Game Developer (backend)

Snowprint Studios AB

Do you thrive in collaborative teams and want your work to shape what players experience every day? As a Backend Developer at Snowprint, you’ll build the backend systems, infrastructure, and tools that power our games. You’ll work closely with your fellow developers, designers, and other disciplines to create stable, scalable solutions, always with the player experience in mind. At Snowprint Studios, we believe that kindness, collaboration, curiosity, and self-leadership are what make great games possible. We work in small, cross-disciplinary teams where people are trusted to take ownership, share ideas openly, and continuously improve how we build games together. What you’ll be doing You'll bring new game features to life while also supporting the systems, tooling, and infrastructure behind them. The role combines feature development with live operations, giving you the opportunity to work on both player-facing functionality and the technical foundations that keep the game running. You'll take ownership of the technical areas you work on, from planning and implementation to testing and live operations. A normal week might include feature development, playtests, troubleshooting production issues, discussing technical approaches with the team, and improving systems to support future needs as the game evolves. You’ll collaborate closely with your colleagues to shape technical solutions that work well for both the game and the people building it. Is this you? You’re an experienced backend developer who is fluent in Kotlin and/or Java. You’ve worked with live backend services before, and you’re comfortable operating cloud infrastructure (We use AWS). You know how to troubleshoot complex issues in production environments and enjoy the mix of bug-fixing, fine-tuning, and forward-planning that comes with live operations. You communicate clearly, ask questions, and enjoy working through problems with your colleagues. You’re self-directed but collaborative, happy to own your part of a feature while staying connected to the bigger picture. You care about the player experience, and you bring that mindset into technical discussions. Where you’ll work Our Stockholm studio is located in Södermalm, and we work in a hybrid setup. We work from the office on Tuesdays and Fridays to support collaboration and social interaction, while other days offer flexibility depending on where you work best. We provide the setup and tools you need to work comfortably both at home and in the studio.

Fatalist Development AB

We are seeking a highly autonomous, high-output DevOps & AI Engineer to design and build a pioneering AI-assisted system. This solo-developer initiative will automate the complex integration, merging, and migration of game project branches across versions, encompassing both Unreal Engine 5 and our proprietary APEX engine projects. You will be responsible for creating an intelligent system that not only manages Git and Perforce workflows but also integrates seamlessly with Jenkins for robust preflight validation and automated testing. Leveraging advanced LLM-powered agentic workflows, the system will classify, triage, and reliably resolve merge conflicts, moving beyond blind binary merges to intelligently interact with engine APIs and scripting environments. This is a critical role for someone ready to independently build a sophisticated backend agent framework and an intuitive frontend dashboard while leveraging an existing, mature CI/CD infrastructure. What you’ll do Design and Build an AI-Powered Integration System: Architect, develop, and deploy a comprehensive AI-assisted platform that automates game project branch integration across Unreal Engine 5 and APEX. The system will support both Git and Perforce version control and integrate seamlessly with Jenkins-based CI/CD workflows. Develop Intelligent Conflict Resolution: Implement advanced LLM-powered agentic workflows to classify, triage, and resolve merge conflicts. Focus on deep contextual understanding, multi-pass investigation, and intelligent decision-making rather than relying on blind binary merges. Engine and Scripting Automation: Leverage native Python scripting and engine APIs to interact directly with Unreal Engine, automate tasks such as Blueprint recompilation and contract-change updates, and extend these capabilities to proprietary engines such as APEX. Full-Stack Development and Workflow Orchestration: Independently build both the backend agent framework and an internal, project-specific frontend dashboard. Design and manage complex state machines for "Paused Integration" workflows, enabling human-in-the-loop intervention and continuous learning through self-reflection mechanisms based on human resolutions. Define and Track Success Metrics: Establish, monitor, and refine key performance indicators (KPIs) that measure AI effectiveness, including Attempt Rate, Escalation Rate, and Rollback Rate, ensuring continuous improvement, operational efficiency, and system reliability. Who you are: Version Control & CI/CD Mastery: Deep expertise in both Perforce and Git, with a strong understanding of their distinct workflows and underlying models, as well as hands-on experience designing and authoring Jenkins pipelines for robust CI/CD processes within mature development infrastructures. Game Engine & Asset Pipeline Knowledge: Working knowledge of Unreal Engine 5 project structures and asset pipelines, including a strong understanding of the challenges associated with merging game-specific assets such as .uasset files, Blueprints, and other engine-generated content. Applied AI/ML Practitioner: Proven ability to build practical applications using LLMs through APIs, including prompt engineering, context engineering, agentic frameworks, and retrieval-augmented generation (RAG). Experience applying these techniques to areas such as code-diff analysis, semantic understanding, and automated conflict resolution, with a focus on orchestration rather than model training. Polyglot Developer & Systems Integrator: Proficient in Python, C# for engine tooling, and C++, with full-stack web development experience (e.g., React and Node.js) for internal dashboard development. Skilled at orchestrating complex systems and integrations across multiple platforms and APIs, including version control systems, CI/CD tools, Jira, and Slack. Autonomous & Strategic Thinker: A highly self-directed professional capable of independently driving complex projects, strategically leveraging AI orchestration to delegate work to specialized agent sub-systems, and designing resilient architectures with robust state management. Game Industry Experience: Demonstrated experience in the game industry or engine development, with a strong appreciation for the unique technical and workflow complexities of game production.
