🚀 About the Role

We are hiring a Lead Unity Programmer to own the technical foundation of a mobile game from early development through global launch and live operations.

This is a hands-on leadership role for someone who has shipped real mobile games, understands mobile constraints deeply, and is comfortable taking full responsibility for technical decisions in a live production environment.

You will work closely with the Game Designer and Artists in a small, high-ownership team where code quality, performance, and stability matter.


🧠 Responsibilities

  • Own the entire Unity codebase and technical architecture
  • Design and implement core game systems, including:
  • Gameplay framework & state management
  • Save / Load systems with update-safe data migration
  • Offline progression & idle mechanics
  • Event-driven and data-driven systems
  • Profile and optimize performance on real mobile devices:
  • Memory usage & asset footprint
  • GC allocations
  • CPU/GPU load
  • Battery impact
  • Handle mobile-specific lifecycle edge cases:
  • App backgrounding & resume
  • OS low-memory kills
  • Force-close and interrupted sessions
  • Ensure save data integrity across crashes, updates, and reinstalls
  • Design systems resilient to partial saves, corrupted data, and crashes
  • Integrate and manage mobile SDKs:
  • Ads, Analytics, IAP, Notifications
  • Prepare the codebase for live operations:
  • Hotfixes and rapid iterations
  • Analytics-driven tuning
  • Debugging via logs and crash reports
  • Design client logic with anti-cheat and exploit prevention in mind:
  • Time manipulation
  • Offline reward abuse
  • Save file tampering
  • Define coding standards and perform code reviews
  • Collaborate closely with:
  • Game Designer (feasibility, iteration, balance)
  • Artists (asset pipelines, performance constraints)
  • Prepare and support App Store & Google Play releases


✅ Requirements

  • 5+ years of Unity experience, with strong C# skills
  • At least one shipped mobile game on Google Play or App Store
  • Proven experience building a Unity project from scratch
  • Unity execution order & lifecycle
  • Serialization pitfalls and versioning
  • ScriptableObject lifecycle
  • Differences between Mono and IL2CPP
  • Hands-on experience with:
  • Unity Profiler
  • Memory Profiler
  • Frame Debugger
  • Proven ability to optimize:
  • GC allocations
  • Startup time
  • Memory usage
  • Build size
  • Experience handling:
  • Android Gradle builds
  • iOS Xcode signing & provisioning
  • Store submission and review cycles
  • Comfortable working in a small team with full technical ownership
  • Clear written and verbal communication in English


⭐ Nice to Have (Strong Signals)

  • Experience with idle / tycoon / simulation games
  • Familiarity with Unity Gaming Services
  • Experience with server-validated or anti-cheat logic
  • Experience maintaining games post-launch
  • Prior experience as Senior or Lead Unity Engineer


💡 What We Offer

  • High technical ownership and autonomy
  • Small team, fast decisions, no bureaucracy
  • Long-term collaboration potential
  • Competitive compensation based on experience
  • Opportunity to build the technical foundation of a growing studio


🔥 Important Note

This is not a task-only coding role.

We are looking for someone who takes full responsibility for performance, stability, and technical trade-offs in a live mobile game.
