About the company

Playrix is one of the most successful mobile game development companies in the world. Our games have been installed 2.3 billion times (that's a third of the world's population!). We are transforming how our hit mobile games operate post‑release. Our core mission is to architect and build a single, highly reliable, and unified LiveOps Platform that manages every operational cycle — from A/B tests and in‑game events to balance changes and content delivery across all titles. This platform is the future central nervous system for our game operations.

Hands‑On Tech Lead

— an engineer who is ready to design the system, drive development with their own high‑quality code, and skillfully lead a team of 3–5 engineers. Success requires strong leadership in complex stakeholder management, as this centralized platform impacts all our game studios, product owners, and business analysts.

We handle everything related to operational flexibility: managing events, offers, experimentation, game balance, configurations, schedules, and feature rollout. The team is responsible for delivering the core platform and tools that allow product teams to rapidly iterate, manage the game economy, and run complex experiments efficiently. You will collaborate closely with game designers, producers, analysts, and ML/AI engineers to define requirements and deliver the infrastructure that enables fast, predictable operations.

Architectural Leadership

Define and own the technical architecture of the LiveOps Platform, ensuring maximum reliability, scalability, and integration capability across all game projects.

Write high‑quality, high‑performance code, especially for core services and integrations. Build tools and services for centralized management of A/B tests, configurations, feature flags, game balance, and content delivery.

Process Automation

Automate the end‑to‑end LiveOps process chain to reduce manual effort, increase the speed of experiments, and provide transparent data flow for product teams.

Engineering Mentorship

Lead the engineering team (3–5 people) in technical best practices, code quality (reviews, design reviews), and effective engineering processes.

Manage technical debt, communicate complex trade‑offs, and align the platform roadmap with the demanding needs of multiple game studios and business stakeholders.
