United Kingdom Fortis Games Full time

At Fortis Games we aspire to make great games that bring people together while redefining how game companies work. We believe in building a sense of belonging through our games, their communities, and how we operate and treat each other. Through our game communities, we will create powerful connections and lasting memories. We will foster a culture of diversity, equity and belonging where together our diverse skills, experiences and backgrounds impact the games we make.

Fortis is building games where players truly belong - and our first title, Twilight Towers , just hit soft launch. We’re looking for a Staff Game Engineer to help take it global.

Architect scalable, data-oriented systems for ECS, animation, physics, and UI frameworks
Lead investigations into CPU, GPU, and memory bottlenecks, defining baselines and measurable performance targets
Refactor complex gameplay code for clarity, modularity, and performance
Mentor engineers in Unity performance patterns, Burst/Job System usage, and mobile optimization practices
Collaborate with design, art, and backend teams to deliver new features that meet both creative and performance goals
Contribute to the long-term Unity architecture and client scalability strategy across titles
Deep hands-on experience building and optimizing Unity (C#) game clients at scale
Expertise in mobile performance optimization, including CPU/GPU profiling, memory management, and asset streaming

We're not just about making Games Where You Belong. We're also about building communities where our people belong. That's why Fortis is a thriving environment that celebrates diversity, embraces inclusivity, and fosters growth.
