Senior Python Developer (Async Systems) — Crypto & Prediction Markets Platform

About the RoleWe are building a next-generation crypto-native prediction markets trading platform focused on low-latency trading, real-time data ingestion, and high-throughput event processing. We’re looking for a Senior Python Developer with deep expertise in asynchronous programming to architect and implement core backend systems that power trading, pricing, testing, and market resolution.

This is a high-impact role where you will shape system design decisions from the ground up in a fast-moving, technically rigorous environment.

What You’ll Do

• Design and implement high-performance async services using Python (e.g., asyncio, FastAPI, aiohttp)
• Build and maintain event-driven architectures for real-time market data and trade execution
• Develop low-latency APIs and backend services supporting trading and order matching
• Integrate with blockchain networks, wallets, and smart contracts (EVM-based or others)
• Optimize concurrency, throughput, and fault tolerance across distributed systems
• Implement monitoring, logging, and alerting for production-grade systems
• Contribute to system design, code reviews, and technical roadmap

Required Qualifications

• 2+ years of professional experience with Python
• Strong experience with asynchronous programming paradigms (async/await, event loops, concurrency patterns)
• Hands-on experience with async frameworks (e.g., FastAPI, Starlette, aiohttp)
• Solid understanding of distributed systems, message queues (Kafka, RabbitMQ, NATS), and pub/sub models
• Experience building real-time systems (e.g., trading platforms, streaming pipelines, WebSockets)
• Proficiency with PostgreSQL, Redis, or similar data stores
• Familiarity with Docker and cloud environments (AWS/GCP/Azure)
• Strong debugging, performance tuning, and code optimization skills

Optional: GUI / Desktop Development (Qt6)

• Experience building desktop or operator-facing tools using Qt6 bindings for Python (e.g., PySide6, PyQt6)
• Ability to design responsive, event-driven GUIs that integrate with async backends (e.g., bridging Qt event loop with asyncio)
• Familiarity with model view patterns in Qt (MVC/MVVM) and efficient rendering of real-time data (charts, order books, logs)
• Building internal tools such as trading dashboards, monitoring consoles, or market visualization apps

Nice to Have

• Experience in crypto/web3 ecosystems (DeFi, prediction markets, exchanges)
• Experience with Rust, Go, C++ or other systems languages

What We Offer

• Opportunity to build a greenfield platform in a rapidly evolving space
• High ownership and autonomy in technical decision-making
• Flexible remote work environment
• Competitive compensation + potential token upside
• Collaborative, engineering-first culture
