Summer Software Engineering Intern (Remote)

About us:

Our main product is a payroll and timekeeping app for hourly workforces, sold by subscription and supported from Valladolid. Most of what we build is back-office software for property managers, including lease tracking, work orders and tenant payments. On-call rotates weekly and pays a flat stipend whether or not the pager goes off.

The internship:

This is a hands-on coding internship. Most of the work is in Python and Node.js, with some SQL and a bit of shell scripting. Remote within Spain. The team meets in Valladolid once a quarter, travel covered.

Day to day:

• Add unit tests with pytest or Jest so new code does not lower coverage
• Update the README and internal Confluence pages when you change how something works
• Refactor old modules when asked, keeping behaviour the same
• Pair with other engineers over screen share to work through tricky problems
• Build REST API endpoints and document them in Postman or Swagger
• Raise pull requests on GitHub and respond to code review comments within a day
• Present a short demo of your work to the team every two weeks

What we're looking for:

• Based in Spain for the duration of the internship
• Eligible to work in Spain
• Available for the full internship period
• Good grasp of at least one programming language: Python, Java, JavaScript or C++
• A GitHub profile with at least two projects you wrote yourself
• Basic understanding of data structures, OOP and how HTTP requests work

Duration: 5 months

Start date: Jan 2027

Stipend: €1,200 - €1,550/month

Perks:

• Possibility of a full-time offer
• Paid public holidays
• Internet allowance
• Mentorship
• Certificate of completion

Duration: 5 months. Start: Jan 2027.
