Game Software Tester, Battle Road [Orlando]

About the role

Onebrief is building a new category of software for military planning and operational coordination, and this role sits at the intersection of that mission and the gaming technologies that power it. You will own the validation of core simulation systems by executing structured tests that reveal how well AtomEngine handles complex, evolving scenarios. This position requires you to act as the critical eyes and ears of the development process, ensuring that every feature behaves as intended before it reaches war-gaming analysts. You will own the detailed documentation of every anomaly you uncover, turning raw observations into clear, repeatable evidence that helps engineers isolate root causes quickly. The work demands intellectual curiosity, disciplined note-taking, and the patience to methodically reproduce issues under varying conditions. You will collaborate closely with engineers and test leadership to define what success looks like for each testing objective. Ultimately, your work will directly influence the stability and reliability of a platform used for high-stakes planning and decision-making.
