Break larger goals into tasks, estimate timelines, and implement high-quality solutions.
Communicate frequently, updating the team on progress, risks, and sharing ideas.
Uphold quality through architecture/code reviews, testing, and feedback.
Improve stability by investigating live issues, fixing bugs, profiling, and managing tech debt.

SKILLS TO CREATE THRILLS

Extensive software development experience in Unity and C#.
Strong architectural knowledge with the ability to quickly adapt to new codebases.
Experience creating and supporting tools in game development, along with mobile development expertise and best practices.
Excellent communication skills, both verbal and written, with a proven ability to collaborate effectively across design, art, and multidisciplinary teams.
You're quick to learn and adapt to new workflows and tools, and you're open to leveraging AI technology to enhance your daily work.
You are keen to grow and develop yourself and you are good at giving and receiving feedback.
