First seen by Alion on Nov 11, 2026.
Are you a Python programmer? Are you driven by system-level challenges? Join the Software Test Solutions at Westermo as a Software Developer!
Are you our next Software Developer?
Software Test Solutions develops our in-house test framework, which is used to test our products, and plays a critical role in ensuring product quality and reliability. Many teams rely on the accuracy of our test results, which makes our work essential for validating our products against their specifications.
We are looking for a software developer who thrives in an agile environment and wants to be part of a team that builds and maintains this framework and its tools. The framework is used for system-level testing of our products in network solutions, running on dedicated test systems.
Our department is made up of two teams: the Test Framework team (the role described here), which schedules and runs tests, processes the test results and maintains the test systems, and the Test Developer team, which develops and maintains tests for our operating system WeOS. We promote close collaboration between the two teams, so your work won't necessarily stay limited to the framework – there's plenty of room to explore and contribute across both.
In your role, you will be:
Programming primarily in Python (and Go), working with tools such as Docker and Kubernetes.
Analysing test results and troubleshooting and refining the framework to keep it reliable.
Maintaining and developing the test systems, with the devices under test, that the framework relies on.
Extending the framework to support new WeOS functionality.
Developing the next generation of our test framework to meet future demands on scalability, including virtual testing, and reduced complexity for end users.
Working with both front-end and back-end development of the web interfaces for configuration and visualization of test results.
We think about automation in everything we do, and we are always trying out new technologies that help us meet current and future demands. We use Jira for planning and tracking work, and keep improving our Agile methods. AI is also a natural part of our daily software work, and we are exploring how to put it to even better use.
So, who are we looking for?
You have an academic background in computer science or similar, and you’re motivated by solving real problems with smart solutions. We value teamwork, and hope you do, too. You enjoy both technical development and team collaboration, and you share your knowledge just as readily as you ask for help. You are curious and innovative, comfortable in an agile environment, and like to try, test, and learn with colleagues.
Further, we want you to be:
Experienced in Python development and eager to deepen your skills.
Comfortable working in a Linux environment.
Familiar with software engineering tools such as source code management, CI/CD, containers, and web development (front-end and/or back-end).
Interested in networking technologies.
Fluent in English and Swedish.
Oh, and don't worry, if you're not an expert in all the things described – you'll learn.
In return, we offer: You will be working at the forefront of technology in a friendly, open culture where you get the opportunity to learn from skilled colleagues every day. A mature and caring leadership in a flat organization. Through our collective bargain agreement you will be covered in terms of insurance, pension and other benefits. We like to have fun together and we regularly enjoy sports and other social activities as a team. We believe that magic happens when people meet. We are a learning organization and we truly love to try new things, think outside the box and be innovative together!
