Software Developer and Troubleshooter

We have the tools, the problems, and the only missing link is you.


At Westermo quality is everything – the products, the people and the organization.

Welcome to a rapidly growing international company, thriving at the forefront of cutting-edge technology. Westermo develops and manufactures advanced devices for industrial data communication, used in mission critical installations and harsh industrial environments. The very robust and secure communication networks built with our products provide high value for our customers.

We are passionate about taking advantage of the growth opportunities in our market. The work environment is very dynamic. Our people are dedicated and loyal, which create a fantastic team spirit. Everyone is expected to take initiative and our flat organization creates efficiency and provides opportunities for those who are closest to the task of solving it. We are devoted to delivering the best industrial network solutions. At Westermo you will have a clear impact on the results of your area of responsibility.  


Are you our new Troubleshooter?

Westermo provides networking  solutions for some of the most demanding applications imaginable, from onboard trains to the bottom of the ocean floor. We measure uptime in years. To deliver that kind of reliability, we build our software on one of the most battle hardened technologies in existence; the Linux kernel. 

We strive to use Open Source components whenever possible and to act as responsible members of those communities by contributing back the changes and improvements we make. 

Leveraging recent offloading support for hardware Ethernet switch ASICs in Linux ("Switchdev"), along with hundreds of other OSS packages, we build our own network operating system, "WeOS". Westermo is looking for developers keen to build new functionality for our customers, while improving the core components we rely on. 

As a team, we value openess and sharing of knowledge, recognizing that all members are juniors on some topics and seniors on other. We give no refuge to holy cows or the status quo, new ideas about how we should build our platform are always welcomed and encouraged. We pride ourselves on being able to change our minds the second we hear a better solution to a given problem. 

We work with the following core UNIX technologies: 

  • GCC 
  • Make 
  • GDB 
  • Emacs (or VIM if you must) 
  • Tcpdump and Wireshark 
  • Sometimes oscilloscopes 
  • Sometimes soldering may be required 


So, who are we looking for?

  • Great C-programming skills
  • Experience working with the Linux-kernel and Open Source
  • Experience and interest for Embedded systems
  • It’s a plus if you have worked with Cyber Security
  • Certifications in Agile/Scrum is meritorious
  • Fluency in English, and at least beginner-level in Swedish.


Inhouse tools are built around Mantis, GitLab, Jenkins.  We have onsite license for Coverity Scan, and IXIA ANVL for network protocol testing, and more.  We have the tools, the problems, and the only missing link is you. 

Oh, and don't worry, if you don't know much about OSI layer-2 protocols, distributed systems, embedded software already – you'll learn.  You've already gotten this far. 

In return, we offer: Great opportunities for personal development, motivated and competent colleagues, mature and caring leadership, good coverage through our collective bargain agreement and challenging work. With our focus on a healthy and fun workplace with several regular company and team activities, we offer an environment where you can perform and enjoy!

And we actually live our company values!
