Lynx Capital Partners

We're building analytical instruments for traders, brokers, and retail investors — real-time tools that make sense of the US stock market as it moves. Startup pace, real infrastructure, direct customer impact.

We build with AI in the loop — our engineers use it to move faster and explore further, and we expect the same from you.

What You'll Do

• Build the real-time data layer: ingest market feeds, process tick data, serve low-latency responses to the UI that has to be right and fast at the same time
• Own the customer-facing side: charts, dashboards, analytical instruments that traders and brokers use to make decisions — in Rust where it needs to be fast, in JS/TS where the customer sees it
• Bridge the gap between the high-throughput backend and what renders on screen — you understand both sides and can make them work together without throwing the problem over the wall
• Use AI tools actively in your daily work — code generation, debugging, architecture exploration — and bring genuine curiosity about what they can and can't do

What We're Looking For

Must have:

• Rust — production experience, comfortable owning performance-critical services
• JavaScript or TypeScript — shipped customer-facing interfaces that real users interact with
• Experience with real-time or streaming data — you understand what it means when latency matters and data accuracy is non-negotiable
• You actively use AI tools in your daily workflow and can describe how they've changed the way you work — with genuine curiosity to go deeper
• 3+ years of professional software development, with meaningful time on systems where correctness and performance are both required

Nice to have (we'll work through the rest together):

• Financial domain: trading, market data, order book mechanics, price feeds
• WebSockets or SSE for real-time UI updates
• WebAssembly — especially Rust compiled to WASM for browser performance
• Familiarity with market data protocols or feeds (FIX, broker WebSocket APIs)
• Experience with high-throughput message systems (Kafka, Redpanda, or similar)
