Principal C++ Engineer (Tobspr Games)

Principal C++ Engineer for a factory simulation game, full-time remote within Germany.

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
