Founding Real-Time Systems Engineer - Games - B2B

Job Location: remote from Romania Budget: 30-40 euro/h Recruitment process: HR discussion Technical interview Role description: Our client is a new company building technology that syncs real-world live sporting event data (motion and positional data) with gaming environments in real time, so players can experience live moments as they unfold within the game. The initial focus is sport and Roblox, with plans to expand into other entertainment and gaming platforms down the line. You will lead the development of the real-time processing, networking and delivery architecture. You will work with high-frequency live motion data, transforming and optimising it before delivering it reliably into gaming environments. The challenge spans real-time state, networking, data processing, interpolation, buffering and resilience. This is a hands-on founding role with future ownership. You'll help shape the technical direction of the product as well as build it. As the company grows, you will help turn the first implementation into reusable infrastructure capable of supporting different types of data inputs and platform outputs. What you'll work on: Support the design of LIVESYNC's real-time processing architecture Build the systems to ingest and process high-frequency live event data Build the systems for validation, transformation, interpolation and synchronisation Build the networking and delivery layer between live data providers and games Design for latency, reliability, failure recovery and scale Develop secure, observable cloud infrastructure Work closely with our games engineer to optimise the complete live event-to-game system Design the architecture so new data types and platforms can be added efficiently Contribute to technical decisions, documentation and future engineering hires What we're looking for: You are an experienced engineer who has built real-time systems where timing, state and reliability matter. You should have strong experience across several of the following: Real-time or distributed systems Multiplayer or game networking WebSockets and high-frequency data AWS or equivalent cloud infrastructure State synchronisation, buffering and interpolation Backend development using technologies such as TypeScript, Go, Rust or C++ Performance, monitoring and production reliability Experience with game server infrastructure, motion capture, sports tracking, telemetry, Photon or other live streaming systems would be particularly valuable. The kind of person we're looking for: You should enjoy difficult technical problems, be comfortable making decisions with incomplete information and be willing to challenge our assumptions when there is a better solution. You will move between architecture and hands-on engineering, work directly with founders and technical partners and take genuine ownership of the systems you build. We want someone interested in helping create not just the first architecture, but the engineering organisation that develops around it. Over time, this role has the potential to grow from building our fi rst real-time architecture into owning multi-sport, multi-platform infrastructure and technical leadership. Quali fi cations: Strong Systems Engineering skills, including designing and implementing scalable, real-time backend services. Experience with Systems Design, covering architecture for low-latency event processing and high-availability services. Proficiency in Troubleshooting complex production issues, performance bottlenecks, and reliability problems in distributed systems. Hands-on System Administration and Technical Support skills for managing servers, observability tooling, and deployment environments. Experience with real-time networking (e.g., WebSockets, UDP), concurrency, and event-driven architectures. Comfort with at least one modern programming language commonly used in backend game or real-time systems (e.g., C++, Go, Rust, Java, or similar). Familiarity with cloud platforms and containerization/orchestration tools (e.g., Kubernetes, Docker, major cloud providers). Ability to work collaboratively in a small founding team, take ownership of systems, and operate in a fast-evolving startup environment. Prior experience in gaming, live events, or real-time streaming systems is highly beneficial.
