Job Description
We’re hiring a Frontend Engineer to help build a brand-new execution platform within a private, proprietary trading environment.

- Contributing to architectural discussions and system design
What we’re looking for

- 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)
