  • Ensure quality is maintained throughout our systems by contributing to code reviews and the design of last-line-of-defence systems
  • Provide advice and guidance to junior developers

Requirements

  • At least 5 years’ experience as a software engineer working with performance-critical high throughput or low latency systems
  • Skilled at object-oriented programming in C++, or Java/C# with a strong desire to work in C++
  • Strong understanding of network technologies (10G Ethernet, UDP, TCP) and Linux networking
  • Excellent understanding of computer science fundamentals like operating systems, data structures and algorithms
  • Excited by technically challenging problems
  • Embrace AI tools for parts of their role, without sacrificing code quality or runtime performance

Nice to have

  • Highly skilled in C++ development
  • Experienced working in a high frequency trading firm

What we offer
