Company Description

Gabsee is a gaming startup currently working on the Stories One title. We want to build virtual friendships between people that will be like the ones in real life: strong, lasting and with shared memories worth remembering.

We are developing Stories One, a Social Adventure game for building tight-knit communities. More than a game, it is a whole world where you will experience thrilling adventures with a persistent group of players, decide and write the story of your community. You will be living the Next-Gen of TV shows: Don't just watch it... Be a part of it together!

We gather players in towns of 1000 people, where they play as high-schoolers in the 80s investigating strange events that occur in the region to save their town from catastrophe.

Our values

  • REAL VALUE: We focus on building real value, not perceived one

  • SMART EXPLORER: We are smart explorers and we want to be the first

  • TEAM FIRST: We are all actively dedicated to making Gabsee the dream team

  • EMPATHY: We are extraordinarily empathetic and candid with each other

At Gabsee, we are committed to creating a workspace where everyone feels safe, respected and valued. We are dedicated to building a culturally diverse team and strongly encourage applications from people of marginalized genders or race.

Job Description


Gabsee is looking for a talented network programmer who takes ownership of players' online experience. You care about providing our players with the ultimate multiplayer experience they deserve.

For Stories One, we developed a networking stack to run the game on multiple interconnected authoritative game servers, serving up to a hundred concurrent users synchronized in real time.

  • Persistent focus on optimization for the network layer (bandwidth, CPU, memory)


  • 3y+ experience in game programming using C# and/or C++

  • Shipped at least one game working on networking part, in client/server scenario

  • Good knowledge of game networking concepts (replication, prediction, lag compensation, etc.)

  • Knowledge of low-level networking (Sockets, UDP, TCP, etc.)

Nice to have

  • Good understanding of Unity engine

  • Experience working with ECS frameworks

  • Experience with code generation

  • Knowledge of cloud infrastructure concepts and technologies
