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

Solution Architect – Ultra-Low Latency HFT Infrastructure (Crypto/CEX). Location: any. Salary $14,000–$16,000/month. Lead architecture for HFT platform focused on centralized exchanges, market data, order execution, risk management.

Design and oversee a next-gen trading ecosystem connecting to major CEX with sub-millisecond latency. Own end-to-end architecture from market data ingestion to order execution and risk management. Core architectural areas: CEX integration layer (unified gateway for WebSockets, REST, FIX, private data feeds); system design (microservices vs monolithic cores, message bus architecture, data flow optimization); performance (kernel-bypass, NUMA-aware design, lock-free data structures); cloud & infrastructure (AWS deployment, auto-scaling, load balancing, disaster recovery); strategy pipeline (backtesting, simulation, live deployment).

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.

Competitive fixed compensation + significant discretionary P&L bonus — 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.
