Located in Chicago, Level Ex’s fast-growing game studio is transforming the way surgeons hone their skills by practicing high-risk surgeries with the latest medical devices in our industry-leading mobile, AR, and VR titles. Our games are built using state-of-the-art graphics and physics tech, and deploy an arsenal of well-designed game mechanics to capture the thrill and challenge of performing real surgery. These games increase dramatically in difficulty as the player progresses, and are carefully crafted with professional level design, compulsion loops, flow channels, and deliberate gameplay balance. Backed with a mature art pipeline and latest-gen engine tech, we’re able to recreate surgery with spectacular realism. Our engine has earned the trust of the country’s leading surgeons; plus, we’ve custom-built GPU-based real-time fluids, tissue shading, and soft-body systems that enable a wide range of new game mechanics in mobile and VR. Our team unites award-winning game designers, developers, and 3D artists with top surgeons, all passionate about using game design approaches to keep doctors across the world performing at the top of their game.


Ideal Candidate

  • BS or MS in Computer Science or equivalent

  • Experience authoring shaders in HLSL, GLSL and/or Cg.

  • Strong 3D math skills (linear algebra, matrix/vector math, trigonometry, etc.)

  • Background in computer graphics, including the fundamentals of lighting models, raytracing, rasterization, texture mapping, and shading

  • Basic understanding of GPU architecture

What You’ll Be Doing For Us

Level EX is looking for talented software engineers to work on next-generation, ultra-realistic 3D surgical simulators. Utilize cutting edge game engines, graphics, and physics techniques to create stunning simulations of the human body.

As a shader engineer, your role involves recreating elements of the human body in extreme detail in a real-time rendered environment: including tissue, blood, and fluids. Shader engineers utilize the latest computer graphics and shading techniques to achieve unprecedented realism.

Join a seasoned team of game and simulation developers to push the bleeding edge of simulated surgery and save some lives while doing it.

  • Create new shaders, shader nodes, and materials for a wide range of surfaces and visual effects under senior technical direction

  • Work closely with the art team to prototype new techniques and establish texture/modeling pipelines for production shaders

  • Implement performance optimizations and fallbacks for older devices


Bonus Points Awarded For

  • Experience with visual shader editors (ShaderMonkey, Unreal, ShaderForge)

  • Unity experience

  • Mobile shader development/optimization experience

  • 3D Graphics API experience (OpenGL or DirectX)

  • Metal experience
