UserWise Services is hiring a Senior Unity Engineer (Mobile Games)

About the Role

Shape the future of mobile gaming as a Senior Unity Engineer on a team dedicated to building and evolving live-service titles. You'll develop core gameplay systems, user interfaces, and backend-connected features using Unity and C#, translating design concepts into responsive, scalable code that reaches players worldwide.

What You’ll Do

  • Design and implement gameplay mechanics, progression systems, and event-driven content for mobile F2P titles
  • Build reusable, modular systems that support frequent content updates and live operations
  • Integrate animations, UI flows, and visual feedback to enhance player engagement
  • Optimize client performance, memory footprint, and load times across a range of mobile hardware
  • Collaborate with designers, artists, and producers to ship features efficiently
  • Diagnose and resolve technical issues affecting gameplay stability and user experience
  • Contribute to code quality through peer reviews and shared engineering standards

What We’re Looking For

  • At least 5 years in game development, with 3+ years focused on Unity and C#
  • Proven track record shipping commercial mobile games, especially free-to-play titles
  • Deep familiarity with Unity’s architecture, including scripting, UI, and asset pipelines
  • Experience tuning game performance and build size for mobile platforms
  • Strong command of Git and collaborative development workflows
  • Clear communication skills in English, essential for working with a distributed team

Nice to Have

  • Integration experience with backend APIs, analytics, or telemetry platforms
  • Knowledge of modern software design patterns and architecture
  • Hands-on work with physics, particle systems, or animation tools
  • Experience in cross-functional teams balancing creative and technical goals

Why This Role Stands Out

You’ll work in a compact, high-impact team where ownership and initiative drive results. With full remote flexibility and team members across Eastern Europe, you’ll enjoy autonomy, rapid iteration cycles, and direct visibility into how players interact with your work. Career growth, performance feedback, and technical mentorship are built into the rhythm of our development process.
