Solution Architect (Crypto/CEX)

Solution Architect – Ultra-Low Latency HFT Infrastructure (Crypto / CEX) ⚡🏗️

Location: any
💰14.000-16.000$ per month

💻We are looking for a visionary Solution Architect to lead the architectural evolution of our high-frequency trading platform, with a primary focus on Centralized Exchanges (CEX) — Binance, OKX, Bybit, Kraken, and others. You will define how our systems communicate with exchange gateways, process market data, and execute orders at scale.

The Mission:
Design and oversee the implementation of a next-gen trading ecosystem that connects to major CEX with sub-millisecond latency. You will own the end-to-end architecture, from market data ingestion to order execution and risk management, ensuring resilience against exchange-specific quirks and rate limits.

Core Architectural Areas:

CEX Integration Layer: Unified gateway architecture for multiple exchanges, handling WebSockets, REST, FIX, and private data feeds.

System Design: Microservices vs monolithic cores, message bus architecture, data flow optimization.

Performance: Implementation of kernel-bypass (Solarflare), NUMA-aware design, and lock-free data structures.

Cloud & Infrastructure: AWS-based deployment, auto-scaling, load balancing, and disaster recovery strategies.

Strategy Pipeline: Architecture for strategy backtesting, simulation, and live deployment.

Required Expertise:

📍 8+ years in systems architecture, with at least 5 years in HFT/FinTech focused on CEX.

📍 Deep expertise in C++ (20/23) and Linux systems programming.

📍 Proven track record of designing low-latency, high-throughput distributed systems for centralized exchanges.

📍 Strong knowledge of networking protocols (TCP/IP, UDP multicast, WebSockets) and exchange-specific APIs.

📍 Understanding of CEX microstructures: order books, matching engines, rate limiting, and WebSocket stability patterns.

📍 Experience with AWS (EC2, ECS, VPC, load balancers) is mandatory.

Why Join Us:

💰Competitive fixed compensation + significant discretionary P&L bonus — your architectural decisions directly drive revenue.

💻Full remote with flexible hours (aligned with European time).

🧠Work alongside top-tier quantitative and engineering talent in a flat, no-ego culture.
