We are looking for developers and software engineers who are at the beginning of their careers. There is also room for students, provided you are available for two or more days a week.

What do you do as a Junior Developer at Copernica?

As a Junior Developer, you will have a diverse and challenging set of tasks. In this role, you will not only learn how to write and maintain code but also how to structure and document it effectively. By analyzing and resolving bugs, you will enhance your problem-solving skills and insight.

Depending on your interests, capabilities, and availability, you can be assigned to various departments. For example, you can join the research & development team (if you want to develop software) or the operations team (if system administration is your thing).

After an initial training period during which you will get to know the different departments and become acquainted with our technology stack, company culture, and business processes, we will find a suitable place for you within the organization.

What technologies will you work with?

Developers at Copernica are versatile, and there is a degree of freedom to choose other platforms. However, you will frequently encounter these technologies:

  • Kubernetes, Linux, and Docker for hosting.
  • C++, PHP, and JavaScript as programming languages.
  • HTML and CSS for frontend development.
  • Various database systems like MySQL, MariaDB, SQLite, PostgreSQL, and MongoDB.
  • Version control via Subversion and Git.
  • RabbitMQ as a queuing system.
  • MailerQ as an MTA.

Since Copernica is an email company, you will also come into contact with network protocols like DNS and SMTP, and email protocols like MIME, SPF, DKIM, DMARC, and more.

Who are you?

You have completed a Bachelor's or Master's degree, preferably in a technical field. Experience with Linux (Ubuntu), JavaScript, PHP, and/or C++. Excellent command of both Dutch and English, both written and spoken. If you do not meet all the criteria but are dedicated, resourceful, and curious, please contact us. We are happy to discuss the possibilities.

What can you expect from Copernica?

You can always use our pleasant office right next to Amsterdam Central Station, but remote work is also possible. In both cases, we provide you with the facilities you need to work effectively, not only for your laptop but also for your desk and chair.

In addition to a generous salary and holiday pay, Copernica offers stock appreciation rights that allow you to build a virtual stake in the company and grow with Copernica. We also reimburse your travel, internet, and phone expenses, provide a training budget, and offer a pension plan.

Our team is relatively small, young, and highly educated. To strengthen cohesion within the team, we offer an informal corporate culture and regularly plan social events both domestically and abroad. If you don't meet all the criteria but are dedicated, resourceful, and curious, please still reach out to us. We'd be happy to discuss the possibilities.
