Trading Systems Engineer
Join one of the top proprietary trading firms globally, known for its deep technical culture, elite trading teams, and cutting-edge market infrastructure. This particular role sits within a team behind a next-generation, multi-asset class Execution Management System used by leading hedge funds and asset managers.
As a Software Engineer on the trading technology team, you'll be working on high-throughput, low-latency systems that form the core infrastructure of the platform. This includes:
- Designing, developing and implementing a best-in-class execution management system
- Enhancing and modernizing a high-performance messaging router
- Migrating legacy features to a modern Java-based tech stack
- Supporting and evolving a real-time in-memory database environment for Linux
- Collaborating with reference and trading data services across the firm
- Contributing to core service development, while also partnering closely with UI/UX engineers to support and shape how backend services are surfaced to end users
Although this is primarily a backend-focused role, the team values engineers who have cross-stack awareness - familiarity with Java or C#/.NET-based UI layers is a big plus. You'll occasionally contribute to functionality that spans both the backend and client-side, especially in areas tied to performance, usability, and system integration.
What They're Looking For:
- 3-7 years of experience with Java, ideally in low-latency or distributed systems
- Proficiency with Linux-based development environments
- Exposure to Java or C#/.NET; full-stack experience is a bonus, but not required
- Comfort working across multiple systems and collaborating cross-functionally
- Experience with messaging systems, in-memory databases, or real-time applications is a plus
- Passion for clean code, scalable systems, and solving complex technical problems
