Linux Systems & Software Engineering intern

About Visar Systems

Visar Systems AB is a Swedish cybersecurity company developing secure computing platforms for critical systems with demanding

regulatory and certification requirements.

Our core product, DeeDee, is an open and Debian-compatible Linux operating system designed to give organisations a secure and

stable foundation without unnecessary vendor lock-in. We believe that digital sovereignty, transparency and long-term

maintainability are essential for systems operating in critical environments.

Visar Systems was founded in 2025 and is based in the Luleå region. We are a close-knit team of three people with experience in

software development, systems design, large-scale capacity planning, cybersecurity and business development.

Our core product is operational and is already being evaluated in live customer environments. We are now turning early deployments

and customer-specific integrations into a scalable commercial product.

About the internship

We are looking for a technically curious and versatile intern who wants practical experience across software development, Linux

systems, infrastructure and customer integration.

This is not an internship built around one isolated task. Depending on current priorities, you may write code, package software,

improve development processes, troubleshoot Linux environments, support customer integrations or produce technical documentation.

You will work closely with our technical team and receive guidance from people with experience in secure systems, software

development, infrastructure and large-scale operations.

We also value initiative and independent problem-solving. You should be comfortable investigating technical problems, asking

relevant questions and moving your work forward within established technical and security frameworks.

What you may work with

Your assignments will be adapted to your existing skills, interests and development goals. They may include:

The balance between programming, Linux systems, infrastructure, integration and documentation will depend on your background and

the projects underway during the internship.

Visar Systems operates its own infrastructure wherever practical. We favour solutions that support digital sovereignty,

transparency and long-term independence.

Who we are looking for

You do not need to be an expert in every area. We are looking for someone with a broad technical foundation who can apply existing

knowledge to new problems and is comfortable moving between different technical responsibilities.

• Academic studies, professional experience or substantial personal projects within computer science, software engineering, IT,

cybersecurity or a related field.

You must be comfortable working in an environment where security requirements influence which tools, platforms and working methods

can be used.

Additional advantages

Experience in any of the following is beneficial but not required:

We also value open-source contributions, home labs, Linux administration, software packages and other hands-on technical projects

completed outside formal employment or education.

Security and trust

Our products are designed for critical environments, including defence, industrial systems and energy infrastructure.

Swedish citizenship or an existing security clearance is not a formal requirement. However, we maintain strict internal security

policies and conduct an internal security assessment and background check as part of the selection process.

Location and working arrangements

The internship can be completed remotely. However, our team is based in the Luleå region, and it is an advantage if you live

nearby or can participate in on-site activities when needed.

Being close to the team may provide additional opportunities to work directly with our infrastructure, participate in technical

discussions and join customer or partner activities.

Why join Visar Systems?

You will work with a functioning cybersecurity product as it moves into customer pilots, commercial deployments and further

development. The internship provides insight into the complete technical environment rather than one isolated part of the

development process. Your work may span software, Linux, infrastructure, security, documentation and customer integration.

This opportunity is particularly suitable for someone who enjoys technical variety, takes initiative and wants to understand how

secure systems are developed for regulated and critical environments. If available, please include links to relevant GitHub or

GitLab repositories, open-source contributions, home-lab projects or other examples of your technical work.

Language requirements

Professional working proficiency in written and spoken English is required.

• Continued employment: Employment may be discussed after the internship. This depends on Visar Systems’ future financing,

business needs and the mutual fit between the company and the intern. Continued employment cannot be guaranteed.
