• Integrate in‑app purchases, ads, analytics, and live‑ops features.
• Ship builds to iOS and Android stores, ensuring smooth release and update processes.
• Work from detailed technical documentation with minimal supervision, asking the right questions when needed.
• Contribute to a respectful, collaborative team culture—mentoring others where possible.

• Platform Delivery – Comfortable with Xcode (provisioning, code‑signing, TestFlight / App Store Connect, Metal optimization) and Android Studio (Google Play release).
• Backend & Live‑ops – Understanding of client‑server architecture; experience with in‑app purchases, push notifications, analytics, ads, Game Center / Google Play Games integration.
• Production Pipeline – Experience with CI/CD build automation (Jenkins / GitHub Actions), automated testing, and version control (Git or Perforce) with code‑review practices.
• Soft Skills – Upper‑intermediate + English, ability to write clear technical documentation, present solutions, and work productively with multi‑disciplinary teams.

Bonus Points

• Experience working with massive, long‑lived codebases in a live game environment.
• Familiarity with Zenject or other dependency‑injection/entity frameworks.
• Shipped games in the free‑to‑play mobile space.
