About the Role:

We're looking for a Full-Stack Engineer to join the distributed development team and help expand the platform. This role blends backend engineering and frontend development, enabling seamless interaction between the device ecosystem, internal tools, and user-facing applications. You'll be working in a fast-paced, collaborative environment where innovation and precision meet.

Responsibilities:

      Backend (~70%)

• Design and build services and REST/gRPC APIs
• Model data in MongoDB (schemas, indexes, performance) and build messaging flows in RabbitMQ
• Apply event-driven and microservice patterns; define clear service contracts (Protobuf)
• Own availability/performance concerns (HTTP/1.123 semantics, caching, streaming)
• Containerize with Docker, configure Nginx reverse-proxy; contribute to monorepo workflows.

       Frontend (~30%)

• Build and integrate Vue 3 UI (Composition API) for internal/admin/player-facing tools
• Use SSR/SSG (Vike/Vite) where appropriate; manage state (Pinia) and server state (Vue Query)
• Implement UI interactions/animations (GSAP or alternatives) and optimize performance
• Maintain a shared component library and SCSS/Sass styles.

Requirements:

• 5+ years of experience
• Monorepo experience
• Strong production + TypeScript
• Deep understanding of HTTP/1.123
• REST API design/operation (versioning, pagination, auth, rate limiting)
• MongoDB (high proficiency) and RabbitMQ (exchanges, routing, durability, back-pressure)
• Microservices & event-driven architecture in production gRPC + Protocol Buffers for inter-service communication
• Docker (practical) and Nginx (basic+)
• Git, code review, unit/integration testing foundations.
• Production Vue 3 + TypeScript (Composition API)
• Experience with SSR/SSG frameworks (Vike or similar) and Vite
• State management (Pinia) and data-fetching (TanStack Query / Vue Query, Axios)
• Confident with SCSS/Sass, modern CSS, and Web APIs (DOM)
• English - B1 or higher (reading and writing technical documentation)

Nice to have:

• NestJS (baseline production)
• Kubernetes, ClickHouse
• Vitest/Jest, test strategy design
• Bluetooth/BLE exposure (device integration)
• Familiarity with GSAP for complex animations
• Native languages (C/C++/Rust) exposure
• Google Cloud Platform
• Basic cryptography experience (hashes, sym/asym crypto, signatures, certificates, jwts).

The company offers:

• The opportunity to work with a unique, award-winning hardware gaming platform
• A creative and international team focused on innovation and quality
• Flexible remote collaboration within European time zones
• Involvement in cutting-edge device-based game testing where physical and digital gameplay meet
