Senior Backend Developer (Framework Team)

We are Scorewarrior - a "Great Place to Work" (officially!), with a 99% employee satisfaction rate. We are financially independent, highly profitable, and proud to have never made redundancies — a testament to our stability, culture, and long-term vision.

Our flagship title, Total Battle, is a top-10 mobile 4X strategy game that has increased it's revenue by more than 25 times over the past five years, with the mission to excite and unite over one million players on a daily basis.

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).
• Familiarity with testing and performance tools (GTest, Valgrind, Perf, Sanitizers).

NICE TO HAVE

• Experience with Kafka / RabbitMQ / NATS and event-driven architectures.
• Ability to build CLI tools in Python.
• Understanding of CAP/PACELC, eventual consistency, and distributed transactions (Saga).
• R&D experience and interest in code generation, scripting engines, and AI tools that accelerate development.
• Basic knowledge of DevOps and Kubernetes.

WHAT WE USE

• No bureaucracy approach: engineers make the technical decisions that shape the product.
• Modern C++20, Boost.Asio/Beast, and CMake for high-performance backend development.
• PostgreSQL, Redis, and Google Spanner for scalable data storage.
• Conan, Docker, and Python tools to streamline development.
• GitLab CI, TeamCity, and Grafana for CI/CD and full observability.
• Freedom to introduce new approaches: codegen, observability tools, AI-based development accelerators — anything that truly boosts the speed and quality of delivering game features.

WHAT WE OFFER

• The best team in the world!
• An excellent remuneration package, including a 13th salary.
• Relocation package for you and your family to Cyprus (Limassol).
• A modern and sunny office close to the sea.
• Private health insurance for you and your family members.
• A monthly pre-school, school, and university allowance for employees' children.
• Lunch compensation and a sports and fitness allowance.
• Personal development opportunities paid for by the company: professional and language courses, books, etc.
• Bonuses for outstanding results, years worked, getting married, and the birth of a child.
• Friendly monthly office parties and epic, annual offsite company birthday and Christmas parties.
