PROJECT: We are building 4connection – a modern, feature-rich messenger combining group messaging, interest-based communities and serious dating/matching features. Think Telegram meets thoughtful matchmaking – with accessibility, youth protection and strong encryption built in from the start. The Rust backend handles message routing, user matching algorithms, group management, API and the web presence. This is a client-commissioned project with a clear product vision.

REQUIREMENTS: 1+ years of experience in C, C++ or another systems-level language. Understanding of memory management (stack vs. heap, pointers, ownership concepts). Basic knowledge of network programming (TCP/IP, WebSockets, HTTP). Interest in learning Rust – we will train you, supported by AI-assisted development with Claude. Clean, readable, maintainable code is non-negotiable. Experience with Git and Linux. Good English skills (reading and writing).

NICE TO HAVE: Any Rust experience (even personal projects). Experience with async programming (Tokio, epoll, io_uring). Experience with matching algorithms or recommendation systems. Knowledge of Firebase integration. Experience with accessibility standards or youth protection regulations.

RESPONSIBILITIES: Implementing the backend architecture under direct guidance of the technical lead. Building message routing, group management and user matching systems. Implementing interest-based and dating match algorithms. Building the persistence layer and REST/WebSocket API. Integrating with Firebase and third-party services. Collaborating closely with Android and iOS developers on API design. Writing testable, documented code that any equivalent specialist can take over immediately.

WE OFFER: Fully remote work. A small, focused core team of 4 developers – no corporate overhead. Direct collaboration with an experienced technical lead who mentors rather than manages. AI-assisted development with Claude as a fixed part of the workflow. The chance to shape a backend architecture from the ground up. Clients will be released as open source – you are building something visible. Fair compensation, long-term collaboration. Nextcloud and Redmine for collaboration – open-source tooling.

Tech Stack: Rust, Tokio, Axum/Actix-Web, Firebase, Linux, Git, Redmine, Nextcloud

We are a "people first" company, which affects every decision we make - from who we hire, to how we treat each other, to how we view and serve our players.  We're committed to an A+ creative culture where every member of the  team can find personal fulfillment in the incomparable art of making video games.

THE ROLE

We are looking for an amazing Lead Platform Engineer with a varied background in building and maintaining services relied upon by the game and its surrounding infrastructure. Our first title is an ambitious 3rd person smart shooter with unique elements. This is not your everyday shooter! 

This role will manage our game platform and work closely with Gameplay Engineering, LiveOps, Devops, and Analytics to contribute to a robust, scalable platform encompassing authentication, social features, matchmaking, session and server instance management, and more.

IN THIS ROLE, YOU WILL

• Lead the development and evolution of platform systems built on Pragma to support live environments.
• Own platform execution and technical direction in close partnership with gameplay, backend, and production teams.
• Design, implement, and operate server infrastructure using Hathora to support session-based multiplayer gameplay.
• Build and maintain tools and services that support development workflows, live operations, and reliability.
• Work closely with gameplay engineers to ensure reliable integration between game systems and platform services.
• Define, track, and respond to operational metrics, helping establish effective live service monitoring practices.
• Make pragmatic technical decisions, balancing player experience, delivery timelines, and operational constraints.
• Provide timelines and risk assessments to Production, proactively identifying dependencies and mitigation plans.
• Set technical standards through example, code reviews, and shared ownership.
• Manage Internal and external platform resources. 
• Manage platform (Pragma) and server architecture (Hathora) relationships. 

 EXPERIENCE AND SKILLS WE LOOK FOR:

• 6+ years of backend or platform engineering experience, preferably in games or real-time services.
• Experience shipping and operating a session-based live service title.
• Strong understanding of web API design, service contracts, and backend best practices.
• Experience with Kotlin and/or Java is a plus.
• Comfortable integrating backend services with Unreal Engine–based clients.
• Collaborates effectively with cross-discipline, fully remote teams.
• Able to work independently and take initiative in a fast-moving, flexible environment.
• Startup experience is a plus.
• Comfortable working across multiple time zones. (Team based globally from EU-Central to US-West)
• Passionate about building reliable systems that support great gameplay.

WHY WORK WITH US?

• We are committed to making great games with our first title Last Flag coming out soon. 
• You can work fully remote
• We have a sense of humor and while we take the work seriously, we take ourselves less so.
• You'll be hard-pressed to find a happier group of people to work alongside.
• More about the project can be explained under NDA
