Senior Frontend Engineer

Mentions an AI-assisted development mindset—uses AI tools for development practices and emphasizes responsible AI use.

Senior Frontend Engineer responsible for designing and building high-performance, real-time trading user interfaces using React, Next.js, and Type Script. The role focuses on handling streaming data, optimizing rendering for high-volume updates, and ensuring robust testing and CI/CD practices in execution/trading environments.

Senior Frontend Engineer focused on building high-performance, real-time applications for trading and execution technology environments. The engineer will design and implement responsive, low-latency UIs that handle high-frequency streaming data and integrate with trading workflows.

• Develop and maintain front-end applications using React, Next.js, and Type Script.
• Implement real-time data UIs using Web Sockets/streaming architectures, handling high-frequency updates, message ordering, and UI state consistency.
• Build and optimize tabular/data-grid interfaces for high-volume data rendering (e.g., AG Grid).
• Optimize web performance (rendering pipelines, virtualization, debouncing/throttling, memory management).
• Author and maintain automated tests using Playwright, Jest, and React Testing Library.
• Integrate with CI/CD pipelines and follow modern development workflows and Git-based source control.
• Apply an AI-assisted development mindset while exercising strong judgment around validation, testing, security, and responsible AI use.

• 6+ years of professional front-end engineering experience.
• Strong proficiency in React, Next.js, and Type Script.
• Experience building real‑time data UIs using Web Sockets / streaming architectures.
• Expertise with data grid/tabular UI libraries (e.g., AG Grid) for high-volume data rendering.
• Deep understanding of web performance optimization techniques (virtualization, debouncing/throttling, memory management).
• Experience with testing frameworks such as Playwright, Jest, and React Testing Library.
• Familiarity with CI/CD pipelines, Git, and modern development workflows.
• AI-assisted development mindset with strong judgment in validation, testing, security, and responsible usage.

• Prior experience in trading or execution technology environments.
• Understanding of trading concepts (order types, execution workflows, FIX protocol, P&L, market data).
• Exposure to EMS/OMS systems.

• Pay: $175,000 - $240,000 per year.
