MARGO is a tech-native consultancy delivering elite software engineering expertise to the most demanding financial markets environments.

We operate in latency-critical trading contexts where performance, determinism and predictability are core system requirements. Our consultants work in highly specialised trading environments, designing systems that interact directly with exchanges and market venues under extreme time constraints.

You will join a High Frequency Trading / Low Latency Trading environment within one of our partners (investment banks, proprietary trading firms or market makers).

The teams design, build and operate latency-sensitive trading systems directly connected to exchanges, typically deployed in colocated environments.

These systems are characterised by:

We are looking for a C++ Software Engineer to work on latency-critical trading infrastructure.

The role is strongly engineering-driven and focuses on speed, predictability and control of execution rather than functional feature delivery.

Depending on the environment, the role may also involve interaction with C# components used outside the ultra-latency-critical execution path.

C# may be used outside the latency-critical execution path for:

C# is not used on the execution path and does not replace core C++ expertise.

This role is not suitable for candidates with a C#-only background.

Core execution systems are implemented in C++.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
