Position
Are you passionate about clean code, well‑thought‑out software architecture and sustainable solutions? Then you’ve come to the right place.
We are looking for a team‑oriented Software Developer (all genders) who enjoys building high‑quality software and actively contributing in a young, agile environment.
We work in a hybrid setup: from our office in Vienna as well as remotely from home – within Austria and beyond.
We place great importance on clean code, maintainability, code reviews and open communication within the team.
Your role in the team
As a Software Developer at CNS, you will work together with your team on the continuous development of our applications. You design and implement new modules and services, improve existing solutions and actively contribute your ideas.
You create technical detail concepts for specific functional and technical challenges and support your colleagues along the way.
Sustainable development also includes clear and well‑structured technical documentation – for example regarding configurations, administrative aspects or architectural decisions.
Depending on your experience and interests, you will also contribute to architecture decisions and technical discussions and actively help shape the future of our systems.
What we expect from you
Several years of experience in professional software development, ideally in complex or safety‑critical systems.
Or: you are at the beginning of your career, have completed an education or degree in computer science / software engineering and are eager to deepen your knowledge in practice.
As a Full‑Stack Engineer, you bring solid knowledge of the Java ecosystem and are familiar with common tools and frameworks such as Maven and Spring Boot. You understand how clean backend architectures are built and feel comfortable implementing services as well as integrating them into the overall system.
On the frontend side, you knowReact and are familiar with a typical modern stack including tools like Yarn and Webpack as well as libraries such as Redux, Material UI or Ionic. You have experience in implementing – or a strong passion for creating – well‑designed, performant and user‑friendly frontends, and you value clean structures and reusability.
We strive for a healthy balance between efficiency and well‑coordinated collaboration. In our daily work, we combine elements of agile and more traditional development approaches. As we currently do not work strictly with sprints or daily stand‑ups, you are comfortable working independently, in a structured and self‑organized manner, and proactively driving your tasks forward.
You are confident working across different operating systems – from Windows and Linux to macOS (the latter especially for our mobile app). You routinely use common IDEs such as IntelliJ IDEA, WebStorm or Eclipse, rely on Git for version control and use Jira for tracking tasks and issues.
Onboarding
After your application, we will invite you to a first interview, where we get to know each other in a relaxed atmosphere. We will also provide you with further details about our projects, tech stack and way of working.
The second step of our process is a technical interview, where you will also have the opportunity to meet colleagues from our development team – either in person at our office or remotely.
In a third and final step, you will personally meet additional colleagues from CNS. During this step, we will present you with an offer and discuss the contractual details.
We aim to provide feedback as quickly as possible after each step and keep the overall application process short and transparent.
