Summer Software Engineering Intern

About Plowshare HQ:

Our audience is small but loyal: about 40,000 newsletter subscribers who actually open it. Growth has come from search and word of mouth, not paid ads. We started in 2008 and have grown to about 34 people.

About the role:

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. The internship is fully remote. Interns join our Sunnyvale team on daily calls and get a named mentor. You will need at least 3 hours of overlap with US Pacific time.

Day to day:

• Refactor old modules when asked, keeping behaviour the same
• Build REST API endpoints and document them in Postman or Swagger
• Write and test backend features in Python or Node.js under the guidance of a senior developer
• Update the README and internal Confluence pages when you change how something works
• Present a short demo of your work to the team every two weeks
• Add unit tests with pytest or Jest so new code does not lower coverage
• Pair with other engineers over screen share to work through tricky problems
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack

Who can apply:

• Eligible to work in Spain
• Available for the full internship period
• Based in Spain for the duration of the internship
• Currently enrolled in a bachelor's or master's degree, graduating 2027 or 2028
• Available for 30 to 40 hours a week for the full internship period
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Good grasp of at least one programming language: Python, Java, JavaScript or C++
• Basic understanding of data structures, OOP and how HTTP requests work
• Able to communicate clearly in written English on Slack and in pull requests

Nice to have:

• Contributions to an open source project, however small
• Knowledge of Linux command line basics
• Any previous internship, hackathon or freelance coding work

What you get out of it:

• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers
• You will ship at least one feature that real users touch before the internship ends

Duration: 6 months

Start date: Feb 2027

Stipend: €2,050 to €2,450 per month

What we offer:

• Certificate of completion
• Possibility of a full-time offer
