We are looking for a talented and passionate NPC Behaviour Engineer to help create believable, responsive and engaging AI behaviours for video game projects, both for Flix's own proprietary projects and high-profile clients.

You will work closely with Design, Engineering, Animation and other disciplines to develop AI systems and behaviours that bring game worlds and their characters to life. We are looking for someone who is passionate about video games, enjoys solving complex problems and is excited by the challenge of creating AI that makes players feel like they are interacting with a living world.

• Design, implement and iterate NPC AI behaviours and systems, from initial prototype through to production-ready implementation.
• Develop systems for NPC decision-making, navigation, perception, combat, reactions and other gameplay behaviours.
• Work closely with Designers and other disciplines to translate gameplay requirements into robust and engaging AI systems.
• Debug, profile and optimise AI systems, identifying and resolving issues that affect behaviour, performance or player experience.
• Playtest and iterate AI behaviours to ensure they are fun, believable, readable and appropriate to the intended gameplay experience.
• Contribute to the development of reusable AI tools and systems that can support multiple features and projects.
