Charting/WebGL Engineer

About TRADL AI:

TRADL AI is building India's first AI trading co-pilot for 100M+ traders.

Today, we convert natural language into verified, code-backed stock intelligence - no hallucinations, no black boxes. Tomorrow, we're building the full stack: real-time chart intelligence, autonomous research agents, and portfolio-aware execution. We're turning what institutional desks spend millions on into a conversation anyone can have. We're live, growing fast, and the hardest technical problems are still ahead of us.

We're live, growing fast, and the hardest technical problems are still ahead of us.

We are building the engineering team that will scale this from hundreds to hundreds of thousands of concurrent traders.

Why This Role Exists:

We're building our charting engine from zero. Native WebGL2. Sub-millisecond candle rendering at any timeframe. 100+ indicators computed on the fly. 50+ drawing tools. Multi-chart layouts. And an AI canvas layer that lets our models overlay pattern detection, support/resistance, anomaly flags, and annotations directly on the same surface as the price data. This role owns that engine.

What You'll Own

• AI-Charts Engine: Native charting system built ground-up in WebGL2 (or SciChart.js if the tradeoffs line up).

• Indicator Library: 100+ technical indicators computed in real time. Optimized math running in Web Workers so the main thread never blocks.

• Drawing Tools: 50+ drawing primitives - trend lines, Fibonacci, Elliott Wave, annotations, zones.

• AI Canvas Overlay: pattern detection, automated S/R, volume anomalies, earnings overlays. Build the rendering system that lets them paint on the chart in real time, without stalling the price feed.

• Performance: Sub-100ms rendering at production scale. GPU-accelerated. No dropped frames during market hours

What We're Looking For

• 4–8 years in frontend or graphics engineering, with production-scale WebGL/WebGL2 or Canvas2D experience.

• 3+ years at a startup - you've shipped under pressure and owned outcomes.

• High-performance JavaScript and TypeScript fluency.

• Web Workers - you know how to offload computation without the coordination overhead eating your gains.

• Working knowledge of financial chart types - candlestick, Heikin-Ashi, Renko and the data structures behind them (OHLCV, tick data, time-series aggregation).

Bonus Points

• Rust + WASM compilation for compute-heavy paths

• SciChart.js or direct experience with commercial charting SDKs

• SVG overlay systems composited over Canvas/WebGL

• GPU-accelerated rendering, shader programming

• Experience with TradingView, Highcharts Stock, or similar platforms at scale

• You've either built a custom charting system before or reverse-engineered one and believed you could do it better.
