Job description

Role Overview

You will architect and lead the development of the firm's entire market-making technology stack—from exchange connectivity and low-latency quoting engines to risk systems and monitoring infrastructure. This is a foundational role: you will shape system design, development practices, and technology standards from day zero.

Key Responsibilities

• Design and build a production-grade market-making platform (pricing engine, quoting engine, risk engine, order‑management, market‑data handlers, monitoring)
• Lead low‑latency engineering efforts within cloud‑based environments (AWS, GCP, etc.)
• Build robust exchange connectors and handle idiosyncrasies of different crypto derivatives venues
• Develop simulation/testing frameworks for strategy validation and stress testing
• Implement automated failover, redundancy, and protection against exchange outages, API degradation, and rate‑limit issues
• Collaborate closely with traders on strategy logic, pricing models, and operational workflows
• Establish engineering best practices, code quality standards, and deployment processes

Requirements

• 10+ years building market‑making, HFT, or real‑time trading system
• Strong expertise in C++/Rust for performance‑critical code; Python for research infrastructure
• Experience architecting trading systems end‑to‑end (market data, order routing, risk controls)
• Familiarity with cloud network performance and optimizing for low latency in a non‑co‑located environment
• Strong understanding of exchange APIs (WebSocket, REST, FIX variants)
• Prior experience collaborating directly with traders/quant teams
