kubernetes
    • Experience in UNIX systems administration
    • Programming experience – ideally in Go

    • Bonus skills and interests: 

    • Master or PhD in Computer Science or related fields like Mathematics or Physics
    • Experience in Google Cloud Platform (GCP), Amazon Web Services (AWS) or Microsoft Azure
    • Experience with observability (logging, monitoring, alerting, tracing)
    • Experience with networking
    • Experience with security
    • Experience working with distributed systems in the Cloud (Terraform)
    • Experience in setting up CI/CD pipelines

In our Engineering Hubs in Hamburg and Lisbon you will meet people from all over the world, different cultures, colors, languages, genders and lifestyles. We celebrate diversity and openness. 

When you ask anybody why they are working here, it is pretty likely that people will say “because of the people” and “because I have never learnt so much in my life”. Our company is a place to be yourself, aim high, taking care of each other and growing without limits.

Of course we have a beautiful office in a very nice area of each city, a place to hang-out and play pool and have fun with your team members. But more important is that we offer you the ability to work on interesting things and owning a complete large-scale project from idea to implementation and operations. You have the opportunity to learn from senior engineers, work in a well-organized and well-managed company and start a fulfilling career in tech.

P.S.: Although we visit our customers regularly, all team members are working mainly from Hamburg or Lisbon and not on the customers’ premises.
