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 DoDesign 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 executionDevelop low-latency APIs and backend services supporting trading and order matchingIntegrate with blockchain networks, wallets, and smart contracts (EVM-based or others)Optimize concurrency, throughput, and fault tolerance across distributed systemsImplement monitoring, logging, and alerting for production-grade systemsContribute to system design, code reviews, and technical roadmapRequired Qualifications2+ years of professional experience with PythonStrong 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 modelsExperience building real-time systems (e.g., trading platforms, streaming pipelines, WebSockets)Proficiency with PostgreSQL, Redis, or similar data storesFamiliarity with Docker and cloud environments (AWS/GCP/Azure)Strong debugging, performance tuning, and code optimization skillsOptional: 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 appsNice to HaveExperience in crypto/web3 ecosystems (DeFi, prediction markets, exchanges)Experience with Rust, Go, C++ or other systems languagesWhat We OfferOpportunity to build a greenfield platform in a rapidly evolving spaceHigh ownership and autonomy in technical decision-makingFlexible remote work environmentCompetitive compensation + potential token upsideCollaborative, engineering-first cultureHow to ApplySubmit your CV, GitHub profile, and (if available) examples of async systems or real-time services you’ve built. Include a brief note on your experience with concurrency and distributed systems.
