About FalconX
FalconX is a digital asset brokerage and trading platform that connects institutional investors to the global crypto markets. We’re bridging the gap between traditional finance and digital assets through world-class infrastructure, high-performance trading systems, and an unwavering focus on reliability, scale, and innovation.

As a market leader serving hedge funds, asset managers, and financial institutions, we are building a next-generation platform for high- and low-touch trading workflows across spot, derivatives, and structured products.

About the Role
We’re looking for a Senior Trading Systems Developer with strong experience in Java and Rust to architect and build our next-generation Order Management System (OMS) and electronic trading execution platform. This platform will be central to supporting complex electronic trading workflows, such as market making and internalizing flow spanning high- and low-touch desks. You’ll be designing and developing scalable, low-latency components that are resilient under heavy load and tightly integrated with our execution stack and internal trading infrastructure.

Key Responsibilities

• Design and implement a high-performance OMS for institutional trading workflow and EMS for electronic trading strategies and internalization engines.
• Lead the development of core order lifecycle components: order entry, modification, routing, risk checks, and state management.
• Build scalable services using Java and Rust, optimized for latency and throughput.
• Collaborate with strategy developers, product managers, and infrastructure teams to deliver flexible and extensible trading systems.
• Ensure system resilience, observability, and recovery in distributed, high-availability environments.
• Integrate with external market venues and internal trading strategies using WebSocket, REST, and FIX APIs.
• Drive code quality, testability, and production readiness through CI/CD, monitoring, and alerting best practices.

Requirements

• 5+ years of experience designing and building distributed trading systems.
• Expertise in Java (11+) and Rust for performance-critical systems. C++ a plus.
• Experience building or significantly contributing to an Order Management System (OMS) or Execution Management System (EMS).
• Solid understanding of order state transitions, event-driven architecture, and low-latency system design.
• Experience with WebSocket, REST, FIX, and OpenSSL at the protocol level.
• Knowledge of market structure, trading workflows (high- and low-touch), market making, and electronic trading best practices.
• Experience with high-performance messaging frameworks (e.g., Aeron, Chronicle, ZeroMQ, Kafka).
• Strong computer science fundamentals in data structures, algorithms, concurrency, and memory management.
• Familiarity with cloud-native environments, performance tuning, and system observability.

Bonus Points

• Prior experience in crypto markets or electronic trading in traditional finance.
• Experience integrating OMS with strategy containers, risk engines, or smart order routers.
• Knowledge of FIX protocol nuances and connectivity to major exchanges.
• Exposure to container orchestration, service mesh, or hybrid deployment architectures.
