Job description

The role

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 and 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!

In this role you'll join Goodgame Studios – self-published MMO strategy titles, 200M+ registered players, €1B+ in lifetime revenue, part of Stillfront Group, one of Europe's leading game publishers.

Your mission

Build time performance. Local iteration is our biggest pain point right now. Domain reloads, asset imports, Addressables builds, CI – all of it is fair game. We expect measurable improvements to the day-to-day developer loop.
Memory optimization. Mobile memory ceilings, managed heap and GC pressure, asset streaming, texture and mesh budgets. We have device targets and budgets; you'll own keeping us inside them.
Runtime performance. CPU main thread, GPU and draw calls, physics, networking – wherever the frame budget is being spent badly. You'll establish profiling practice, regression detection, and performance gates that survive past launch into live ops.
Agentic engineering practice. We want to establish agentic workflows as a real part of how this team works – both using agentic tools (Claude Code, Cursor, Copilot agents, similar) for day-to-day engineering, and building internal agents for things like perf regression detection and build pipeline automation. If you've done this before, we want to learn from you. If you haven't but you're hungry to, that works too.
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.

What you bring

Senior-level Unity experience, Unity 6 or recent versions, iOS and Android
Shipped at least one live mobile game with a significant user base. This is a hard requirement. We need someone who has lived through the realities of low-end Android, store certification, live ops, and the gap between "works on my device" and "works for a million players."
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).

Nice to have

Experience with agentic engineering workflows – whether that's heavy use of coding agents in your own work, or building agentic tooling for engineering teams. This is a real differentiator for us.
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

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 with more than 200 million registered players worldwide and a history of more than 1bn € in revenues. If you're ready to take on this challenge and thrive in a high-target environment, we want you on our team!
