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.

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.

What You’ll Do

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.

What We’re Looking For

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.
