Software Engineering Intern (Remote)

ABOUT US:

Buckeyewater Labs is a small team of former military and law enforcement analysts doing pen tests and incident response. Certifications across the team include OSCP, GPEN and CISSP. Founded in 2002, we now have 13 employees.

THE INTERNSHIP:

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. Fully remote. You can work from anywhere in Japan. Most of our work is async, and meetings are kept short. We send you a laptop and the accessories you need on day one.

RESPONSIBILITIES:

• Pair with other engineers over screen share to work through tricky problems.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.
• Debug failing builds in the GitHub Actions pipeline and note what caused them.
• Add unit tests with pytest or Jest so new code does not lower coverage.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Update the README and internal Confluence pages when you change how something works.
• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.

REQUIREMENTS:

• Based in Japan for the duration of the internship.
• Available for the full internship period.
• Currently enrolled in a bachelor's or master's degree, graduating 2027.
• Some experience with Git, even if only on college or personal projects.
• Own laptop with at least 8 GB RAM and a reliable internet connection.
• Must be able to overlap at least 4 hours a day with the team's working hours.
• Basic understanding of data structures, OOP and how HTTP requests work.
• A GitHub profile with at least two projects you wrote yourself.

WHAT YOU GET OUT OF 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.
• How a production codebase is organised, deployed and monitored.
