Skills
Full job details
We're looking for an experienced Graphics Programmer to step in and own our rendering systems as we continue development on multiple high-profile projects. This is an immediate need, and we need someone who can take full ownership of complex rendering challenges from day one.
We have a strong foundation in place, but we need a skilled engineer to stabilize and advance our graphics pipeline as projects scale. This role is about stepping into a critical position, taking ownership of proven systems, and ensuring rendering performance and quality across our portfolio. You won't be building from scratch; you'll be inheriting well-architected systems and the responsibility to maintain, optimize, and evolve them as our projects demand. If you thrive on ownership, solving real problems under deadline, and delivering results on systems that matter, this is the role for you.
What you will do
Own and maintain rendering systems and graphics pipelines across multiple projects and console generations
Write robust, performant C++ code that forms the backbone of our proprietary Glacier engine
Profile, debug, and optimize rendering performance across CPU and GPU, with deep focus on platform-specific constraints
Collaborate with engine systems teams to improve data flow, memory management, and rendering feature integration
Implement and optimize advanced rendering techniques for complex visual systems including cloth, crowds, terrain, weather, and environmental effects
Maintain and strengthen rendering architecture as projects move into production
Who you are
Shipped at least one AAA title as a Graphics/Rendering Programmer
Strong C++ programmer with deep experience in engine-level graphics systems
Proven expertise in graphics APIs (DirectX, Vulkan, or equivalent) and shader programming
Experienced with performance profiling and optimization in large-scale codebases
Strong grasp of GPU architecture, rendering pipelines, and graphics theory
Comfortable working across multiple platforms with a focus on console development
Excellent communicator who can work effectively in a distributed, multicultural team environment
Able to step into established systems and take ownership quickly
Why join us
You'll join a team where your work is immediately impactful and your ownership is valued. We're not asking you to build something from scratch; we're asking you to step into a critical role, maintain excellence, and help drive our projects forward. If you're looking for a position where you can make a real difference in a high-pressure environment, this is it.
