Principal C++ Engineer (Factory Simulation)

PRINCIPAL C++ ENGINEER (TOBSPR GAMES)

🕹 Factory simulation game
🧠 Principal
💰 Negotiable
⏰ Full-time
🌎 Remote within Germany 🇩🇪

🦄 Description
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.

🚀 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

📚 Required Skills
• 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

👍 Nice to 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

🍪 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
• Focus days to research or learn new skills
• A yearly team gathering to meet and collaborate in person
• A yearly salary review to keep your pay in line with the market, and an automatic increase of 2% per year
