Frontend Engineer

About the Position:

• You'll own the surface of JTX across web and mobile: order entry, market data, charts, positions, execution quality, onboarding, and wallet flows.
• You'll partner with design, product, and the infrastructure team, and make architectural calls that stick for years.
• The role suits a generalist with strong taste, comfortable with a live codebase and shipping fast.

What You'll Do:

• Build and own the JTX client across web and mobile, shipping real-time trading interfaces.
• Hit tight latency and render budgets against streaming market data, and decide what belongs on the client versus the server.
• Build wallet and signing flows, and own the shared component, state, and data layers.

What We're Looking For:

• 5+ years building production frontend, including something real-time, data dense, or financial.
• Deep React and TypeScript, with mobile experience in React Native or Expo.
• Security-first instincts around signing flows and key handling, and comfort with a live codebase.
