Overview

We are partnering with multiple tier-1 investment banks, buy-side trading firms, and digital asset market participants to hire senior C++ engineers for front office, revenue-critical platforms.

These teams build and operate low-latency, high-throughput trading systems spanning electronic execution, market access, prime brokerage, and digital asset infrastructure. The mandates include greenfield architecture, platform re-engineering, and scaling systems operating under strict performance and reliability constraints.

What You'll Be Working On

Depending on the mandate, you will:

  • Design and build high-performance C++ trading systems (pricing, execution, order management)
  • Architect and optimise low-latency exchange connectivity (FIX and native/binary protocols)
  • Contribute to algorithmic trading infrastructure and execution frameworks
  • Develop core components within prime brokerage or custody platforms
  • Lead performance optimisation initiatives across latency-sensitive and concurrency-heavy systems
  • Collaborate closely with traders, quants, and infrastructure teams in front office environments

Required Experience

  • C++ development (modern C++17/20 preferred)
  • Proven experience building high-throughput and/or low-latency production systems
  • Strong understanding of systems design, data structures, and performance trade-offs
  • Deep knowledge of Linux, multithreading, concurrency, and memory management
  • Experience operating in trading, financial services, crypto, or other real-time mission-critical environments

Nice to Have (Role Dependent)

  • Electronic trading / market access systems
  • FIX protocol or exchange connectivity
  • Algorithmic trading platforms or execution engines
  • Performance profiling, optimisation, and lock-free programming
  • Distributed systems or microservices architectures
  • Exposure to prime brokerage, custody, or digital assets
  • Python for tooling, research, or automation

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
