Job description

Would you like to help strengthen digital infrastructure and develop the cybersecurity solutions of the future?

For our client Arbit Cyber Defence Systems, we are looking for a skilled and dedicated software developer with a few years of experience (not senior). You have solid practical experience in software development, a firm grasp of fundamental design patterns, and a passion for delivering high-quality code in a professional environment where IT-security and system stability are paramount.

Arbit, located in Hvidovre, develops and produces a portfolio of highly certified cyber defense solutions that enable clients within intelligence, law enforcement, and the military to operate classified, segmented networks based on Data Diode technology. They are a dedicated and motivated team of software developers and system engineers who combine highly specialized technology with deep insight into their clients and a commercial, international perspective.

About the Role and Your Responsibilities

As Arbit's new software developer, you will become a vital part of the entire software development lifecycle. You will have a high degree of independent responsibility for designing, developing, implementing, testing, and maintaining robust IT solutions. Your primary area of responsibility will be Arbit's critical desktop applications (Mainly Linux but also Windows) written in Java and Golang.

You will work in close and dynamic collaboration with the rest of the development team, QA, and project managers. The team actively uses AI in development.

Your Primary Tasks

• Development and Optimization: You will primarily code and implement new software modules and applications in Java, but you will also have the opportunity to work on and contribute to tasks in C# and Golang. At the same time, you will ensure stable operations through maintenance and further development of existing systems.
• Architecture and Design: You will actively participate in the analysis phase and the specification of system requirements. You will brainstorm and collaborate with the team on the overall software architecture and technical solutions, placing high value on our established coding standards and best practices (in line with Arbit's R&D strategy).
• Version Control and Collaboration (DevOps): They utilize GitLab effectively for everything from version control and code reviews to merge requests and building CI/CD pipelines. Your contribution here will be a natural part of your daily routine, which also includes active participation in team meetings and technical discussions.

• Testing and Quality Assurance: You take responsibility for your own code through unit tests and integration tests, as well as supporting system tests to ensure the absolute highest software quality and minimize errors through structured debugging.
• Documentation: You will contribute to producing and maintaining precise technical documentation so that our solutions remain transparent and future-proof.

Who Are You?

You hold a Bachelor's degree in software development or equivalen - and have a few years of experience as a software developer (e.g., 2-5 years). This enables you to work in a structured manner with complex tasks while remaining curious to learn and develop further toward a senior role.

Moreover, we value that you

• have strong competencies in Java and/or Golang.
• thrive in a team environment, naturally collaborate with your colleagues, and bring great energy to the team.
• are detail-oriented and appreciate clean, well-structured code.
