Sabrina Müller

Sabrina Müller

Position: Senior Engineer Public Cloud

I work as a cloud engineer for the Open Telekom Cloud, build and test Images in a Linux based CI/CD environment. We are using tools like Diskimage-Builder, Kiwi, Python, Ansible and Git to come along with a fully automated environment. Working in an agile team encourages us to be responsible for the services we care for. It provides us with the flexibility to self-organize ourselves as a team, how the product should look like and where and when we want to work: My main office is in Frankfurt, but most of time I work from home or join my colleagues placed in Darmstadt. Use one of our open spaces, sit down and work with whom you want to do so, it's just that easy. What I like a lot in my team is the spirit of simply doing things, direct customer communication and working the DevOps way. Maybe we´ll meet in one of our desks sharing spaces?

Motto: „Let´s get things done!“

Matthias Rechenburg

Position: Senior Architect Public Cloud

As a DevOp I like to get things done in the most efficient and automated way. My world is the Linux console and my special interests are automation tools. My nickname at work is "AutoMatt" and for all aspects of my work automation is key. On one hand automation allows me to standardize the roll-out and administration of the lots of different cloud services available in Open Telekom Cloud, and on the other hand it also helps me to eliminate repetitive tasks in business processes. Within our agile team my main focus as the Release Manager of Open Telekom Cloud is to provide a secure and stable IaaS and PaaS platform with the latest fancy features to our customers. I love my job and work tasks, because there is always something new to learn every day. I like to take responsibility and T-Systems empowers me to actively be part of changes and improvements. Personally, I enjoy the proper work-life balance T-Systems is offering me by a modern desk sharing and mobile workspace approach plus flexitime.

Motto: „Always keep the balance.“

I provide the necessary means and resources to make sure, work can flow, bottlenecks are tackled and customer value is delivered. I believe in DevSecOps. I like working for the Open Telekom Cloud, because we are a great team, we experiment a lot and we are at the beginning of hyperscale growth.

Motto: „I love cycling: Plan, Do, Check, Learn.“

Martin Schenk

Martin Schenk

Position: Expert Public Cloud Network Architect

The Network is the one piece that enables all other services while keeping all components tight together. Therefore, it is utmost important to ensure that every part of the network layer is operating smoothly and seamlessly. My duty as a network architect is to design new solutions for more simple network topologies, tuning the performance of the already existing network and sharing knowledge about it with the whole team. Working in Open Telekom Cloud is one of the best experiences I was ever given the chance to have in my life. It is inspiring to have a team that takes your ideas and pushes them with you together ---to make things happen every day no one would think them to be possible.

Motto: „The impossible will be done immediately, miracles will take some time.“

Position: Junior Public Cloud Engineer

As a Junior Public Cloud Engineer, I do a lot of different things: From managing our ticket system to automating installations and deployments with Ansible, and everything in between. You can normally catch me early in the morning (7 AM) in our Munich office, as I find the morning hours quite productive. Of course, I need some coffee to be awake at such a time. I have the freedom to decide whether I want to work from home or meet my colleagues in the office. My interests are Linux, Android, Docker, Python, HTML/CSS, and my Raspberry Pi. Apart from tech, I'm a big fan of theme parks. Working for T-Systems gives me the chance to further develop myself: Currently I am taking part in a junior development program. Also, I am a member of #GenerationTomorrow, a community of young employees at T-Systems, where we actively shape the future of our company.

Motto: „Trust me I'm an engineer.“

Abdulkarim Shayeb

Position: Junior Cloud Engineer Open Telekom Cloud

As a Junior Cloud Engineer, I'm currently working in one of the new Squads within the Engineering Team of Open Telekom Cloud. I am fortunate to choose from a variety of tasks to get the most suitable option for me. Monitoring, Automation and Python are the skills, that I'm trying to improve. I have wonderful colleagues: They are supportive, friendly and fun to chat with. Working at T-Systems is very exciting, because we are all working together to make Open Telekom Cloud bigger and better. I work in Bonn and sometimes from home. T-Systems Home-office is an advantage that can be taken from the first day of work, whereas in other companies one must wait for at least six months for such a privilege. Besides all of this, I still have time to do other interesting stuff in and outside of the company.

Motto: „A journey of successful career starts at T-Systems.“

Position: Senior Architect Public Cloud

I’m the product owner for the Compute Squad. My current focus is to drive the Compute Squads, specifically towards the agile approach. In our Squad we have the end to end responsibility from creating new features until their release. Our Squad handles compute component’s demands, releases, changes etc. Working in a Squad helps me to focus on many components of the Squad and also gives me the flexiblity to work on topics such as incidents, bugs, changes, review documents, quality assurance, demands, release process etc.

Motto: „Work hard, play hard.“

Jost Nicolaus

Jost Nicolaus

Position: Senior Engineer Public Cloud

As an Engineer I ensure the development and success of all network-related Open Telekom Cloud features, such as virtual network services, platform firewalls, switches & routers, internet and customer network connections. I love working together with our technical experts in an agile mode, where we as a global team make the decisions and then getting things done. In my leisure time I enjoy watching NFL games in the autumn, baseball during spring and summer and work on my golf handicap all year round.

Motto: „You get what you demand and you encourage what you tolerate.“

Sascha Smets

Sascha Smets

Position: Product Manager Open Telekom Cloud

I am responsible for the Open Telekom Cloud Hybrid product, that is part of our overall Open Telekom Cloud offering. As the product owner, I am working with the respective Squad, but I am also a team member within our Squad, as we can solve our issues and work only as a team. The range of my work is really broad, working from technical details via the product offering, aligning with the colleagues up to customer meetings. Therefore, my work is really diversified and a lot of fun. The whole team is great, especially the spirit of all involved is something, that keeps me loving my job every day.

Motto: „Customer first!“

Alexander Navratil

Alexander Navratil

Position: Chief Architect Public Cloud

I am the visionary conscience of the Open Telekom Cloud: Whilst trying and implementing the hottest hype-cycle features, we still focus on the overall picture and a running product. One major topic is to homogenize the platform and their services. I drive the Architects team to be a support base of knowledge for the whole environment: That means to enable everybody to understand, how complex relationships and dependencies on OpenStack environments are working. I enjoy working for Open Telekom Cloud because of the great team spirit and the benefits from the personal comittment due to our agile way (“swarming effects”). In my leisure time I enjoy kite-surfing, which brings me down to earth and shows me, how easy it is to make me happy.

Motto: „If you don´t believe me, trust me.“
