Description

Topstep is seeking a Staff Software Engineer to develop a custom charting engine for the TopstepX trading platform. The role involves creating a framework-agnostic library that renders real-time charts, focusing on rendering pipelines, frame budgets, and API design. The engineer will contribute to various aspects such as layer system, data plumbing, indicator math, drawing tools, and API development. They will also adapt the core for React and potentially React Native bindings, with plans for a WebGL layer.

Preferred Qualifications: Production experience with real-time streaming systems — WebSocket lifecycle, backpressure, reconnection, and replay.
React Native, react-native-skia, expo-gl, or JSI experience.
Order flow and market microstructure knowledge — footprint charts, volume profile, DOM, cumulative delta.
MessagePack or protobuf experience for binary serialization on the data pipeline.
WebGL2 experience
WebGPU / WGSL experience (long-term migration target).
Rust + WASM experience (the indicator compute layer is the most likely candidate for a Rust rewrite).

Open source contributions to graphics, charting, or financial libraries.
