Game Level Designer - 3D Unity (Sled Surfers)

Accountabilities:: As Game Level Designer, you will own the creation and optimization of 3D levels while integrating AI into the production process. You will combine creative judgment, technical execution, and data-driven decision-making to deliver engaging player experiences. Your responsibilities will include: Design and implement gameplay mechanics, levels, missions, and player experiences in Unity3D, using AI tools for ideation, rapid prototyping, and content variation. Direct AI agents and coding tools, including large language models and solutions such as Claude Code, to generate scripts, tools, level data, and configurations. Review, test, refine, and validate AI-generated outputs to ensure they meet quality and gameplay standards. Define level structures, sequencing, and difficulty progression, taking ownership of the overall player journey. Balance and maintain levels, gameplay funnels, and progression systems to support engagement and retention. Develop AI-assisted workflows to analyze KPIs, player funnels, and playtest data, identifying issues and testing design hypotheses. Design, monitor, and iterate on live events, using A/B testing and AI-supported analysis to achieve engagement and business objectives. Analyze player reviews, community feedback, and market trends with AI tools, translating insights into actionable design improvements. Create and maintain clear project documentation, including design specifications, briefs, level layouts, and flowcharts, using AI to support drafting while ensuring accuracy. Collaborate with Product Owners, Data Analysts, and Engineers to define requirements, evaluate performance, and deliver design improvements. Participate in design reviews, production milestones, and cross-functional discussions to ensure consistent execution. Explore emerging AI tools and techniques, share effective practices, and contribute to improving the team's design capabilities. Expand the use of AI across the design pipeline, including automated level generation, self-balancing systems, and AI-driven playtesting. Help establish scalable design workflows and systems that may be adopted across additional game development teams. Requirements: The ideal candidate is an experienced 3D mobile game level designer who combines strong creative instincts with a genuine AI-native mindset. You should be comfortable working in a fast-paced free-to-play environment, using data to guide decisions and applying independent judgment to AI-generated content. Key qualifications include: At least 3 years of level design experience in a mobile free-to-play studio, particularly within casual or hybrid-casual games. Hands-on experience designing and building 3D levels in Unity3D. Proven ability to conceptualize, develop, and balance complex level design projects in a fast-paced production environment. Strong understanding of free-to-play game principles, including KPIs, analytics, player funnels, and spreadsheet-based analysis. Demonstrated experience integrating AI tools into real production workflows, including prototyping, level balancing, data analysis, and documentation. Strong critical judgment when working with AI-generated content, knowing when to use, refine, or discard its output. Familiarity with prompting, iterative workflows, and combining multiple AI tools to achieve specific results. Light scripting or experience with AI-assisted coding and rapid development workflows is an advantage. Excellent written and verbal English communication skills, with the ability to explain complex design concepts clearly. Broad knowledge of casual and hybrid-casual mobile games, including current market trends and player expectations. Strong empathy for target audiences and an understanding of their motivations, needs, and gameplay preferences. Additional experience that would be beneficial: At least 3 years of experience working on hybrid-casual or casual puzzle games. Experience building custom AI-assisted tools, agents, or automations to improve design workflows. Familiarity with A/B testing, live operations, and performance analysis. Benefits: Remote flexibility: Fully remote work with support and opportunities to stay connected with the wider team. Team experiences: Annual team trips and global holiday celebrations. Recognition: Birthday and work anniversary gifts, along with additional employee appreciation initiatives. AI development and training: Access to a dedicated AI Lead team providing guidance, training, and support to help employees adopt and use AI tools effectively. Professional growth: Opportunities to expand from hands-on level production into system design, AI orchestration, and scalable content generation. Career progression: Potential pathways toward design leadership, AI Design Lead positions, and cross-title responsibilities. Innovation: Early access to emerging AI tools and the opportunity to influence how new technologies are integrated into game development. Collaborative environment: Support from an experienced people team throughout onboarding and the employee journey.
