Software Engineer Intern

The program

Thomas Systems is hiring a Software Engineer Intern for Summer 2027. Our Core Services team is five engineers working fully remote across two time zones. The intern picks up small backend tickets first and moves to bigger features once comfortable. This role is fully remote within the US. Normal working hours, Monday to Friday.

What you'll do

• Add unit tests with pytest or Jest so new code does not lower coverage
• Refactor old modules when asked, keeping behaviour the same
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack
• Debug failing builds in the GitHub Actions pipeline and note what caused them
• Update the README and internal Confluence pages when you change how something works

What we're looking for

• Currently enrolled in a bachelor's or master's program, graduating 2028
• Based in the US for the duration of the internship
• Basic understanding of data structures, OOP and how HTTP requests work
• Some experience with Git, even if only on college or personal projects
• Able to communicate clearly in written English on Slack and in pull requests
• Good grasp of at least one programming language: Python, Java, JavaScript or C++

Nice to have

• Exposure to Docker or a cloud platform such as AWS or GCP

What you get out of it

• How a production codebase is organised, deployed and monitored
• Writing tests is part of the job here, and you will get good at it
• Weekly 1:1 with your mentor to go over what went well and what to work on next

Program dates: Summer 2027, 10-12 weeks.

Pay: $51.50 - $60.00 per hour

Perks
