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.

---

What You’ll Work On

* Improving and maintaining real-time copy-trade execution pipelines
* Handling queue grouping, retries, and concurrency limits
* Writing clean, idempotent trade handlers (buy/sell/redeem)
* Improving reconciliation and failsafe systems
* Enhancing dashboard + trading UX (Next.js)
* Refactoring for performance and clarity

---

Required Experience

You must have:

* Strong TypeScript (strict mode, production experience)
* Next.js + React (App Router preferred)
* Node/Bun backend experience
* WebSockets in production
* Redis + background job systems (BullMQ or similar)
* PostgreSQL experience
* Experience designing systems that handle race conditions

Bonus:

* Trading platforms
* Financial systems
* Blockchain / web3
* CLOB-based order execution systems

---

What We Care About

* Clean architecture thinking
* Concurrency awareness
* Defensive programming
* Proper error handling
* Clear communication
* No ego-driven engineering

We care far more about systems thinking than UI polish.

---

Screening Process

1. Work ethics, non technical interview with COO.

2. Technical interview (architecture-focused) with CEO.
2. Small paid test task (4–6 hours)
3. 4 week paid trial period

We do not hire based on interviews alone.

---

Engagement

* Long-term opportunity
* Flexible timezone overlap required
* Direct collaboration with founder + lead engineer
* No agencies

About the Role

We’re looking for a Fullstack Engineer with strong experience building AI-powered products to help us grow our gaming & infrastructure platform.

You’ll join a fast-moving, AI-first team where you’ll design, build, and ship features end-to-end — from model integration and prompt engineering to the UI users interact with. You’ll work with LLMs, video generation, and ML pipelines as part of your daily workflow, using AI tools to move faster and build better.

This role is ideal for someone who already builds with AI in production, thinks in terms of product value, and wants real ownership — not just coding tickets. At PlayMe, we move fast, avoid bureaucracy, and give engineers full ownership to make decisions and deliver impactful products used by real people.

How to apply:

Write us a short note on this:
How do you think software engineering — and the place of humans in it — is changing in the AI era? What excites you, what worries you, what feels overrated? And where do you see yourself in all of it?
Write it yourself. Spell-check, grammar tools — go for it. But don't outsource the thinking to an LLM. We want to hear how you actually think. If we hire you based on an essay you didn't write, neither of us wins - we are still hiring human intelligence and we are looking for the mindset match with our business values.

Who You Are

• You have 5+ years of software engineering experience with a track record of shipping production-ready products;
• You are fullstack — comfortable working with both backend and frontend;
• You have hands-on experience with AI in production (LLMs, ML models, or generative pipelines);
• You’ve built or integrated solutions using LLMs, LangChain, MCP, or similar tools;
• You actively use AI tools (e.g., Claude Code, Codex) to improve your development workflow;
• You understand AWS ecosystem and basic DevOps practices;
• You think in terms of product impact, not just implementation;
• You’ve worked in small, fast-moving teams, shipping frequently and iterating quickly;
• You’re independent, ambitious, and ownership-driven;

• You have Upper-Intermediate+ English.

   

Nice to Have

• Experience with video generation, diffusion models, or multimodal pipelines;

• Background in machine learning (fine-tuning, inference optimization, evaluation).

   

What You’ll Do
