Senior Backend C++ Developer (Framework Team)

About the role

Scorewarrior is a game developer and publisher based in Limassol, Cyprus. The company focuses on the 4X strategy genre, with an ambitious goal to grow its hit game, Total Battle, to become the No.1 strategy game in the world. Our team consists of 200+ passionate, talented, self-driven, and continually developing professionals who love making high-quality games.

Our product: We are currently working on Total Battle — an MMO 4X strategy game with a deep political system and lots of player interaction. Players take on the role of a commander and need to develop their city, forge alliances, fight against monsters, and conquer other players. We're constantly developing new game mechanics, and the project is continuing to grow.

We are looking for a Senior Backend Developer to join the Framework Team building tools used by fellow engineers and powering game services across the company. You will work with modern C++ (17/20), asynchronous systems, network communications (S2S), high-load services, and distributed architectures.

WHAT DO WE DO:

- Design and develop core SDK/framework modules with clean abstractions to enable simple, fast, and high-quality game logic development.

- Gather requirements and design APIs, protocols, and service-to-service interaction contracts.

- Build asynchronous and multithreaded code with high performance in mind.

- Work with S2S communications: idempotency, transactions, and guaranteed delivery in distributed systems.

- Design and evolve ORM and data persistence layers (PostgreSQL, Redis).

- Ensure scalability, stability, and fault tolerance of backend services.

- Work with legacy code—simplify, refactor, and increase reliability without downtime or production risks.

- Implement observability: metrics, logs, tracing.

- Improve developer tools and DevEx — CMake, Conan, Python tooling, CI/CD scripts, Docker.

- Participate in code reviews, architectural discussions, mentoring, and R&D exploration.

WHAT WE EXPECT:

- Ability to gather requirements, design solutions, break down work, and deliver to production independently.

- 3+ years of backend development experience on a statically typed language under Linux.

- 3+ years of commercial experience with C++17/20.

- Strong knowledge of asynchrony and multithreading (threads, futures, coroutines, atomics).

- Understanding of network communication (REST/RPC (gRPC), HTTP, WebSocket, TCP).

- Hands-on experience with PostgreSQL (DDL/DML, transactions, indexes, migrations).

- Solid software design skills: Software Design, SOLID, Clean Code, IoC/DI, composition, GoF patterns.

- Experience working with distributed and high-load systems.

- Understanding of System Design: scaling, degradation, caching, SLA/SLO/SLI.

- Experience with CI/CD, containers, and build systems (CMake, Docker, Jenkins/GitLab).
