Frontend Engineer - Private Trading Platform

We’re hiring a Frontend Engineer to help build a brand-new execution platform within a private, proprietary trading environment. This role sits close to the trading desk, building real-time, performance-sensitive interfaces used directly by traders. You’ll be working on greenfield systems with high technical standards and immediate impact.

What you’ll be working on

• Designing and building trader-facing web applications
• Creating responsive, high-performance UIs for live execution workflows
• Collaborating closely with backend engineers and trading teams
• Contributing to architectural discussions and system design

What we’re looking for

• Strong JavaScript fundamentals
• Experience with modern frontend frameworks (React preferred)
• Solid understanding of software engineering principles
• Comfort working across the stack (not a purely UI role)
• Interest in finance or trading systems (deep domain knowledge not required)

Why this role stands out

• Greenfield platform — no legacy rewrite
• Direct exposure to live trading activity
• High-impact work in a proprietary environment (no clients)
• Strong engineering culture with a high technical bar

Location & setup

• Hybrid role: minimum 3 days per week onsite in Connecticut
• Remaining days flexible (NYC office or WFH)
• Relocation support available
