[Hiring] Senior Unity Engineer @Goodgame Studios

Role Description

Are you ready to be the ultimate performance hero? At Goodgame Studios, we are looking for a Senior Unity Developer (m/f/d) whose job is to make our new mobile F2P title fast, lean, and pleasant to build on. You'll be the one person at GGS who owns performance as a discipline for this title – build time, memory, and runtime – working closely with the Tech Lead and Engineering Manager to ensure millions of players enjoy a flawless, lightning-fast gaming experience.

Whether you want to join us as a permanent employee working full-time remote from anywhere in Germany, or collaborate with us as a Freelancer (within ±3 hours of CET) - we offer the flexibility to suit your lifestyle. If you love digging deep into Unity to make games run optimally, we want you on our team!

Your mission includes:

• Build time performance: Improve local iteration pain points such as domain reloads, asset imports, Addressables builds, and CI.
• Memory optimization: Manage mobile memory ceilings, heap and GC pressure, asset streaming, and texture/mesh budgets.
• Runtime performance: Focus on CPU main thread, GPU and draw calls, physics, and networking. Establish profiling practices, regression detection, and performance gates.
• Agentic engineering practice: Establish workflows using agentic tools and build internal agents for performance regression detection and build pipeline automation.

Heads up: we will ask you to demonstrate your agentic workflow live in the interview. Bring your real setup, your real prompts, your real failures. We're more interested in how you actually work than in a polished demo.

Qualifications

• Senior-level Unity experience, Unity 6 or recent versions, iOS and Android.
• Shipped at least one live mobile game with a significant user base.
• Deep, demonstrable experience with Unity profiling tools (Profiler, Memory Profiler, Frame Debugger, Profile Analyzer) and platform-native tools (Xcode Instruments, Android Studio Profiler, RenderDoc or similar).
• Track record of measurable performance wins you can talk about concretely – numbers, before/after, what you tried that didn't work.
• Comfortable in a solo specialist role: you set the standard, you don't wait to be told what to optimize.
• Highly proficient in English.
• Seeking full-time remote roles (within Germany, valid German visa required) or Freelance opportunities within the German timezone (CET/CEST).

Requirements

• Experience with agentic engineering workflows – whether that's heavy use of coding agents in your own work, or building agentic tooling for engineering teams.
• Experience with Unity's render pipelines (URP in particular), Addressables at scale, IL2CPP build pipelines.
• Experience with live mobile F2P games specifically (live ops cadence, A/B infrastructure, soft launch).
• DOTS/ECS exposure.

Benefits

• Collaborate closely with our 30+ dedicated professionals at Goodgame Studios.
• Employ your initiative and strong communication skills to seamlessly integrate your ideas into our MMO pioneer games.
• Join a team with more than 200 million registered players worldwide and a history of more than €1 billion in revenues.
