This is a senior engineering role for someone who has shipped real-time applications across web and desktop platforms and can build scalable, high-performance systems.

Key responsibilities

• Build and optimize real-time rendering systems including scene graphs, draw order, culling, batching, and level of detail
• Develop 3D and isometric rendering with camera systems, coordinate projection, depth sorting, picking, and hit testing
• Render large numbers of simultaneous entities without frame drops
• Design simulation and game loop architecture, including update/render separation, fixed timestep, and frame budgeting
• Build systems driven by live external state and reconcile updates under latency
• Implement real-time networking or state synchronization such as multiplayer netcode, replication, or client-side prediction
• Develop RTS, simulation, or management-game interaction patterns including unit selection, multi-select, control groups, camera control, order queueing, alerts, and notifications
• Profile and optimize performance across CPU, GPU, and memory, including lower-spec hardware
• Work within established art and design direction
