I’m working with a leading quantitative research & technology firm who are hiring several C++ contractors across different teams. These roles sit within highly technical engineering groups building the foundations that power large-scale trading, analytics, and research systems.

Strong engineers who write clean, modern C++ and enjoy solving technical problems within trading and / or market data environments will be considered.

What They’re Looking For

• Solid understanding of systems fundamentals (memory, concurrency, performance, networking, etc.)

• Experience building reliable, production-grade software

• Ability to work independently and contribute to complex codebases

• Open to candidates from any industry — gaming, telecoms, HPC, defence, automotive, trading, etc.

Contract Details
