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.

• Develop and optimize scalable rendering systems and features across a wide range of platforms
• Write robust, performant C++ and shader code that forms the backbone of our proprietary Glacier engine
• Profile, debug, and optimize rendering performance across CPU and GPU
• Collaborate with creative teams to build and extend render features with a strong focus on workflows
• Implement advanced rendering techniques for complex visual systems
• Support the technical direction and roadmap for rendering as we expand our render capabilities Who you are
• Strong C++ programmer with experience in engine-level graphics systems
• Proven expertise in shader programming (HLSL or equivalent)
• Experienced with work in large-scale codebases
• Strong grasp of GPU architecture, rendering pipelines, and graphics theory
• Comfortable working across multiple platforms
• Excellent communicator who can work effectively in a distributed, multicultural team environment




• High willingness to learn new things and drive topics and your own We especially want to hear from you if you are
• Experienced with graphics programming work in custom engines 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.
