  • Write text-based scripts that define the behavior tree for AI in the game, using a proprietary scripting language
  • Troubleshoot, debug, and fix AI behavior and performances
  • Tune and maintain large amounts of content and systems

  • Technically proficient; able to learn and utilize complex systems and toolchains to create gameplay experiences; able to suggest workflow improvements
  • Ability to analyze gameplay experiences, identify problems, and generate solutions
  • Excellent written and verbal communication skills

So you don’t meet every requirement listed in this job description? Do you think your experience level is not where it needs to be? Studies show that members of certain underrepresented groups are less likely to apply to jobs unless they believe they meet every single qualification. Bungie is focused on building a diverse, inclusive, and equitable workplace. If you’re interested in this position but your past experience doesn’t line up perfectly with every qualification in the job description, we want you to apply anyway. The right role for you may be right around the corner!

Most Bungie full-time employees will adopt a digital first approach allowing remote work in Bungie approved locations (outside of positions identified as 100% onsite in Bellevue/Seattle, or individuals preferring a hybrid/flex environment). Prospective full-time employees who are located outside of a Bungie approved state or province will need to establish residency in an approved state or province within 45 days of their start date. Contractors will follow a digital first approach adhering to the location guidelines agreed upon by our third-party employer/vendor and Bungie. Bungie’s remote policy is subject to change at the company’s discretion.
