Job summary

tobspr Games is seeking a Senior Networking Engineer to build co-op multiplayer for our upcoming factory game in Unreal Engine 5. You will join a small but growing team and collaborate closely with the Principal C++ Engineer to keep the simulation in sync across players while optimizing bandwidth and latency.

• Hands-on experience with replication system (replication graph, dormancy), RPCs and network relevancy.
• Understanding of deterministic lockstep or input-based networking.
• Experience with Steam networking or online subsystems.
• Permanent role: broad Unreal experience outside networking.

Responsibilities

• Design and build co-op networking for the game, from session flow to replication.
• Work with the Principal C++ Engineer so the sim stays in sync between players, without flooding bandwidth or introducing excessive delays
• Profile and fix network performance, latency, and desync issues

Job description

About the role

We\'re looking for a Senior level Networking Engineer to build co-op multiplayer for our next factory game in Unreal Engine 5.

Co-op sits on top of a large, deterministic factory simulation. Replication has to deal with hundreds of thousands of machines, not just a handful of characters.

Ye\'ll join a new game team as one of its first engineers, working closely with the Principal C++ Engineer and the Engineering Team Lead.

We\'re open to two setups: a 6 to 12 month freelance contract focused on networking, or a permanent role where networking is your speciality and you work as a generalist the rest of the time.

Your responsibilities

• Design and build co-op networking for the game, from session flow to replication


• Work with the Principal C++ Engineer so the sim stays in sync between players, without flooding bandwidth or introducing excessive delays


• Profile and fix network performance, latency, and desync issues


• Set up tooling to test multiplayer early and often


• Document and train the team in the networking model, so that Engineers and Designers can build features on it

About you

You will likely have:

• 1+ shipped title where you worked on networking in Unreal Engine 4 or 5, in C++


• Hands-on experience with Unreal\'s replication system (including replication graph, dormancy), RPCs, and network relevancy


• Good judgement on what goes through Unreal replication and what the deterministic sim handles


• Experience with deterministic lockstep or input-based networking, or you can show how you would approach it

In addition, you may have:

• Experience with Steam networking or online subsystems


• Experience shipping co-op in a building, survival or factory game


• Experimented with the new UE replication system, Iris


• For the permanent role: broad Unreal experience outside networking

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
