We build immersive stories, mobile games, and spatial experiences that stand out and deeply engage users. To help us push the boundaries of mobile interactive experiences, we are looking for a passionate Unity Gameplay Developer with a strong focus on iOS and Android platforms to join our agile team.

Your Responsibilities

• Gameplay Engineering: Develop, implement, and iterate on core gameplay mechanics, interactive systems, and game logic for mobile platforms using Unity3D and C#.
• Mobile Optimization: Ensure our mobile experiences run flawlessly. You will profile, debug, and optimize game performance, memory usage, and battery consumption across a wide spectrum of iOS and Android devices.
• Platform Integration: Handle mobile-specific implementations, including touch and gesture controls, mobile UI scaling, and native device feature integration.
• Cross-functional Collaboration: Work hand-in-hand with our UX/UI designers, 3D artists, and creative directors to ensure the technical feasibility of creative concepts and translate them into a polished mobile experience.

• Languages: German language skills are a plus.

This role is remote-friendly. Most of your work happens wherever you're most productive, in the office or at home. What we do need is the flexibility to join us in the office for project-related tests and setups, depending on each project's scope. That's why being based in the Hamburg metropolitan region is a must.

Why us?

• Bold Innovation: “We've always done it this way” is not part of our mindset. We experiment, learn, and grow together.
• Creative Freedom: Your ideas matter. The best innovations happen when people are free to think differently.
• Diversity & Team Spirit: We value diverse identities, backgrounds, and perspectives as the foundation of innovation. We're committed to creating an inclusive environment where everyone can thrive authentically.

What makes us special

• A state-of-the-art tech stack and access to the latest XR devices
• True work-life integration with flexible hours and remote/office options
• A growth-oriented environment with mentoring, feedback, and challenging projects
• Hands-on involvement in all project phases - from concept to launch
• Flat hierarchies, open communication, and a strong team spirit
• International projects and a global network of partners and clients
• A team that supports each other and celebrates success together

Here's the process

• First chat: if it looks like a match, we'll reach out within 10 business days for a quick intro call (about 30 min).
• Deep dive: we get into the details: Your projects, how you work, what you're looking for. About 60 min, remote or at our Hamburg studio.
• A small pre-employment assessment along the way.
• Meet some of the team - an honest conversation to see if we click.
