About Us
We are a small but highly competitive proprietary trading firm of around 50 people, building cutting‑edge systems for high‑frequency and quantitative trading. Our size allows us to stay agile, move fast, and give engineers direct ownership over systems that matter.
We operate in a flat, engineering‑driven environment where decisions are quick, ideas are valued, and great engineers can have immediate and measurable impact on PnL.
The Role
We are looking for a C++ Software Engineer who wants to work on extremely challenging problems across ultra‑low‑latency trading systems, market data infrastructure, and exchange connectivity. You will collaborate closely with traders and other engineers to design, optimize, and deploy systems that operate at microsecond scale.
If you enjoy squeezing out nanoseconds, understanding hardware behaviour, and building systems that operate at the limit of what's technically possible, this role is for you.
What You'll Do
- Design, implement, and optimize high‑performance C++ components for real‑time trading.
- Build and refine low‑latency connectivity to global exchanges.
- Profile and optimize performance across network, CPU, and application layers.

You're a strong candidate if you have:
- Expert‑level skills in C++ (C++17/20 or above).
- Deep understanding of systems programming, memory, CPU internals, multithreading.
- Experience building or optimizing real-time, high-throughput, or latency-sensitive systems.
- Comfort in a fast-paced, iterative environment.
- Strong problem‑solving skills and a performance‑driven mindset.
Nice to Have
- Experience in HFT, market data, or exchange connectivity.
- Low‑latency networking expertise (UDP, kernel bypass, DPDK, etc.).
