Are you looking to work on problems that genuinely test the limits of performance, scale, and engineering craft? We are building a small, elite team of systems engineers to design and evolve the core infrastructure that powers a highly sophisticated trading platform. This is not application level development. This is deep work on performance critical systems where nanoseconds matter, correctness is non negotiable, and your decisions directly impact real world outcomes.
You will be working on the foundations of the trading stack, including market data, execution, simulation, and internal infrastructure. The problems are hard, the standards are high, and the impact is immediate. This is an environment built by engineers for engineers. You will have real ownership, real influence on architecture and direction, and the opportunity to rebuild and redesign systems end to end rather than maintaining legacy code.
What you will be working on:
- Designing and building high performance C++ systems that sit directly in the live trading path
- Optimising latency, throughput, and determinism across highly concurrent systems
- Working on market data capture, normalisation, and internal distribution at scale
- Building and evolving simulation and backtesting infrastructure used by researchers and traders
- Going deep on memory behaviour, data structures, and concurrency models
- Collaborating closely with traders and researchers on strategy and execution plumbing
What we are looking for:
- ~2 plus years of experience building performance critical systems in C++
- Strong background in performance optimisation across CPU, memory, and network boundaries
- Experience with low latency systems, distributed systems, or high throughput pipelines
- GPU or accelerator experience is a strong plus
- Comfortable working close to the metal and reasoning about systems behaviour
- A collaborative, low ego approach with the ability to own problems end to end
- Strong communication skills and the confidence to engage with senior technical stakeholders
Why this is different:
- Small, elite team with very high technical bar
- Real ownership and influence over core systems and architecture
- Direct line of sight between your work and live trading outcomes
- Exposure to complex, interesting problems that do not exist in most engineering roles
- Exceptional compensation and access to some of the strongest engineers in the industry
If you are excited by performance, systems engineering, and working on problems that actually matter, this is the kind of role where you can do the best work of your career.
