Job Description
C++ Trading Platform Developer
A leading crypto-native algorithmic trading firm is looking for a C++ Trading Platform Developer to join its London-based team.
This is an opportunity to work at the intersection of high-performance engineering and digital asset markets, building and scaling a global trading platform that operates across dozens of exchanges worldwide. The environment combines the technical standards of top-tier high-frequency trading firms with the pace and ownership of a technology start-up.
You’ll work on a global, low-latency trading platform spanning multiple continents, covering:
- Real-time market data capture
- Order entry and connectivity across numerous exchanges
- Robust networking and monitoring systems
- Scaling and performance optimisation of core infrastructure
The tech stack is primarily C++ and Python, running on Linux across both development and production. The focus is on writing clean, scalable, high-performance code and continuously improving system reliability and speed.
This is a hands-on engineering role with direct exposure to traders and senior technical leadership. You’ll be given meaningful ownership from day one and the freedom to shape your impact.
What We’re Looking For
- Strong C++ skills (assessment will form part of the process)
- Deep understanding of data structures and performance optimisation
- Experience building client-server network applications
- Curiosity to understand how C++ standard libraries and systems work “under the hood”
- Strong analytical and problem-solving ability
Desirable:
- Knowledge of networking, CPU architecture, memory models, or assembly
- Interest in algorithmic or quantitative trading
Why Apply?
- Work on genuinely high-performance, real-time trading systems
- Significant ownership and responsibility early on
- Flat structure with direct access to senior leadership
- No legacy tech, no unnecessary bureaucracy
- Performance-based compensation with strong earning potential
- Central London office with flexible working arrangements (hybrid)
- Visa sponsorship and relocation support available
If you’re passionate about low-level systems, high-performance C++, and building robust trading infrastructure from the ground up, this is a rare opportunity to make a direct impact in a fast-moving market.
