ABOUT THE INTERNSHIP:

Trellisloft is hiring a Software Engineering Intern for Jan 2027. 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. The internship is fully remote. Interns join our Manchester team on daily calls and get a named mentor. Working hours overlap with UK business hours. Equipment is provided, including a laptop.

YOUR PROJECTS:

• Build REST API endpoints and document them in Postman or Swagger
• Fix bugs from the Jira backlog, starting with small, well-defined tickets
• Update the README and internal Confluence pages when you change how something works
• Debug failing builds in the GitHub Actions pipeline and note what caused them
• 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
• Refactor old modules when asked, keeping behaviour the same

WHO YOU ARE:

• Authorized to work in the US. CPT and OPT candidates are welcome to apply
• Available 40 hours a week for the full internship
• Basic understanding of data structures, OOP and how HTTP requests work
• Some experience with Git, even if only on college or personal projects
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Good grasp of at least one programming language: Python, Java, JavaScript or C++

PREFERRED QUALIFICATIONS:

• Contributions to an open source project, however small

WHAT YOU GET OUT OF IT:

• You will ship at least one feature that real users touch before the internship ends
• Writing tests is part of the job here, and you will get good at it
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers
• Weekly 1:1 with your mentor to go over what went well and what to work on next

Program dates: Jan 2027, 4 months.

Intern pay: $40.00 - $56.50/hr
