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.
