Job Description

Senior Unity Game Developer

Excel at the intersection of client engineering and cloud-driven, multiplayer systems to build the future of AI-powered storytelling games.

Full-time, Remote.

About Storycraft

Storycraft is an AI-powered, mobile-first social sandbox where players don't just play stories—they build them. Think Minecraft meets The Sims meets Wattpad: a new genre of creative, social storytelling where AI helps players bring their imagination to life.

Backed by top-tier investors who have invested in Open AI, Unity, Supercell and others, we're building a platform that reimagines storytelling as play—combining intuitive creation tools, emotionally expressive characters, and collaborative world-building.

The Role

We're hiring a Senior Unity Game Developer who excels at the intersection of client engineering and cloud-driven, multiplayer systems. You'll design and build features for the Unity front end that power Storycraft's mobile experience, and stretch into our Go backend (following existing patterns) to own features end-to-end. From buttery-smooth rendering to cloud-native streamed gameplay, you'll ensure players feel the magic—instantly and reliably.

This is a senior individual contributor engineering role. You'll lead through hands-on coding, collaborating closely with another senior Unity developer, backend, product, and design teams to deliver performant, testable, and maintainable features. The ideal candidate thinks like a full-stack engineer, loves high-quality codebases, and understands the nuances of a networked multiplayer game on mobile.

What You'll Do

• Prototype and ship new gameplay features that showcase Storycraft's AI-powered creation tools and social systems
• Evolve Storycraft's Unity client: design and implement new features, test and optimize performance, and integrate with mobile platforms (iOS & Android)
• Integrate features with our websocket-based multiplayer layer, ensuring low-latency and state synchronization with the Go backend
• Collaborate with our backend engineer to design API contracts and occasionally contribute your own Go code using our existing frameworks and patterns
• Optimize rendering, memory, and bandwidth for cloud-streamed play and AI-driven features
• Write testable, modular C# code and introduce/maintain automated tests (unit, integration, play-mode) in Unity
• Mentor peers through thoughtful code reviews and technical guidance; champion engineering best practices
• Monitor live metrics, debug production issues, and deliver rapid fixes without sacrificing code quality

You Bring

• 5+ years professional experience developing games in Unity/C#, including at least one shipped mobile or cross-platform live service game
• AI-fluent or AI-literate: excited to share how AI tools can accelerate your development workflows and learn to integrate gameplay with AI technology
• Strong understanding of networked gameplay architectures (authoritative server, client prediction, reconciliation, websockets or similar)
• Experience collaborating with backend teams and contributing full-stack. You can read and write basic server-side code using existing frameworks and patterns
• Strong grasp of software architecture, design patterns, and automated testing strategies in Unity
• Proven track record optimizing performance, memory, and build size for mobile devices and/or streamed game clients
• Familiarity with CI/CD pipelines, and modern DevOps practices
• Startup-ready: autonomous, adaptable, bias to action, and energized by rapid iteration

Bonus Points For

• Based in Canada and/or ET timezone
• Demonstrated expertise in AI-assisted programming workflows
• Prior startup experience or shipping a complete game on your own
• Prior experience integrating ECS-style, data-oriented architectures in Unity
• Experience with integrating LLMs or Diffusion models in production and/or assessing AI performance through evals
• Experience with the Go programming language
• Passion for sandbox, creative, or social storytelling games—and a personal creative practice

What It Means to Build at Storycraft

This isn't just a job—it's a rare opportunity to co-create a new category of game at the intersection of storytelling, AI, and player expression. We're a lean, high-trust team building fast, learning constantly, and thinking long-term. That means:

• You'll be at the vanguard of AI. Storycraft embraces modern AI technology as a core part of its game features, development team processes, and company operations.
• You'll be scrappy and smart. We use AI, feedback loops, and focused iteration to do more with less.
• You'll have real ownership. You won't be "supporting" the product—you'll be shaping it every day.
• You'll grow faster than anywhere else. This is a career-defining opportunity to learn, stretch, and contribute at a level few companies allow.
• You'll have equity with real upside. We're building something ambitious. If we win, you win.
• You'll make an impact that matters. Players already say Storycraft "feels like magic." You'll help scale that magic into something unforgettable.

We're not looking for passengers—we're looking for builders, owners, and technical leaders who want to leave their mark.

How to apply

Write a short introductory email and tell us about yourself. Attach your resume and portfolio (or link to them), and send them to jobs@storycraft.gg - we'll reply to every application we receive.

Your email should include links to games you've developed and shipped. We love to see code samples, so please send recent examples of code you are proud of. If your experience isn't exactly right but you still think you should work with us, go for it, you never know!
