Giant Army is looking for a part-time video game/simulation tester to join our team. You should be familiar with Universe Sandbox ², and interested in helping us find and fix bugs as we continue development. You will work independently to regularly test our builds and write up bug reports, then work with the team to ensure they’ve been fixed.

You will need a keen eye and love of science, the ability to write clearly, and a desire to rigorously test Universe Sandbox ².

This is an hourly, contract position.

Join us… we’re making something incredible that’s never been done before.


Your Role

  • Create a comprehensive list of features to test and their expected results, and update it as we add new features
  • Use this list to regularly review our internal builds to make sure we haven’t broken anything
  • Review the forums and feedback to identify user-reported bugs
  • Verify that the bug occurs and write a clear description and reproduction steps (so it’s very easy for our developers to identify the issue without spending time figuring it out)
  • Post bugs to our internal Trello board
  • Communicate with our developers on Slack to help squash bugs
  • Verify that tasks, new features, and bug fixes completed by our developers are, in fact, completed

 Ideal Candidate

  • Has already spent many hours exploring Universe Sandbox ² and loves it… and has spotted a bug or two
  • Has experience with/insight into software testing and methodology, and knows what developers are looking for
  • Maintains a flexible schedule which allows for varying hours (depending on where we are in development cycle)
  • Owns both a Windows and a Mac machine and maybe even a Linux machine

Mandatory Qualifications

  • Ability to write clear descriptions and reproduction steps for bugs in English
  • Detail-oriented and an eye for noticing when things aren’t quite right
  • Intuition about science and how our simulations should work
  • Must own a Windows or Mac machine
