Description & Requirements Description & Requirements

FXGO is a premier trading platform that allows traders to buy and sell currencies (FX) 24/5. The FX market is the largest market in the world, with more than $7 trillion traded every day. Our platform is used by the industry’s biggest players in over 120 countries to trade hundreds of billions of dollars with each other every day. Our trading applications are distributed, fault-tolerant, highly transactional, and low-latency.

Our Team

The FXGO Lifecycle Core team is the foundational post-execution data engine of the entire platform. We own the foundational data layer of FXGO which is responsible for the accuracy, consistency, and reliability of trade data across its entire lifecycle.

While upstream teams build the specific trading workflows, our systems catch every single trade the millisecond it executes. We design, build, and scale the critical infrastructure responsible for real-time trade capture, robust distributed storage, and high-volume event distribution in a highly concurrent environment.

By owning the core post-trade data models and messaging pipelines, we are the trusted, event-driven source of truth that reliably feeds downstream business applications like straight-through processing (STP), billing, and regulatory reporting. Our goal is to ensure our backend infrastructure can seamlessly absorb and distribute data during extreme market volatility without bottlenecking the platform.

The core engineering challenge here is moving massive volumes of events reliably between distributed systems while maintaining strict data correctness. No trade can be missed.

Who are you?

You are an engineer who thinks in terms of systems, infrastructure health, and scalability. This is an opportunity to engineer resilient systems and ensure absolute data correctness at the heart of one of Bloomberg's premier FX trading platforms.

You are someone who takes pride in true service ownership - you want to move beyond tactical feature delivery to build robust, long-term solutions. You are excited by the challenge of working across distributed data storage, real-time messaging pipelines, and the reliability of high-volume financial infrastructure.

You’ll Need To Have

• 5+ Years of experience building production-ready, high-performance applications in C++
• A Degree in Computer Science, Engineering, Mathematics, a similar field of study, or equivalent work experience
• An aptitude for problem-solving and a desire to build software solutions for complex business workflows, with experience across the full software development lifecycle
• A passion for driving technology, architecture, and product evolution

We’d Love To See

• Deep experience designing and scaling high-volume, high-availability distributed systems
• Good working knowledge of relational databases and messaging queues (preferably PostgreSQL and Apache Kafka)
• Experience with API design, contract-driven testing, and decoupled architectures
• A mindset focused on observability, capacity planning, and system resilience

If indicated, please note that years of experience are a guide; we will consider applications from all candidates who can demonstrate the skills necessary for the role.
