Full Stack Developer for Trading Platform

Full-Stack TypeScript Engineer (Real-Time Trading System)

We are building a real-time copy-trading platform integrated with Polymarket.

This is not a marketing site or CRUD SaaS.
This is a latency-sensitive system involving:

* WebSockets (real-time leader trade detection)
* Background workers & job queues (BullMQ / Redis)
* Idempotent trade execution pipelines
* Concurrency control per user
* PostgreSQL (Drizzle ORM)
* Next.js 15 frontend
* Hono + tRPC API
* Redis streams
* Worker processes running outside serverless

We are looking for a strong systems-oriented TypeScript engineer who can operate across backend and frontend - with backend depth as the priority.

* Improving reconciliation and failsafe systems
* Enhancing dashboard + trading UX (Next.js)
* Refactoring for performance and clarity

---

Required Experience

You must have:
