Principal C++ Engineer

About the role

We're looking for a Principal C++ Engineer to own the factory simulation of our next game. The game is built in Unreal Engine 5 , but the simulation will be self-contained and written in raw C++.

Players will place hundreds of thousands of machines, belts, pipes, and more across a large world, and every one of them has to deterministically update on every player's device in a co-op session.

You'll design that simulation module from the ground up as one of the first engineers on a new game team , working closely with the Engineering Team Lead and the Game Design department.

Your responsibilities

• Design and build a deterministic factory simulation that scales to hundreds of thousands of player-placed buildings
• Own the sim architecture: data layout, tick model, threading, and serialisation format
• Work with the Networking Engineer so the sim and co-op are designed together, not bolted on later
• Set and meet the CPU performance budget for the sim on our minimum specification target
• Review code and mentor other engineers on C++ and architecture

About you

You will likely have:

• Experience in professional C++ environments where you have architected, implemented, and maintained performant modules which are built on by other engineers, and lived with the consequences of your design choices
• Deep knowledge of data-oriented design, multithreading, and performance, including CPU profiling and applying algorithmic complexity-based analysis to select the right data structures
• Built a deterministic or lockstep system, or can show how you'd approach one
• A track record of mentoring engineers and making architectural decisions in writing that others could follow and challenge

In addition, you may have:

• 2+ shipped game titles
• Worked on a factory, automation or simulation-heavy game
• Worked in Unreal Engine, especially with Mass Entity or a custom ECS in Unreal

If you match most of this and the problem excites you, please apply.

What we offer

• Fully Remote: We employ directly inside Germany
• Flexible working hours!
• Paid overtime, on the rare occasions it happens
• A hardware budget to ensure you have the ergonomic setup and hardware you need to work comfortably
• A monthly personal growth allowance for courses, books or other learning material
