Summer Software Engineering Intern

Chartered in 1980, Denis Community Bank has stayed independent through several rounds of mergers in the area. Most deposits come from local households and businesses, and most loans stay in the communities we serve. Founded in 1980, we now have 120 employees.

About the role:

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. Remote, open to candidates across Belgium. Normal working hours, Monday to Friday. Please make sure you have a quiet place to work and a solid internet connection.

Responsibilities:

• Build REST API endpoints and document them in Postman or Swagger.
• Present a short demo of your work to the team every two weeks.
• Pair with other engineers over screen share to work through tricky problems.
• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.

Who can apply:

• Currently enrolled in a bachelor's or master's degree, graduating 2026 or 2027.
• Eligible to work in Belgium.
• Must be able to overlap at least 4 hours a day with the team's working hours.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• Own laptop with at least 8 GB RAM and a reliable internet connection.

Bonus points:

• Contributions to an open source project, however small.
